What is a Cortisol Test?

Cortisol is often referred to as the stress hormone because of its role in the body’s stress response. As your body reacts to stress it releases the hormone cortisol into your bloodstream via your adrenal glands. A blood sample is used to analyse the levels of cortisol in the body.

Why consider a cortisol test?

If you are feeling particularly anxious, stressed or irritable then you should consider a cortisol test. When you are under constant stress, your body can experience long-term exposure to cortisol and other stress hormones, increasing your risk of many health issues including heart disease, obesity, anxiety and depressions.

Cortisol levels can also be used to diagnose potential disorders of the adrenal glands which can develop into more serious conditions. For example, Cushing’s syndrome can be caused by an over production of cortisol whereas Addison’s disease is the underproduction.

Symptoms of excessive Cortisol can include:

  • Obesity, mainly around the torso
  • High blood sugar
  • High blood pressure
  • Red and swollen face
  • Muscle weakness

Symptoms of low levels of Cortisol can include:

  • Weight loss and loss of appetite
  • Fatigue
  • Muscle weakness
  • Low blood pressure
  • Nausea and vomiting
