Cortisol Test

Cortisol test, also known as serum cortisol test, is a simple blood test that is used to find out the amount of cortisol in the blood. The cortisol blood test is also used to diagnose Addison’s disease or Cushing Syndrome. It is also used to assess the functioning of the adrenal glands and the pituitary gland in the brain.

What is cortisol?

Cortisol hormone, popularly referred to as stress hormone, is a steroid hormone that is produced by the adrenal glands on top of each kidney. Cortisol is mainly released in response to stress and low blood glucose concentration. The Cortisol hormone is part of the glucocorticoid class of hormones. The amount of cortisol in the body depends on a person’s eating habits and the amount of his physical activities. Cortisol levels are at their highest level in the morning, which drops to the lowest level by evening.

What are the functions of cortisol?

Cortisol is a steroid-based hormone and is a strong chemical that changes the gene activity in the DNA. It prompts the cells to produce glucose from proteins and fatty acids, a process known as gluconeogenesis. This saves the glucose for the brain, forcing the body to use fatty acids from the stored fat as energy. Some of its primary functions include the following;

  • Cortisol hormone manages how the body utilities carbohydrates, protein and fats in the body.
  • It also helps in keeping inflammation down
  • Regulates blood pressure
  • Increases blood sugar or glucose
  • Controls the sleep and wake-up cycle
  • Cortisol gives an energy boost to deal with stress and restores balance later.

The hypothalamus and pituitary gland in the blood sense the volume of cortisol levels in the blood; if the cortisol level is too low, then it adjusts the amount of hormones made. The adrenal glands pick up on the signals and then balance the amount of cortisol in the blood.

The daily requirement for cortisol in the blood varies. For instance, when the body is on high alert, the cortisol hormone will alter or shut down the function that comes in its way, including the digestive system, immune system and the growth process.

Too little of cortisol levels or cortisol deficiency can lead to a health condition called Addison’s disease. The major symptoms of Addison’s disease are as follows;

  • Persistent tiredness
  • Changes in skin and darkening of the scars and skin folds
  • Muscle weakness
  • Diarrhea, nausea and vomiting
  • Low blood pressure
  • Loss of appetite and weight

Too much of cortisol can lead to Cushing’s syndrome; the major symptoms are as follows;

  • Rapid weight gain
  • Easy bruising of the skin
  • Muscle weakness
  • Diabetes

Why is the cortisol test advised?

Cortisol blood test is mainly given to a person to measure their cortisol levels if they are showing the following symptoms;

  • Anxiety and depression
  • Headaches
  • Heart disease
  • Memory problems and difficulty concentrating
  • Digestion problems
  • Trouble falling asleep
  • Weight gain or unintended weight loss
  • Fatigue
  • Muscle weakness
  • Low blood pressure
What are causes of cortisol deficiency?

The major cause of cortisol deficiency is the adrenal gland’s failure to produce levels of cortisol or adrenal insufficiency; this may be caused because of adrenal glands disorder or the inadequate secretion of the ACTH by the pituitary gland. Few of the health conditions responsible for the low levels of cortisol are TB, autoimmune disorders, fungal infections, surgical removal of the adrenal glands, etc.

Causes of high cortisol levels

High cortisol levels are primarily the overproduction of the stress hormone; high cortisol levels could be because of varied reasons like adrenal gland disorders, constant stress, pituitary gland tumours, pregnancy, liver or kidney disease, hyperthyroidism, etc. The main High cortisol levels symptoms are; breast growth in men, impotence, acne and abnormal menstrual periods in women.

High cortisol level treatment involves medications to reduce the cortisol production or block the effect of cortisol on tissues. Besides medications, one can also adopt some natural remedies to reduce cortisol like;

  • Including whole food and anti- inflammatory diet
  • Reduce and manage stress
  • Meditate
  • Acupuncture
  • Deep breathing exercises
