Diseases and conditions

Inflammatory changes in the skin of the face, associated with the functioning of sebaceous glands and the condition of hair follicles, occur in people of all ages and can vary in severity. In clinical practice, this spectrum of conditions is grouped under the term acne.

ADHD is a neurodevelopmental condition that affects attention, self-regulation, impulsivity and behavioral organization, so it is important to understand not only distractibility but also sleep, overload, emotions, study, work and everyday function.

Adrenal fatigue syndrome is a popular but controversial label usually used to describe exhaustion, stress overload and poor adaptation, so the practical task is not to stop at a simple explanation, but to assess sleep, thyroid status, deficiencies, inflammation and emotional strain more carefully.

An inflammatory reaction of the nasal lining to allergens that usually shows up as congestion, sneezing, itching, and watery discharge. It is important to distinguish it from the common cold and plan support with triggers, seasonality, and coexisting asthma in mind.

Allergies are immune reactions to usually harmless substances, and the key is to understand not only rash, itching or sneezing, but also the reaction type, the trigger, the risk of systemic spread and the difference between allergy and intolerance.

A progressive neurodegenerative illness affecting memory, reasoning and daily independence that requires early review of sleep, vascular risk, deficiencies, medications and caregiving conditions rather than a simple dementia label.

Androgenetic alopecia is not simply general hair shedding but a gradual miniaturization of follicles driven by androgen sensitivity and genetics; early recognition, correction of compounding deficiencies, and realistic long-term strategy matter more than random cosmetic measures.

Low hemoglobin or red-cell count reduces oxygen delivery to tissues and should be traced to its cause: iron, B12 or folate deficiency, blood loss, inflammation, kidney disease or another chronic disorder.

Anemia of chronic disease does not arise mainly because iron stores are empty, but because long-term inflammation alters iron handling and makes red-blood-cell production less effective; it often accompanies chronic infections, autoimmune disease, inflammatory bowel disease, kidney disease, or malignancy, so the hemoglobin value has to be read together with the inflammatory and iron-transport context.

Inflammation and cracking at the mouth corners often involve saliva irritation, Candida, bacteria, dentures, iron deficiency, B2, B12, folate, or overall poor nutritional status.

A dangerous eating disorder with food restriction, fear of weight gain and distorted body image can quickly affect the heart, hormones, bones, blood and mental state and requires coordinated medical and psychological care.

Anosmia is loss of smell that may result from viral infection, inflamed nasal mucosa, polyps, trauma, neurological causes or impaired odor conduction, so the mechanism must be identified rather than treating it as a trivial symptom.

Autoimmune coagulation disorder in which antibodies to phospholipid-associated proteins increase the risk of venous and arterial thrombosis, pregnancy loss, and placental complications. It is important to confirm antibodies again, assess vascular risks, and have medical supervision when selecting anticoagulant therapy.

Persistent anxiety, internal tension and nervous system overload can interfere with sleep, concentration and daily life. For anxiety disorders, it is important to look at sleep, stress, physical causes, and seek professional help for severe symptoms.

Sleep apnea is more than snoring: repeated breathing pauses disrupt sleep, blood pressure, metabolism, and daytime function, so they deserve real evaluation rather than casual dismissal.

Acute inflammation of the appendix that often begins with pain near the navel and then moves to the right lower abdomen; the condition is dangerous because of the risk of perforation and requires prompt medical evaluation.

Joint pain can be a consequence of overload, inflammation, metabolic disorders or systemic diseases, so arthralgia is considered a symptom and not a self-sufficient explanation of the cause. Context, accompanying signs and timely assessment are important for the correct tactics.

Not a single disease, but a group of conditions in which the inflammatory process affects the joints and the surrounding tissues. For the patient, this manifests as pain, morning stiffness, reduced mobility, and, in some cases, swelling.

An acute respiratory viral infection is not one specific virus but a group of infections in which temperature, breathing, hydration, sleep, nutrition and complication risk matter more than the simple presence of cough or runny nose.

A chronic inflammatory disease of the airways, in which the bronchial mucosa becomes hypersensitive to irritants. This causes periodic attacks of wheezing, shortness of breath, a feeling of tightness in the chest, and coughing.

A chronic process inside arterial walls in which inflammation, lipoproteins, blood pressure, glucose, smoking and immune reactions form plaques. The key issue is not only cholesterol, but ApoB, endothelial function, metabolic context and plaque stability.

A neurodevelopmental condition associated with the peculiarities of brain formation and functioning, where the processing of sensory information, social interaction, and communication is altered.

A group of chronic pathologies in which the immune system fails to distinguish between "self" and "non-self" and begins to produce antibodies against its own cells and tissues. As a result, inflammatory processes develop, gradually damaging organs and systems, disrupting their function.

With autoimmune thyroiditis, it is important to look beyond TSH alone and consider antibodies, symptoms, thyroid structure, and the broader metabolic background, including micronutrient status.

Back pain is a common problem that affects people of all ages. It can be caused by various factors, including poor posture, physical strain, and injuries. Proper diagnosis and treatment play a key role in alleviating symptoms and restoring functionality. Regular exercise and taking care of back health can help prevent recurrences.

Bad breath is most often linked not to the stomach but to the mouth, tongue coating, dryness, gum disease, tonsils, or the upper airway; the source, timing, and accompanying symptoms matter more than the smell alone.

Enlargement of prostate tissue often shows up as a weaker urine stream, nighttime urination, and incomplete emptying. It is not the same as prostate cancer, but it still deserves attention because it affects quality of life and urinary function.

