What is cortisol?
Cortisol is a hormone produced in the adrenal glands and plays an essential role in various bodily functions, including metabolism and the response to stress. It is known as the "stress hormone" because its level rises in reaction to physical and emotional stress.
Why should you have cortisol tested?
Testing cortisol is useful to determine how your body manages stress or to diagnose conditions related to the adrenal glands, such as Addison's disease or Cushing's syndrome. It can also help assess adrenal function and identify possible hormonal imbalances.
What does it indicate?
The cortisol level provides an indication of stress levels, adrenal function, and may point toward certain health conditions. Normal cortisol levels suggest the body responds well to stress, while aberrant values may indicate underlying health problems.
What does a high cortisol level mean?
A high cortisol level can indicate excessive stress, Cushing's syndrome (a hormonal disorder where the adrenal glands produce too much cortisol), or other conditions affecting cortisol production. Persistently high cortisol levels can lead to various health problems, including high blood pressure, type 2 diabetes, and fatigue.
What does a low cortisol level mean?
A low cortisol level can be a sign of Addison's disease (a condition where the adrenal glands produce insufficient hormones), certain forms of adrenal insufficiency, or a reduced stress response. Symptoms of low cortisol levels can include fatigue, low blood pressure, and weight loss.
