Cortisol

What is Cortisol?

Cortisol, also known as hydrocortisone, is the primary glucocorticoid hormone produced by the adrenal cortex. It plays a crucial role in regulating a wide range of essential physiological functions, including energy metabolism, immune response, blood pressure regulation, and the body’s response to stress.

Diagnostic Importance of Cortisol Testing

Cortisol level testing is vital in diagnosing several adrenal-related conditions, including:

Cushing’s syndrome – caused by excessive cortisol production

Addison’s disease – characterised by adrenal insufficiency and low cortisol output

Monitoring hormone therapies such as the dexamethasone suppression test or cortisol replacement therapy

Effects of Cortisol on the Body

Cortisol influences numerous bodily functions, including:

Glucose and fat metabolism

Electrolyte balance and blood pressure stability

Immune system modulation

Cellular repair and proliferation

Cognitive and emotional stability

Conditions Associated with High Cortisol Levels

Elevated cortisol levels can occur as a response to:

Chronic stress

Psychiatric disorders

Obesity

Diabetes

Alcoholism

Pregnancy

These elevations can complicate the diagnosis of conditions like Cushing’s syndrome, as similar hormonal patterns may be observed in other health issues.

Conditions Linked to Low Cortisol Levels

Low cortisol levels may be found in:

Adrenal enzyme deficiencies

Chronic adrenal exhaustion after prolonged stress or illness

Addison’s disease and related endocrine disorders