A severe thiamine deficiency disease that can damage nerves, the heart, and energy metabolism; risk rises with alcohol use, undernutrition, vomiting, malabsorption, and high carbohydrate intake without enough B1.

A bent or kinked gallbladder is an anatomic variant or deformation that is not always harmful by itself, but may influence gallbladder emptying, tolerance of fatty meals and bile stagnation risk when it matches real symptoms.

A chronic mood-regulation disorder with episodes of depression, mania or hypomania requires not only psychiatric care, but also attention to sleep, stress, substances, thyroid function and metabolic stability.

Lyme borreliosis is a tick-borne infection that can affect skin, nerves, joints and the heart, so timing of the bite, symptom pattern, erythema migrans and disease stage matter more than a test result alone.

Brittle nails often reflect a wider nutritional, protein, thyroid, or stress-related background rather than a purely local cosmetic issue.

A chronic inflammatory airway disease with episodes of wheeze, cough, and breathlessness; diet may improve background risks but does not replace inhaled treatment or an action plan.

A repetitive involuntary clenching or grinding of teeth, which most often occurs during sleep but can also manifest while awake. This condition occurs in people of various ages, including children and adults.

Repeated binge episodes followed by vomiting, laxatives, fasting or exhausting exercise are dangerous for electrolytes, the heart, esophagus, teeth and mental health even when body weight looks normal.

Burns affect not only the skin and pain level, but also tissue barrier function, fluid losses, infection risk, and the need for protein and micronutrients during recovery.

Cancer is not one disease but a large group of malignant processes in which cells lose normal growth control, so what matters is not only the existence of a tumor but also its type, stage, organ of origin, biology and the overall state of the person.

Thrush is more than temporary irritation: recurrent episodes deserve a deeper look at antibiotics, diabetes, mucosal care, and the factors that keep Candida overgrowth returning.

Candida overgrowth becomes clinically significant when the balance of mucous membranes, skin, immune control or carbohydrate metabolism is disturbed, so candidiasis requires precision rather than universal explanations for all symptoms. Recurrent episodes are useful to evaluate in conjunction with background glycemia, medications, and barrier disorders.

A group of heart muscle diseases can impair pumping function, rhythm stability and exercise tolerance. Nutrition, electrolytes and metabolic health may support care, but cardiomyopathy requires medical diagnosis, follow-up and treatment.

Cardiovascular diseases are a group of conditions that affect the heart and blood vessels. They include hypertension, coronary artery disease, and stroke. The main risk factors are poor nutrition, a sedentary lifestyle, and stress. Prevention and early diagnosis play a key role in reducing morbidity and mortality.

Cataract is a clouding of the eye lens that gradually reduces clarity, contrast and night vision; nutrition may support eye health, but it does not dissolve an established opacity, so real visual function and timing of surgery matter most.

Celiac disease is an autoimmune disorder in which gluten triggers damage to the small-intestinal lining, so the relevant picture includes not only bloating or diarrhea, but also anemia, nutrient deficits, skin, bones, cycle, fertility and silent forms of disease.

Chronic cough is a long-lasting symptom that may indicate various conditions, including allergies, asthma, and respiratory infections. Its duration exceeds eight weeks, and it requires careful examination to identify the cause and prescribe appropriate treatment. Ignoring such a symptom is not recommended.

In chronic fatigue syndrome, rest stops restoring energy fully, so stress alone is not enough to assess; deficits, sleep, and load tolerance also matter.

Chronic stress affects sleep, appetite, pain sensitivity, energy production, and mineral balance, so it needs to be viewed not only psychologically but also metabolically.

An advanced stage of chronic liver scarring in which normal architecture, blood flow, and functional reserve are disrupted; it should be interpreted together with the cause, signs of portal hypertension, synthetic liver function, and the broader metabolic context.

Combined oral contraceptives and hormone replacement therapy may change micronutrient needs, which is why folates are often considered part of broader preventive nutritional support.

Comedones are early acne lesions formed by blockage of the pore with sebum and keratin, so the real issue is not only blackheads themselves but sebaceous-gland activity, skin turnover, skincare pattern, hormonal context and inflammation.

A common viral infection of the upper respiratory tract most often goes away on its own, but still significantly affects sleep, well-being and performance. If you have a cold, rest, fluids, and paying attention to signs of a more severe cold are helpful.

Constipation is not only infrequent stool but also straining, hard stool, pain, and a feeling of incomplete emptying. The cause is not just diet: hydration, salt, medicines, thyroid function, intestinal motility, and pelvic floor coordination matter, and fiber does not help everyone and can worsen bloating in some people.

Excess free copper can burden the liver, intensify oxidative stress, and produce a mix of digestive, neurologic, and mood-related symptoms. Proper evaluation depends not only on lab tests, but also on why copper is accumulating in the first place.

Covid-19 is a viral infection that can affect not only the airways but also vessels, clotting, the heart, the nervous system and the general metabolic background, so the key issue is not only fever and cough but also severity and recovery after the acute phase.

Crohn’s disease is a chronic inflammatory bowel disease that can impair absorption, protein status, body weight, and food tolerance well beyond ordinary digestive discomfort.

Loss of fluids and electrolytes affects far more than thirst alone; it changes blood pressure, pulse, kidney function, temperature control and muscle performance, so dehydration requires cause-based evaluation and severity assessment.

Decline in memory, orientation and everyday independence in dementia requires searching for causes, assessing vascular and metabolic factors, sleep, medications, hearing, vision and care conditions rather than relying on a label alone.

