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.

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition associated with the peculiarities of the nervous system's functioning, attention regulation, impulses, and motor activity.

A condition in which the adrenal glands' ability to adequately respond to stress and maintain stable hormone production—primarily cortisol, adrenaline, and aldosterone—is diminished. With prolonged stress, the stress response system gradually becomes depleted, leading to metabolic disturbances, reduced resilience to stressors, and a decline in overall well-being.

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.

Are states of heightened reactivity of the immune system, in which the body begins to perceive safe substances as threats. An allergic reaction is not an independent disease in the classical sense, but reflects deep disturbances in immune regulation, barrier functions, and nutrient exchange.

A progressive neurodegenerative disorder that leads to a gradual decline in memory, intellect, and the ability to perform everyday activities. It is the most common form of dementia and most often develops in people over 65, although it can occur earlier.

Anemia means low hemoglobin or red cells; causes include iron, B12 or folate deficiency, blood loss, inflammation and kidney disease.

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.

A condition in which there is a temporary cessation of breathing during sleep. Such episodes can occur multiple times throughout the night, causing a decrease in blood oxygen levels and negatively affecting the functioning of the heart, blood vessels, and brain.

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.

Acute respiratory viral infection is a group of viral airway infections; nutrition supports recovery but does not replace care for breathlessness, high fever or worsening.

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.

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.

Bulimia combines binge episodes with compensatory behavior; key risks involve electrolytes, heart, esophagus, teeth and mental health.

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.

Not a single disease, but a whole group of conditions in which cells lose the ability to control their division and begin to grow uncontrollably. These pathological cells disrupt the functioning of organs, form tumors, and can spread throughout the body, forming metastases.

Thrush, or candidiasis, — is a fungal infection caused by the excessive growth of yeast-like fungi of the genus Candida, most commonly Candida albicans. The disease can affect the mucous membranes of the genital organs, oral cavity, intestines, and skin.

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 clouding of the lens that gradually worsens vision; nutrition supports eye health but does not dissolve an established cataract.

An autoimmune condition in which the consumption of gluten triggers an inflammatory response in the small intestine. This leads to damage to the mucous membrane and disrupts the absorption processes of nutrients.

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.

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

One form of acne associated with the dysfunction of sebaceous glands and skin renewal processes. Their formation is based on a combination of increased sebum production, slowed shedding of dead skin cells, and changes in the microbial balance of the skin.

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.

An infectious disease caused by the SARS-CoV-2 virus, first identified in China at the end of 2019. Within a few months, the virus spread worldwide, causing a pandemic that changed the medical, social, and economic life of humanity.

Crohn's disease is a chronic inflammatory bowel condition that usually calls for long-term support rather than one-time fixes.

Dementia is persistent cognitive decline; causes differ, so diagnosis, safety, sleep, vascular factors and nutrition matter.

Depression affects mood, sleep, energy, thinking and the body; nutrition can support care but does not replace therapy or medical help.

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.

Eating disorders affect not only food intake but also control, body image, guilt and fear; with keto, restrictive behavior may worsen.

Dry eye syndrome comes from tear film disturbance and causes burning, gritty sensation, redness, eye fatigue and fluctuating vision.

The excessive accumulation of fluid in the tissues, which leads to swelling, a feeling of heaviness, and an increase in the volume of certain areas of the body. It is not an independent disease but a signal that the water-electrolyte balance is disrupted, particularly related to sodium regulation.

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.

Elevated LDL should be interpreted together with triglycerides, ApoB, diet, and the broader metabolic picture rather than as an isolated number.

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.

A chronic gynecological condition in which tissue similar in structure to the endometrium (the uterine lining) grows outside the uterine cavity. Lesions can localize on the ovaries, peritoneum, intestines, bladder, and other structures of the pelvis.

A chronic neurological condition characterized by increased seizure readiness in the brain. The disease is associated with an imbalance between excitatory and inhibitory processes in the nervous system, leading to periodic epileptic seizures.

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 linked to excess fat accumulation in liver cells and usually requires careful work with diet, metabolism, and daily habits.

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.

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 in the gallbladder; symptoms depend on stone movement, inflammation and response to fatty food.

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; causes include Helicobacter pylori, NSAIDs, alcohol, bile reflux, severe stress and autoimmune processes.

