Stress and hormonal balance: what tests will help detect disorders

Why it is important to study hormones in chronic stress

Stress activates the hypothalamic-pituitary-adrenal axis, which affects most hormonal systems. Disturbances can manifest as symptoms that are difficult to associate with endocrinology: fatigue, insomnia, weight change, decreased libido, cycle or skin problems.

In such cases hormonal tests help not only to identify imbalances, but also distinguish physiological stress from pathological changes.

Key hormones that respond to stress

1. Cortisol

The most indicative marker of stress. Normally it has diurnal rhythm — higher in the morning, lower in the evening.
Research methods:
– serum cortisol (morning and evening sample)
– cortisol in saliva (convenient and non-invasive option)
– daily urinary cortisol excretion

2. DHEA-S (dehydroepiandrosterone sulfate)

Cortisol antagonist. Its levels decrease with chronic stress.
Blood test allows you to assess adrenal reserves.

3. TSH (thyroid stimulating hormone)

Hypothyroidism is often the result of long-term emotional overload.
Research methods:
– TSH, free T4, free T3 — comprehensive assessment of thyroid function

4. Prolactin

Increases in response to stress. Often associated with menstrual irregularities, headaches, and infertility.
Prolactin analysis It is necessary to take into account your emotional state, since even slight excitement before blood sampling can increase the level.

5. Insulin and glucose

Constant exposure to cortisol causes insulin resistance.
Recommended tests:
– fasting glucose
– insulin
– HOMA-IR (insulin resistance index)

6. Sex hormones

In women: estradiol, progesterone, LH, FSH
In men: total and free testosterone, LH
These indicators decrease with chronic stress. and impair fertility and libido.

Additional research methods

Diurnal cortisol curve

Measuring cortisol at different times (e.g. 8:00 AM, 2:00 PM, 8:00 PM) allows us to assess stress response in dynamics. Used in complex clinical cases.

Functional tests

– Dexamethasone test (cortisol suppression assessment)
– Exercise test (e.g., glucose tolerance test) — important when metabolic disorders are suspected

Integral panels

Modern laboratories offer comprehensive stress assessment panels, which include cortisol, DHEA, melatonin, sex hormones, and sometimes C-reactive protein and interleukins.

How to prepare for hormone tests

• Surrender in the morning on an empty stomach

• Avoid exercise, alcohol, and caffeine for 24 hours

• Before submission sit for 15 minutes in a calm state

• In women, consider the phase of the cycle (for sex hormones)

When to get diagnosed

• Chronic fatigue, especially after rest

• Menstrual cycle disorders, infertility

• Mood swings, anxiety, panic attacks

• Weight fluctuations without diet changes

• Hair loss, dry skin, insomnia

• Persistent fat gain in the abdominal area

Hormonal balance is a precise system that responds to every stimulus. That's why Correct laboratory diagnostics are the basis for restoring physiological balance. after stress.