Depression is not simply a bad mood, but a state that can reduce energy, interest, sleep quality, appetite and daily functioning, so it requires clinical evaluation rather than shame or delay in getting help.

Diabetes insipidus is a disorder in which the body loses too much water because antidiuretic hormone is lacking or the kidneys do not respond to it properly; it is typically considered when intense thirst and very large volumes of dilute urine appear together.

Chronic glucose dysregulation has different forms: type 1, type 2, gestational, pancreatogenic, and other diabetes types require different decisions. Low-carb nutrition may reduce glycemic load, but medication adjustment, hypoglycemia risk, and ketoacidosis risk need medical attention.

Peripheral nerve damage in diabetes can result in burning, numbness, pain and decreased sensation, especially in the feet. For diabetic neuropathy, glucose control, foot care, and prompt medical evaluation are important, not just symptom management.

Diarrhea is not limited to infections: it can be triggered by gastrointestinal viruses, food-related irritation, medications, SIBO, bile-acid problems, and inflammation, while the main immediate risks are dehydration, electrolyte loss, and missing a dangerous cause.

An eating disorder is not weak discipline but a disordered relationship with food, body and control in which obsessive thoughts, bingeing, restriction, shame, anxiety and physical consequences can reshape daily life and health.

Dry eye syndrome is a disorder of tear-film stability in which burning, grittiness and fluctuating vision depend not only on “too few tears,” but also on tear quality, meibomian glands, screen load and ocular-surface inflammation.

Edema is not simply extra water in the tissues but a symptom that may reflect salt handling, venous return, lymph flow, kidneys, heart, protein status, hormones and medication, so the key question is not only where swelling appears but why fluid is being retained.

Elevated cholesterol levels in the blood can lead to serious diseases, such as atherosclerosis and cardiovascular problems. It is important to monitor your diet by avoiding saturated fats and trans fats, as well as increasing the intake of fiber and healthy fats to maintain cardiovascular health.

A high HbA1c indicates that blood glucose levels have been elevated not just on a single day, but on average over the past weeks and months, which is why this measure is used to assess chronic glycemic load. However, it should be interpreted alongside fasting glucose, insulin, clinical picture, and conditions that alter the lifespan of red blood cells; otherwise, the number may be misleading.

Chronically elevated insulin often appears before fasting glucose becomes obviously abnormal and points to strained carbohydrate regulation. It is most often linked to insulin resistance, visceral obesity, high glycemic load, and poor sleep, so it is best interpreted together with glucose, HOMA-IR, lipids, and waist circumference.

Elevated LDL should not be read in isolation: its meaning depends on triglycerides, ApoB, insulin resistance, thyroid function, and the broader metabolic setting.

Increased blood urea is not automatically equal to kidney disease: it can rise due to dehydration, excess protein, catabolism, gastrointestinal bleeding, the use of certain medications, and decreased renal filtration. This result is important to interpret alongside creatinine, GFR, clinical situation, and overall protein context, rather than as a standalone diagnosis.

Hyperuricemia means that uric acid accumulates in the blood faster than the body can eliminate it; this increases the risk of gout, uric acid stones, and often reflects an unfavorable metabolic background. It is important to evaluate such analysis along with kidney function, hydration, nutrition, alcohol, medications, and signs of insulin resistance, rather than attributing the cause solely to meat or purines.

The late stage of chronic kidney disease in which kidney function is no longer sufficient to safely remove fluid, potassium, phosphorus, acids, and metabolic waste. Nutrition must be individualized with a nephrologist, dialysis team, and current laboratory results.

Endometriosis is a chronic disorder in which tissue similar to endometrium grows outside the uterus and drives pain, inflammation, adhesions, cycle-related symptoms and fertility problems, so evaluation must go beyond “bad periods” alone.

Epilepsy is a condition of increased tendency toward recurrent seizures caused by abnormal synchronous electrical brain activity, so it is important to understand not only the seizure itself but also its type, cause, triggers and safety implications.

Recurring erectile issues often reflect not only a local sexual difficulty but also the condition of the blood vessels, glycemia, sleep, hormonal balance, and psycho-emotional health.

A condition in which the influence of estrogen is relatively stronger than that of progesterone. It is discussed in cases of mastopathy, PMS, heavy menstruation, fluid retention, mood swings and cyclical breast tenderness, but it must be assessed not by one symptom, but by a combination of complaints, tests and metabolic context.

Fatty liver is an early marker of metabolic overload linked to insulin resistance, triglycerides, body weight, and diet quality rather than a harmless incidental ultrasound finding.

Fatty liver disease refers to the accumulation of excess fat in liver cells and is often associated with insulin resistance, visceral obesity, and elevated triglycerides.

Fibromyalgia often brings diffuse pain, poor recovery, and sleep problems, so support usually needs to be broader than a single symptomatic measure.

A process of excessive connective tissue formation after chronic injury, inflammation, or organ stress. It matters in the liver, lungs, heart, kidneys, pancreas, and other tissues because scarring changes organ structure and gradually reduces function.

Folate deficiency is a state of low folate in which DNA synthesis, blood formation and the renewal of rapidly dividing tissues are impaired, so it is important to assess not only diet but also gut function, alcohol, pregnancy, medications and the link to B12 deficiency.

Folate deficiency is a state of inadequate folate supply in which cell division, blood formation, mucosal health and fetal development suffer, so it is important to assess not only diet but also alcohol, gut function, medications, pregnancy and the broader deficiency background.