A group of diseases that lead to damage to the optic nerve and can cause vision loss. This condition is often associated with increased intraocular pressure, although it is not always the cause.

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.

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.

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.

A condition in which the body accumulates excessive amounts of iron and loses the ability to effectively regulate its absorption and distribution. Iron is a key element for the functioning of enzymes, mitochondria, and detoxification systems; however, its excess becomes a pro-oxidant factor and damages tissues.

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.

The human immunodeficiency virus (HIV) is a retrovirus that attacks the immune system's cells, primarily CD4 lymphocytes. The gradual decrease in their numbers leads to a weakening of the immune response and a loss of the ability to effectively defend against infections and tumor processes.

Sudden heat and sweating episodes are often linked to menopause, but new or severe symptoms require other causes to be ruled out.

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.

Hyperthyroidism is excess thyroid hormone; it accelerates metabolism, strains the heart and may look like anxiety or unexplained weight loss.

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

A condition in which the production of hydrochloric acid is reduced to the extent that normal digestion, food sterilization, and nutrient absorption are disrupted. A lack of acid leads to the growth of pathogenic flora, reduced protein digestion, deficiencies in minerals and vitamins, as well as systemic health consequences.

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.

A condition in which the oxygen content in arterial blood falls below the physiological norm. A lack of oxygen hinders the work of cells, disrupts metabolism, and reduces the function of the brain, heart, and respiratory system.

Hypoxia means insufficient oxygen in tissues; causes may be respiratory, cardiac, vascular, anemic, altitude-related or toxic.

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.

Is the absence of pregnancy in a couple with regular sexual life without contraception for 12 months. For women over 35 years old, the waiting period is usually reduced to 6 months.

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.

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.

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 causes chronic abdominal pain and stool changes without structural damage, but diagnosis requires excluding warning signs.

(IHD) is a chronic condition that arises from insufficient blood supply to the heart muscle (myocardium). When blood flow decreases, the heart receives less oxygen and nutrients, leading to pain, rhythm disturbances, and reduced contractile ability.

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.

A condition in which the kidneys stop effectively filtering blood, removing toxins, maintaining normal water-electrolyte balance, and regulating blood pressure. Disruption of kidney function leads to the accumulation of metabolic products, changes in potassium, sodium, and fluid levels in the body, and also affects the heart, hormonal system, and overall health.

Lactose intolerance results from low lactase activity and causes bloating, pain, gas or diarrhea after milk and some dairy foods.

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.

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 means elevated lymphocyte count; it may be a reaction to infection, inflammation or stress, but sometimes blood disease must be excluded.

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.

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.

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 chronic joint disease involving cartilage, bone and surrounding tissues; symptoms are influenced by weight, muscles, load and inflammatory factors.

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.

Oxalate stones are a common kidney stone type; risk depends on urine volume, dietary calcium, oxalates, citrate, salt and metabolic factors.

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.

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

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.

(PCOS) is an endocrine-metabolic disorder in which the ovaries produce an excessive amount of androgens (male hormones), leading to disruptions in ovulation, menstrual cycles, and metabolism. The condition is accompanied by insulin resistance and increased insulin production, which exacerbates hormonal imbalance and hinders follicle maturation.

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.

A condition in which an increased amount of protein is found in the urine. A small amount of protein may be present in a healthy person, but a pronounced or persistent increase is an important laboratory sign.

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.

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.

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.

Small Intestinal Bacterial Overgrowth (SIBO) is a condition in which the number of bacteria in the small intestine exceeds the normal level. Normally, bacteria are mainly concentrated in the large intestine, while there are few in the small intestine.

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.

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.

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 condition that often requires careful work with diet, the intestinal lining, and the risk of depletion.

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

A pathological process in which calcium salts are deposited in the walls of arteries and other blood vessels. As a result, the vessels lose elasticity, become stiffer, and are less able to adapt to changes in blood flow.

Vegetative-vascular dystonia (VVD) is a functional disorder of the regulation of the autonomic nervous system, in which the mechanisms for maintaining stable vascular tone, heart function, breathing, digestion, and stress responses are impaired.

Visceral obesity is excess fat around internal organs; it is strongly linked with insulin resistance, inflammation and cardiovascular risk.
