Adrenal fatigue is a term used to describe supposed mild dysfunction of the adrenal glands. The adrenal glands produce key hormones, including cortisol and adrenaline, that help regulate metabolism, immune function, blood pressure, and other essential processes. Some healthcare practitioners claim adrenal fatigue is an under-recognized condition caused by chronic stress. Symptoms may include:
- Fatigue
- Difficulty coping with stress
- Body aches
- Disrupted sleep
- Low blood pressure
- There is no standard test or consistent biomarkers to diagnose adrenal fatigue. Blood, saliva or urine tests for adrenal hormones tend to be normal, even in people with symptoms.
- The proposed symptoms are common and nonspecific, with many potential causes. They overlap with other conditions like depression, thyroid disorders, and sleep apnea.
- There are few high-quality research studies on adrenal fatigue specifically. The underlying theories lack robust scientific evidence.