A fracture is a break in bone integrity that requires not only fixation and time, but also full support for tissue repair, protein intake, minerals, and controlled inflammation. Nutrition and targeted support may improve recovery, but they never replace trauma care and the correct treatment strategy.

Gallstone disease means stones form in the gallbladder or bile ducts; what matters is not only the ultrasound finding, but pain, bile flow, inflammation and the risk of complications.

After gastrectomy, digestion and nutrient absorption change for the long term, so food tolerance and deficiency risks usually need closer follow-up.

Gastritis is inflammation of the stomach lining that may relate to Helicobacter pylori, medications, alcohol, stress, impaired mucosal protection and meal patterns, so understanding the cause matters more than simply suppressing discomfort.

Peptic ulcer disease is a deeper defect of the stomach or duodenal lining linked to Helicobacter pylori, NSAIDs, acid exposure and weakened mucosal defense, so the cause, bleeding risk and complication profile matter more than symptom suppression alone.

GERD is a condition in which stomach contents reflux into the esophagus often enough to cause heartburn, regurgitation, cough or mucosal injury, so triggers, weight, meals, sleep and complications all matter, not symptom relief alone.

Gestational diabetes is a disturbance of carbohydrate metabolism during pregnancy that requires timely laboratory control and careful follow-up.

Gilbert syndrome is an inherited bilirubin-metabolism variant in which unconjugated bilirubin rises intermittently without major liver damage, so what matters is not only the number itself but also the conditions that amplify its fluctuations.

Glaucoma is dangerous not only because of eye pressure, but because of gradual optic-nerve damage that may progress with few symptoms, making regular eye care more important than waiting for pain.

A metabolic disease in which the level of uric acid in the body increases and its crystals deposit in the joints, causing pain, swelling, and inflammation. The joint of the big toe is most often affected, but over time, the knees, elbows, and other joints may also be involved.

Granulomatosis is an inflammatory disease characterized by the formation of granulomas — small nodules made up of immune cells. This condition can affect various organs, including the lungs, skin, and lymph nodes, and often requires a comprehensive approach to diagnosis and treatment to manage symptoms and prevent complications.

Graves disease is an autoimmune cause of hyperthyroidism in which the immune system overstimulates the thyroid gland; it often presents with suppressed TSH, elevated thyroid hormones, palpitations, anxiety, heat intolerance, and a broader systemic metabolic acceleration.

The gradual loss of hair pigment, most often linked with age, genetics, oxidative stress, and accompanying deficiencies. It is useful to distinguish ordinary age-related graying from unusually early graying that appears together with other warning signs.

Hair loss is often linked not only to cosmetic care or genetics, but also to nutrient deficiencies, thyroid status, stress, rapid weight loss, and overall food quality.

Hashimoto thyroiditis is an autoimmune thyroid disorder in which the immune system gradually damages thyroid tissue; in practice it is one of the most common causes of hypothyroidism and persistently elevated thyroid antibodies.

A condition in which the heart cannot supply tissues with blood efficiently requires medical monitoring, fluid control, blood pressure management, medication safety, and treatment of underlying causes. Low-carb nutrition may help metabolic risks, but salt, diuretics, potassium, and rapid weight changes need supervision.

Helicobacter pylori is not just a label for gastritis but a chronic stomach-mucosa infection that can raise the risk of ulcers and impair local protection; confirmation, mucosal assessment, and proper context matter more than symptoms alone.

Hemochromatosis is a state of iron overload in which the body stores more iron than it needs, so it is important to assess not only ferritin but also transferrin saturation, the liver, glucose metabolism, joints and family background.

One of the most common diseases affecting the anal area causes discomfort and unpleasant sensations. Hemorrhoids can manifest as inflammation of the veins, leading to pain, itching, and bleeding. Proper diagnosis and treatment can help address the problem and improve quality of life.

Inflammation of the liver that can develop because of viruses, alcohol, medications, autoimmune processes, and other damaging factors. Interpretation depends on the cause, lab pattern, liver function, and the risk of chronic progression.

After the first infection, the virus remains in the nerve ganglia and may recur during stress, sleep deprivation, fever, overheating, or immune strain, so frequent flare-ups call not only for creams but also for a review of triggers, sleep, nutrition, and the real need for antiviral treatment.

A chronic viral infection targeting CD4 immune cells that requires early diagnosis, regular viral-load monitoring, treatment adherence and attention to nutrition, coinfections and overall health rather than fear alone.

Hot flashes are often menopausal, but their intensity is shaped by sleep, stress, triggers, and metabolic background, so they are not always just a harmless sign of age.

Infection with human papillomavirus often occurs without symptoms, but some types require close monitoring if they persist for a long time. In case of HPV infection, the key remains screening, medical supervision and only then discussion of supportive nutritional measures.

Blood glucose above the normal range: it is important to distinguish a single post-meal rise from persistent dysregulation, diabetes, medication effects, and stress responses.

Elevated homocysteine ​​in the blood is often associated with deficiencies of folate, vitamins B12 and B6, as well as other metabolic and somatic factors. With hyperhomocysteinemia, it is important not only to reduce the figure, but also to understand the cause of the folate cycle disorder.

Persistently elevated arterial pressure: it should be confirmed by proper measurements, causes should be considered, and stroke, heart, kidney, and vascular risk should be reduced.

Excess thyroid hormone accelerates metabolism, increases cardiac strain, amplifies anxiety and weight loss, and should be assessed through TSH, free T4, free T3, the cause of thyrotoxicosis and its complications.

