Adrenal fatigue is not a straightforward diagnosis; its symptoms are nonspecific, and the condition is not well defined or researched. Though a topic of frequent discussion in alternative medicine, the condition is not accepted by many conventional medicine physicians due to the lack of reliable and conclusive research. That said, supporters of the diagnosis believe symptoms develop when the adrenal glands are stressed and cannot produce the necessary amount of hormones required to keep the body functioning normally. These slight changes have huge effects on the body but are difficult to detect with diagnostic testing.


1. Low Energy

Cortisol is one of the essential hormones produced by the adrenal glands; it plays several important roles, including converting sugar and fat into energy. If the adrenal gland produces an insufficient amount of cortisol, fatigue can result. Low energy is often one of the first signs of adrenal fatigue and can manifest in a variety of ways, including difficulty carrying out physical activities and muscle weakness that affects one's ability to perform strenuous actions or even walk.
