Doctor's typically use a variety of tests to diagnose adrenal fatigue. These tests may include a complete physical exam, a review of medical history, and laboratory tests, such as 24-hour cortisol and/or DHEA levels, a saliva test, and an ACTH stimulation test.
During the physical exam, a doctor will look for signs of adrenal insufficiency, such as low blood pressure, low blood sugar, and pale skin. They will also measure your weight, BMI, and waist circumference to look for signs of obesity or malnutrition.
The doctor will also discuss your medical history, looking for signs of physical, mental, emotional, or environmental stress, as well as signs of diabetes or other chronic illnesses.
In order to confirm a diagnosis of adrenal fatigue, the doctor may take a blood sample to measure the levels of cortisol and DHEA in the body. Cortisol is a hormone that is released by the adrenal glands in response to stress or illness, while DHEA is a hormone that helps regulate mood, energy levels, and metabolism. A low level of either hormone can indicate adrenal fatigue.
The doctor may also request a saliva test to measure cortisol levels at different times of day. This helps to assess the body's cortisol rhythm.
The ACTH stimulation test is another test that may be used to diagnose adrenal fatigue. This test measures the body's response to ACTH, a hormone released by the pituitary gland that stimulates the adrenal glands to release cortisol. If the body does not produce an adequate amount of cortisol in response to ACTH, it could be a sign of adrenal fatigue.
Once the diagnosis of adrenal fatigue is confirmed, the doctor may recommend lifestyle changes, dietary modifications, and/or supplementation to help restore adrenal health.