High triglycerides usually reflect energy excess, insulin resistance, liver overload, and broader metabolic imbalance rather than an isolated lab abnormality.

Low stomach acid is a state of reduced gastric acidity in which not only protein digestion and post-meal heaviness suffer, but also microbial defense, mineral absorption and the whole upper-GI digestive process.

Blood glucose low enough to deprive the brain and nervous system of readily available fuel; especially dangerous in people using insulin or glucose-lowering medication.

Low blood pressure is judged by symptoms and context: it may be normal for one person or signal dehydration, medication effects, bleeding, infection, or endocrine causes.

A condition in which the thyroid gland does not produce enough thyroid hormones (T3 and T4), which regulate metabolism, thermoregulation, and energy balance. With their deficiency, all processes in the body slow down — from brain function to digestion and circulation.

Hypoxemia is reduced oxygen level in arterial blood, and it matters not only as an oxygen-saturation number but as a sign that ventilation, lung gas exchange, pulmonary blood flow or oxygen delivery are no longer working normally.

Lack of oxygen in tissues is not a standalone diagnosis and should trigger a search for a problem in the lungs, heart, circulation, blood, altitude exposure, poisoning or impaired cellular oxygen use.

Persistent internal tension, difficulty relaxing, and sensitivity to stress may reflect a state of increased anxiety. Here it is important to take into account sleep, stimulants, somatic causes and, if necessary, seek professional help in time.

The tendency to make hasty decisions, breakdowns and weak inhibition of impulses may reflect not only character, but also overload of the nervous system, problems with sleep, attention and stress regulation. Increased impulsivity requires not self-criticism, but a more accurate understanding of the causes and supportive strategies.

During acute infections, the burden on immunity, antioxidant defense, hydration, and electrolyte balance rises, so supportive nutritional strategies have to be evaluated with extra care.

Absence of pregnancy despite regular unprotected intercourse requires assessment of both partners, including ovulation, sperm quality, thyroid status, weight, inflammation, nutrient deficiencies and wider metabolic context.

The acute onset, high fever, aches and extreme weakness make the flu a more severe infection than the common cold. In this condition, rest, monitoring for signs of complications, and timely medical evaluation in at-risk groups are especially important.

A state in which tissues respond poorly to insulin forces the pancreas to produce more hormone to control glucose. It is linked with visceral fat, fatty liver, blood pressure, triglycerides, sleep, stress and muscle mass.

A state in which muscle, liver, and fat tissue respond poorly to insulin, forcing the pancreas to secrete more of it. It can hide behind normal fasting glucose for years, so waist size, triglycerides, HDL, fasting insulin, HOMA-IR, and post-meal responses matter.

Insulinoma is a tumor that can produce insulin autonomously and trigger recurrent hypoglycemia; suspicion becomes stronger when glucose is low but insulin and C-peptide are not appropriately suppressed and symptoms improve after eating.

Low iodine intake affects thyroid hormone production first, so it is best assessed through diet, geography, labs, and the broader thyroid context rather than by symptoms alone.

Iron deficiency anemia develops when iron depletion has progressed far enough to impair hemoglobin production rather than only lowering reserves; it is commonly linked to blood loss, malabsorption, pregnancy, or longstanding iron deficiency, and the real task is to identify why the body ran out of usable iron in the first place.

An irregular menstrual cycle means that periods come too early, too late, or with long unstable gaps between them. This pattern is linked not only to stress, but also to ovarian function, thyroid status, prolactin, low energy availability, inflammation, and the broader hormonal context.

Irritable bowel syndrome is a functional bowel disorder with pain, bloating and stool changes in which chronic gut sensitivity and motility disturbance must be distinguished from inflammatory, infectious and structural causes.

Coronary heart disease is a condition in which the heart muscle receives too little blood and oxygen because of coronary-artery disease, so what matters is not only chest pain but also exercise tolerance, breathlessness, risk factors and the wider vascular background.

Jade is a valuable semi-precious stone known for its healing properties and cultural significance in various civilizations. It is used in jewelry and art objects, as well as in traditional medicine to improve health and harmonize the energy flows in the body. Jade symbolizes purity and wisdom.

A dangerous state in which ketone bodies accumulate together with a serious acid-base disturbance. It should not be confused with ordinary nutritional ketosis: ketoacidosis requires urgent medical assessment, especially in type 1 diabetes.

The presence of ketone bodies in urine can be normal during fasting, low-carbohydrate eating and exercise, but in diabetes with high glucose it becomes an important warning sign. Urine strips mainly reflect acetoacetate and are affected by hydration, so the result must be read with symptoms and context.

Kidney failure is a state of reduced renal filtration and regulatory function in which not only creatinine and urea are affected, but also fluid balance, blood pressure, acid-base control, blood formation and the wider metabolic background.

Lactose intolerance is impaired digestion of milk sugar due to low lactase activity, and the real issue is not only bloating or diarrhea, but also dose, type of dairy product, intestinal context and the distinction between intolerance and allergy.

Milk stasis during breastfeeding is more often caused by incomplete emptying of the breast, pressure on the ducts, or long intervals between feedings. It is important to quickly relieve the engorgement and distinguish ordinary stasis from the onset of mastitis, when an in-person medical assessment is already needed.

Liver failure is a serious state in which the liver can no longer adequately detoxify metabolic products, synthesize essential proteins, and maintain biochemical balance; it is considered when jaundice, weakness, swelling, bleeding tendency, and signs of major liver dysfunction appear.

