When the body does not produce enough cortisol, it can lead to a condition called adrenal insufficiency, or Addison's disease. Symptoms of adrenal insufficiency can include fatigue, muscle weakness, weight loss, low blood pressure, and darkening of the skin. Other more serious symptoms of adrenal insufficiency can include dehydration, salt cravings, nausea, vomiting, diarrhea, abdominal pain, and fever.
What Causes Low Cortisol Levels?
Low cortisol levels can be caused by a variety of conditions, including pituitary gland disorders, adrenal gland disorders, autoimmune diseases, and certain medications. In some cases, low cortisol levels can be caused by a genetic disorder, such as congenital adrenal hyperplasia.
How is Low Cortisol Diagnosed?
Low cortisol levels can be diagnosed with a blood test. The blood test measures the amount of cortisol in the bloodstream. If the test results indicate a low cortisol level, further tests may be ordered to determine the cause of the low cortisol level.
How is Low Cortisol Treated?
Treatment for low cortisol levels depends on the underlying cause. In some cases, medication may be prescribed to help regulate the body's cortisol levels. In other cases, lifestyle changes may be recommended, such as reducing stress and increasing physical activity. If the underlying cause is an autoimmune disorder, immune-suppressing medications may be prescribed.
