Hormone replacement therapy

Hormone replacement therapy (HRT) is a medical approach aimed at replenishing hormone deficiencies that arise due to age-related changes, endocrine system diseases, or surgical removal of hormone-producing organs.

The decrease in sex hormone levels significantly affects metabolism, fat distribution, bone and muscle condition, as well as the body’s energy balance. Therefore, proper nutritional support and dietary adjustments play an important role in HRT.

In the practice of nutrition, hormonal status is considered one of the key factors determining metabolic characteristics. Changes in estrogen, progesterone, or testosterone levels can influence tissue sensitivity to insulin, protein synthesis rates, inflammation levels, and appetite regulation. For this reason, diet and lifestyle can significantly enhance or, conversely, weaken the effects of hormone therapy.

Definition

Hormone replacement therapy is a medical strategy for correcting hormonal deficiencies, using estrogen, progestin, testosterone, or their combinations. The main goal of therapy is to restore the physiological hormonal background and reduce symptoms associated with its decline.

HRT is most commonly used:

• during menopause and postmenopause in women;
• in men with hypogonadism;
• after surgical removal of ovaries or testes;
• in some endocrine disorders;
• for the prevention and treatment of osteoporosis related to hormone deficiency.

In addition to alleviating unpleasant symptoms such as hot flashes, sleep disturbances, decreased libido, or chronic fatigue, hormone therapy can improve bone tissue condition, maintain muscle mass, and affect blood lipid profiles. However, any changes in hormonal levels inevitably affect metabolism, making nutrition an important part of a comprehensive approach.

Influence of Hormones on Metabolism

Sex hormones play a significant role in regulating metabolic processes. Their decrease can be accompanied by changes in fat distribution, loss of muscle mass, and impaired carbohydrate metabolism.

The main metabolic effects of hormones include:

• estrogens maintain tissue sensitivity to insulin and participate in regulating fat metabolism;
• testosterone stimulates muscle protein synthesis and helps maintain strength and endurance;
• progesterone affects water-salt balance and the nervous system;
• hormone deficiency can enhance the accumulation of visceral fat;
• decreased estrogen levels are associated with accelerated bone mass loss.

Therefore, individuals with hormonal changes often experience fluctuations in body weight, changes in appetite, and decreased energy levels. In this context, nutrition becomes a tool for stabilizing metabolic processes.

Forms and Methods of HRT

Modern medicine uses various forms of hormonal medications, allowing for the selection of the optimal option considering the patient’s health status and individual characteristics:

• oral medications – tablets with estrogens or their combination with progestins;
• transdermal forms – patches and gels that deliver hormones through the skin;
• injectable medications – used when prolonged and stable action is needed;
• subcutaneous implants – provide gradual hormone release over an extended period;
• testosterone therapy – used for male hypogonadism and some age-related changes;
• combined schemes – used to reduce the risk of endometrial hyperplasia in women with an intact uterus.

The choice of therapy form depends on the patient’s age, hormonal profile, comorbidities, and tolerance to medications.

Nutrition During Hormone Replacement Therapy

The diet during hormone therapy should support stable metabolism and provide the body with necessary macro- and micronutrients. Special attention is given to proteins, minerals, and vitamins that are involved in maintaining bone and muscle tissues:

• sufficient protein intake – usually in the range of 1.2–2.0 g per kg of body weight;
• sources of quality fats – fatty fish, butter, eggs, olive oil;
• maintaining vitamin D levels – an important regulator of bone metabolism;
• adequate calcium and magnesium intake;
• controlling sugar and refined carbohydrate intake;
• ensuring sufficient levels of trace elements, including zinc and selenium.

This nutritional strategy helps maintain stable energy balance, reduces the risk of muscle mass loss, and contributes to preserving bone density.

Features for a Ketogenic Diet

A ketogenic diet can be used as a tool for stabilizing metabolism in the context of hormonal changes. Low carbohydrate intake helps reduce fluctuations in glucose and insulin levels, which can positively affect energy levels and weight control.

The main principles of nutrition when combining a keto diet with hormone therapy include:

• limiting carbohydrates usually to 20–50 g of net carbohydrates per day;
• sufficient protein intake to maintain muscle mass;
• using natural fat sources as the main energy source;
• monitoring electrolytes – sodium, potassium, and magnesium;
• maintaining adequate hydration;
• regularly consuming foods rich in trace elements and fat-soluble vitamins.

It should be noted that the response to a ketogenic diet in the context of hormonal changes can be individual. Some people experience improved well-being and weight stabilization, while others may require a more gradual adaptation.

Monitoring Condition During Therapy

Conducting HRT requires regular medical monitoring and assessment of metabolic indicators. This allows for timely adjustments of medication dosages and nutrition:

1. assessment of hormonal status and overall health;
2. analysis of dietary intake and physical activity levels;
3. monitoring body weight and body composition;
4. monitoring biochemical blood indicators;
5. adjusting nutrition and supplements as needed.

A comprehensive approach that includes medical supervision, rational nutrition, and maintaining physical activity helps reduce the risks of hormonal deficiency and improve quality of life during hormone replacement therapy.