Decreased dopamine activity may affect motivation, attention, cravings for rapid stimuli, and the ability to withstand effort, but should not become a harsh label without assessing sleep, stress, deficits, and mental background. It is more helpful to look at dopamine as part of a broader regulatory system rather than as the sole explanation for all complaints.

A condition in which basal or postprandial insulin secretion is insufficient for normal adaptation to nutrition and glucose levels. It is less common than insulin resistance, but can also cause weakness, tremors, poor hunger tolerance, weight loss, unstable energy and problems with recovery, so it requires investigation by tests rather than guesswork.

Low libido is often linked not only to age, but also to stress load, androgen status, sleep quality, vascular tone, medication effects, and overall metabolic health.

Low testosterone is associated with lower libido, reduced energy, weaker muscle function, and poorer mood resilience. It often coexists with obesity, sleep loss, and metabolic dysfunction.

Lymphocytosis is an increase in lymphocytes on a blood count that may accompany viral infection, recovery after illness, chronic immune stimulation and, more rarely, hematologic disease, so it must be interpreted in context rather than by panic over one number.

Magnesium deficiency can affect muscles, sleep, the nervous system, and stress tolerance, so both repletion and cause assessment matter.

With malabsorption, the body may receive nutrients with food but absorb them incompletely. This is especially important for vitamin B12 deficiency and other nutrient gaps, when the diet itself is not the only issue; the intestine and stomach must also be able to absorb what is eaten.

Mastopathy usually refers to benign changes in the breast tissue, which often result in swelling, cyclical tenderness, and a feeling of graininess or lumps. The term itself does not negate the need for examination: similar complaints must be distinguished from cysts, mastitis, and more serious causes of changes in the breast.

Maxillary sinusitis is inflammation of the maxillary sinus, where mucus is only part of the story: swelling of the drainage opening, facial pressure, discharge pattern, fever, dental factors, and the risk of prolonged or complicated infection all matter.

Megaloblastic anemia is an anemia in which DNA synthesis and blood-cell maturation are impaired, so it is important to investigate not only low hemoglobin but also B12 or folate deficiency, gut causes, medications and the broader background of disturbed hematopoiesis.

Reduced ability to encode new information, sustain attention, and retrieve memories quickly is not always a matter of aging. Poor sleep, chronic stress, depression, B12 or folate deficiency, iron deficiency, insulin resistance, alcohol, and some medications can all significantly worsen memory performance.

Menopause is the phase when menstruation stops and the hormonal background changes, influencing sleep, mood, vascular reactivity, bone turnover, body composition, and stress tolerance. Some women move through it smoothly, while others need more deliberate work with sleep, metabolism, nutrition, and medical strategy.

A combination of abdominal obesity, carbohydrate and lipid metabolism disorders, and high blood pressure, which significantly increases the risk of type 2 diabetes, cardiovascular complications and fatty liver disease.

Migraine is not just head pain. It also reflects nervous system excitability, trigger sensitivity, sleep quality, hydration, and the body’s ability to tolerate daily stressors.

Muscle cramps are often linked not only to overworked muscles, but also to fluid-electrolyte imbalance, poor recovery, and possible magnesium deficiency.

Muscle pain may reflect not only local overuse, but also poor recovery, electrolyte loss, and disturbed neuromuscular balance.

A broad name for kidney damage affecting filtration, blood vessels, glomeruli, tubules or interstitial tissue. Causes may include diabetes, hypertension, medications, autoimmune disease, infections, inherited disorders and chronic inflammation.

Nephrotic syndrome is a state in which the kidneys lose large amounts of protein into the urine; this leads to edema, altered protein balance, and shifts in laboratory markers that depend on circulating transport proteins.

Neurasthenia traditionally refers to a state of nervous exhaustion marked by fatigue, irritability, poor concentration, and low tolerance to ordinary stress. Today these symptoms are more often interpreted through chronic stress, burnout, anxiety, depressive states, sleep disruption, and metabolic causes rather than as one isolated label.

A group of conditions in which the function and survival of nerve cells are gradually impaired; it includes diseases with increasing deterioration of memory, motor functions, coordination and other neurological processes.

A chronic metabolic condition in which excess fat tissue disrupts hormonal, inflammatory and energy regulation. Weight alone is not enough: visceral fat, waist size, insulin resistance, blood pressure, sleep and comorbidities matter.

Osteoarthritis is a chronic joint disorder involving cartilage, bone and surrounding tissues in which body weight, muscles, loading, pain and function matter at least as much as the X-ray image itself.

A systemic disease of the skeleton, characterized by decreased density and disrupted microstructure of bone tissue. This makes bones more fragile and increases the risk of fractures, especially of the spine, hip, and wrist.

Otitis is inflammation of the ear and may involve the outer ear canal, the middle ear, or more rarely deeper structures. Practical importance lies not only in pain and fever, but also in hearing loss, discharge, nasal congestion, and the risk of complications, especially in children.

Oxalate stones form through a combination of oxalate load, urine chemistry, hydration and calcium handling, so evaluation should include fluids, diet, gut health and laboratory context rather than a simplistic blacklist of foods.

Pancreatitis is inflammation of the pancreas that may be acute or chronic and should be interpreted through upper abdominal pain, enzyme changes, food tolerance, biliary factors, and the broader digestive context.

Repeated panic attacks and the fear of their recurrence can severely limit daily life. For panic disorder, medical evaluation, working with triggers, and systemic support are important, not just trying to wait out the attack.

