These glands consist of two layers, which produce different hormones.

Outer part called cortex is responsible for generating steroid hormones such as cortisol, sex steroid hormones and aldosterone.

Medulla is the internal part of the adrenal gland, which releases adrenaline and noradrenaline, also known as epinephrine and norepinephrine.

Aldosterone sustains appropriate water-salt balance and helps control your blood pressure.

Cortisol (or hydrocortisone) coordinates the way your body uses fats, proteins and carbs, as well as it regulates heart function. It works together with adrenaline and noradrenaline to respond to stress, activating all defensive processes.

As everything in your body, secretion of adrenal hormones is ruled from the brain. The pituitary gland, located at its base, stimulates adrenal glands to generate sufficient amount of hormones.

When adrenal glands fail to create hormones, serious problems may occur.

Those, who believe in existence of this disorder, say that long-term exposure to stress and negative emotions, associated with elevated cortisol and adrenaline secretion, can eventually deplete the adrenal glands.

As a result, people feel extremely tired, lose ability to sleep well, shed pounds without trying and rely on stimulants like coffee.

In reality, there is no scientific evidence to prove adrenal fatigue-theory. Symptoms are so non-specific that they might be caused by wide variety of health conditions.

Proponents of this theory say that following balanced diet, reducing alcohol and tobacco consumption, avoiding processed foods is a perfect option for treating adrenal fatigue.
