Testing Your Cortisol Levels

Cortisol, often referred to as the “stress hormone,” plays a vital role in regulating various functions within the body, including metabolism, immune response, and blood sugar levels. A cortisol blood test helps assess the levels of this hormone in your bloodstream, offering valuable insights into your adrenal gland function and overall health.

Why It Matters

A cortisol blood test is recommended to:

  • Diagnose conditions such as Cushing’s syndrome (high cortisol levels) or Addison’s disease (low cortisol levels).
  • Investigate symptoms such as fatigue, weight loss or gain, low blood pressure, or muscle weakness.
  • Monitor adrenal gland function and the effectiveness of treatments for related disorders.

What Do Your Cortisol Results Mean?

High cortisol levels may indicate Cushing’s syndrome, stress or anxiety tumours of the adrenal or pituitary glands. Low cortisol levels may suggest Addison’s disease, or hypopituitarism (reduced function of the pituitary gland). Your doctor will interpret the results in the context of your symptoms and medical history and may recommend further tests if needed.

Who Should Consider a Cortisol Blood Test?

  • Struggle with unexplained fatigue or persistent low energy.
  • Experience sudden weight changes without a clear cause.

What is cortisol?
Cortisol is a hormone. The adrenal glands produce it and is important for helping regulate metabolism, immune response, and the body’s stress response. A cortisol blood test measures the level of cortisol in your blood.
What do high cortisol levels mean?
Elevated cortisol levels may indicate Cushing’s syndrome, stress, or obesity. It may also indicate conditions like a pituitary gland tumour or adrenal gland disorder. Low cortisol levels, on the other hand, could be a sign of Addison’s disease, adrenal insufficiency, or a pituitary gland disorder.
When is the best time to take a cortisol blood test?
In general, cortisol levels naturally vary throughout the day. They tend to peak in the morning and decline at night. A cortisol test is usually done in the morning. Your doctor may ask you to avoid eating or drinking anything other than water for a few hours before the test. You may also need to avoid certain medications that can affect cortisol levels.