Parkinson's disease is not defined only by tremor; it also affects movement speed, rigidity, sleep, mood, autonomic regulation, and daily resilience, so early recognition and careful adjustment of nutrition and treatment context matter.

Pellagra is a state of niacin deficiency or impaired niacin availability that may affect skin, the GI tract and the nervous system, so it should be understood not only through rash but also through malnutrition, malabsorption, exhaustion and systemic consequences.

Periods of stress often come with poorer sleep, shifts in appetite, inner tension, and a greater need for restorative lifestyle and nutritional support.

Severe inflammation of the peritoneum that develops when infection, bile, intestinal contents, or blood enter the abdominal cavity; the condition requires urgent medical care.

An infectious-inflammatory lesion of lung tissue, during which the alveoli fill with fluid and immune system cells. This blocks normal gas exchange and leads to a decrease in blood oxygen levels.

Polycystic ovary syndrome is not only irregular periods and cysts on ultrasound, but a hormonal and metabolic condition in which ovulation, androgens, insulin resistance, body weight, skin and long-term reproductive risk all matter.

A state of increased red blood cell mass or concentrated red blood cell fraction; true polycythemia must be separated from dehydration and read together with hematocrit, hemoglobin, red blood cells, oxygen status, and thrombotic risk.

Recovery after surgery depends not only on the procedure itself, but also on protein intake, micronutrient status, inflammation control, and the pace of collagen formation.

Folate support is especially important before conception, during pregnancy, and during breastfeeding because these periods increase demand for cell division, methylation, and the broader folate cycle.

The period before menstruation finally stops is accompanied by hormonal instability, which can affect sleep, mood and metabolism. Perimenopause requires not panic, but careful attention to the cycle, symptoms and overall support strategy.

The recurring complex of physical and emotional symptoms in the second phase of the cycle can significantly affect sleep, appetite, work performance, and tolerance to stress. In the case of PMS, it is important to monitor the cyclicity of complaints, adjust underlying factors, and conduct a medical evaluation in the presence of severe or atypical symptoms.

Inflammation or chronic irritation in the prostate area may cause urinary discomfort, pelvic pain, sexual symptoms, and a general drop in well-being. It is important to distinguish acute infection from chronic pelvic symptoms and not rely on diet or supplements alone without proper medical assessment.

Protein deficiency affects more than muscle mass: it can weaken repair, resilience, and metabolic stability, so it is best interpreted together with diet, total protein, albumin, and digestive context.

Proteinuria is the presence of protein in the urine, which may be transient or may point to glomerular injury, renal stress, inflammation or systemic disease, so the crucial issue is not only the protein itself but why it appeared there.

Psoriatic skin disease is a chronic immune-inflammatory condition in which the pathological process affects not only the skin but also the entire body as a whole.

Pyelonephritis is an infectious inflammatory process in the kidney and renal pelvis where fever, flank pain, hydration status, bacterial spread, and the reason urine flow was disrupted all matter, not only urinary discomfort.

Pyridoxine-dependent epilepsy is a rare vitamin B6-related metabolic disorder that requires a distinct clinical approach rather than generic seizure management.

Radiation matters not only in disasters and radiotherapy: the biological impact depends on the type of exposure, the dose, the duration, tissue sensitivity, marrow reserve, mucosal integrity, skin response, and the ability to recover after injury.

Recovery after a viral illness may remain slow because of lingering inflammation, sleep disruption, autonomic imbalance, and nervous-system depletion; gradual activity, adequate nutrition, correction of deficiencies, and reassessment of red flags are important.

A chronic autoimmune inflammatory joint disease that can progressively damage tissue and requires early diagnosis rather than being dismissed as ordinary strain or aging.

Riboflavin deficiency is a lack of vitamin B2 in which energy metabolism, mucosa, skin, eyes and enzyme systems suffer, so it is important to assess not only diet but also gut function, alcohol, broader deficiency patterns and the state of rapidly renewing tissues.

Rosacea is a chronic inflammatory and vascular skin condition that causes persistent facial redness, flushing, visible vessels, skin sensitivity, and sometimes acne-like inflammatory bumps. Flares are often intensified by sun exposure, heat, stress, alcohol, spicy foods, and disruption of the skin barrier.

Rotavirus infection often causes watery diarrhea, vomiting, weakness, and rapid dehydration, especially in children; the key priorities in the first hours are oral rehydration, fluid control, and watching for red flags.

Runny nose most often reflects inflammation of the nasal mucosa from viral infection, allergy, irritation or vasomotor triggers, so it is important to distinguish a short-lived cold from a prolonged process affecting sleep, breathing and recovery.

Sarcopenia is loss of muscle mass and strength that affects not only appearance but also walking, stability, metabolism, recovery and fall risk, so the key issue is not only weight but actual muscle function.

Schizophrenia is a serious psychiatric disorder affecting perception, thought, emotion and social function, so it requires clinical assessment, monitoring of sleep, stress, substance exposure, nutrition and treatment tolerance rather than stigma.

Seborrhea is a disorder of sebaceous-gland activity and skin-barrier balance in which oiliness, flaking, inflammation, skin microbiome, hormones, stress and daily care all matter more than one random cream or shampoo.

A chronic inflammatory skin condition with peeling, itching and redness most often occurs on the scalp and seborrheic areas of the face. For seborrheic dermatitis, regular care, assessing triggers, and seeing a doctor if symptoms are severe or recurring are important.

Low selenium status can affect antioxidant defense, thyroid hormone metabolism, and recovery from inflammatory stress, so it is best assessed through diet, symptoms, and labs together.

