Hormonal testing: why, when and how to take the test
Tiredness for no reason, trouble sleeping, mood swings, excess weight or acne? Often we look for the answer in diets, cosmetics or anti-stress tips. But sometimes the source of the problem is much deeper. In the body, everything works as a coordinated mechanism, and a "disruption" in the settings at the hormone level can affect the physical and psycho-emotional state. Therefore, checking the hormonal background is not a fashionable fad, but a real tool for maintaining health.
What is hormonal balance?
Hormonal balance is a balance of biologically active substances that regulate the functioning of almost all body systems: reproductive, nervous, endocrine, cardiovascular. Even a slight shift in hormone levels can cause serious disorders - from insomnia to infertility.
When to pay attention to hormones
The need to check hormonal levels arises with the following symptoms:
unstable menstrual cycle
weight change for no apparent reason
acne in adulthood
hair loss
mood swings, anxiety, apathy
decreased libido
infertility or problems conceiving
sleep disturbance
chronic fatigue
What tests are included in the hormonal background check?
Depending on the complaints, the doctor may prescribe:
Thyroid hormones: TSH, T3, T4 — for assessing thyroid function
Sex hormones: estradiol, progesterone, testosterone, LH, FSH - if reproductive disorders are suspected
Cortisol and ACTH — to detect chronic stress, adrenal syndromes
Insulin, leptin — for metabolism control, obesity
Prolactin — for lactation disorders, headaches, cycle disorders
How to prepare for the analysis
Blood sampling is performed on an empty stomach, usually in the morning.
For 2–3 days, you should avoid stress and physical exertion.
For 24 hours - eliminate alcohol and fatty foods
In women, sex hormones are released on certain days of the cycle (indicated by the doctor)
Do not take hormonal drugs before the test (unless otherwise indicated)
Table: indicative indicators of the main hormones
| Hormone | Reference values* | Comment |
|---|---|---|
| TSH | 0.4–4.0 μIU/mL | Elevated — hypothyroidism |
| Estradiol | 15–350 pg/mL | The value depends on the phase of the cycle |
| Testosterone | 0.2–4.0 ng/ml | In women, excess is a sign of hyperandrogenism |
| Prolactin | up to 25 ng/ml | Increases during stress, pregnancy |
| Cortisol | 140–700 nmol/L | Has diurnal dynamics, increases in the morning |
*Values may vary slightly depending on the laboratory
Why it's important not to ignore symptoms
Hormonal changes are not just a matter of mood or energy. They are often a sign of serious illnesses:
polycystic ovary syndrome
hypo-/hyperthyroidism
adrenal tumors
pituitary disorders
insulin resistance
Reliable laboratory diagnostics allows you to identify the problem at an early stage and select individual treatment or lifestyle correction.
Normalizing hormonal balance is not only about restoring physical health, but also improving emotional well-being, improving quality of life, and preventing future complications. Regular hormonal testing is becoming increasingly important not only for women, but also for men - especially in today's stressful lifestyle.
