Adrenal fatigue is a term used to describe a collection of nonspecific symptoms such as body aches, fatigue, nervousness, sleep disturbances, and digestive problems. It is thought to occur when the adrenal glands, which produce important hormones such as cortisol, cannot keep up with the demands of constant stress. The concept of adrenal fatigue is controversial. Some healthcare providers do not recognize adrenal fatigue as a real medical condition. However, supporters of the diagnosis believe the adrenal glands can become overworked and unable to produce adequate levels of hormones.
Proponents of adrenal fatigue believe factors like these can drain the adrenal glands. Over time, the adrenals lose their ability to respond appropriately to acute stress.
The signs and symptoms associated with adrenal fatigue are not specific and could have many causes. That is why conventional medicine does not recognize it as a true medical condition. However, naturopathic doctors and some alternative practitioners do diagnose and treat adrenal fatigue.
There are no standard laboratory tests for adrenal fatigue. Supporters of the diagnosis may check salivary cortisol levels at different times during the day for patterns that indicate poor adrenal function. They also look holistically at lifestyle, diet, mental health, and physical symptoms.
Treatments target reducing stress, improving diet, optimizing sleep, correcting nutritional deficiencies, and supporting adrenal function with supplements if needed.
While some healthcare experts doubt whether adrenal fatigue exists as a distinct disorder, managing lifestyle factors like stress, diet and sleep leads to better health no matter the cause of symptoms. Those with concerning fatigue should be evaluated by their physician for other potential causes.