Reactivation of the chickenpox virus usually causes a one-sided band of pain and blistering rash along a nerve; early risk assessment and pain control matter because postherpetic neuralgia may persist after the skin heals.

SIBO is small-intestinal bacterial overgrowth, a syndrome in which bloating and gas reflect not only fermentation itself, but also motility, bile flow, stomach acid, prior infections, diet and the conditions that allow overgrowth to persist.

Sideroblastic anemia is a form of anemia in which iron is present but not incorporated into heme correctly, so what matters is not only hemoglobin but also iron handling, bone-marrow biology, B-vitamin status, toxins and the causes of impaired blood formation.

Darkening of patches of skin is usually due to inflammation, sun, hormonal factors, or trauma to the skin, so hyperpigmentation requires understanding the cause rather than just trying to lighten the spots. The basics remain UV protection, gentle care and, if necessary, dermatological evaluation.

Problems falling asleep, night awakenings and shallow sleep affect not only morning alertness, but also appetite, mood and metabolism. When it comes to sleep problems, it's important to look for the cause and not settle for random short-term solutions.

Nicotine addiction affects not only the lungs but also the blood vessels, inflammatory background, metabolism, and stress tolerance; quitting smoking requires not shame, but a clear plan and support.

Stroke is an acute disruption of blood flow to the brain or a brain hemorrhage; after the emergency phase, blood pressure, glucose, vascular risk control, nutrition, rehabilitation, and recovery of cognitive and motor function become especially important.

Subacute thyroiditis is an inflammatory thyroid disorder that often follows a viral trigger and can temporarily produce a thyrotoxic pattern, neck pain, and unstable thyroid laboratory results across different phases.

Systemic lupus erythematosus is an autoimmune disease with fluctuating activity that may involve skin, joints, kidneys, blood, serosal surfaces and the nervous system, so assessment must combine symptoms with laboratory evidence of activity.

A condition in which the resting heart rate typically exceeds 100 beats per minute in adults. It is not a standalone disease but a symptom that can arise from various conditions: a physiological response to physical exertion and stress, dehydration, fever, side effects of medications, as well as various diseases.

Thalassemia is an inherited group of hemoglobin-synthesis disorders in which red blood cell formation is altered; it can resemble iron deficiency anemia in parts of the laboratory picture while having a completely different origin.

Thallium is a highly toxic metal that can cause a combination of gastrointestinal symptoms, limb pain, hair loss, and nervous system injury. It requires urgent medical evaluation because the clinical picture often evolves in stages and may affect the heart, liver, kidneys, and peripheral nerves.

The condition in which blood clots form in the blood vessels can lead to serious health consequences. Thrombosis often affects the venous system, causing swelling and pain, and can also lead to more dangerous complications, such as pulmonary artery thromboembolism. Prevention and timely treatment play a key role.

Thyrotoxicosis is a state in which tissues are exposed to an excess of thyroid hormones; it may present with palpitations, tremor, sweating, weight loss, anxiety, and requires not only hormone measurement but also clarification of the cause behind the excess.

An autoimmune disease with absolute or severe insulin deficiency requires lifelong insulin therapy and careful glucose management, not diet changes alone. A low-carbohydrate diet may reduce glucose swings, but it requires dose adjustment, ketone awareness and protection from hypoglycemia.

A metabolic disease usually driven by insulin resistance, excessive liver glucose output and declining beta-cell compensation. Low-carbohydrate eating, reduced visceral fat, movement and sleep can greatly improve control, but medication changes should be made with medical supervision.

Ulcerative colitis is a chronic inflammatory bowel disease that affects not only bowel symptoms but also protein status, iron balance, hydration, and food tolerance.

Dilated superficial veins usually reflect valve failure and increased venous pressure; nutrition can support the background, but compression, movement, and vascular assessment remain central.

Vascular calcification is calcium deposition in the vessel wall that makes arteries stiffer and is linked not only to aging, but also to inflammation, calcium-phosphate imbalance, kidney disease, diabetes and broader vascular risk.

Vegetative-vascular dystonia is not a precise stand-alone diagnosis but an old umbrella term that often hides autonomic dysregulation, anxiety, blood-pressure and pulse instability, breathing complaints and many symptoms that need a more specific explanation.

Visceral obesity is fat accumulation around internal organs that is closely linked to insulin resistance, inflammation, fatty liver and cardiovascular risk, so waist size, glucose, lipids and lifestyle matter more than weight alone.

Vitamin B12 deficiency can manifest not only as anemia, but also numbness, memory loss, weakness and other neurological symptoms. With B12 deficiency, it is important not only to replenish, but also to find the cause, especially if there are malabsorption or gastric surgery.

Vitamin B6 deficiency is a state of low pyridoxine in which amino-acid metabolism, the nervous system, blood formation and skin health are affected, so it is important to assess not only diet but also alcohol, gut function, medications, protein status and neighboring B-vitamin deficiencies.

Vitiligo is a pigment disorder marked by pale skin patches, where the visible spots are only part of the story; autoimmune background, sun sensitivity, skin trauma, nutrient status, and the pattern of progression all matter.

Warts are benign skin growths linked to human papillomavirus that depend on virus type, skin condition, friction and immune response, so location, trauma and persistence matter more than the idea that they are only a cosmetic issue.

Severe brain injury from thiamine deficiency: Wernicke encephalopathy needs urgent B1 treatment, while Korsakoff syndrome can leave persistent memory impairment.
