Adrenal insufficiency is characterized by the inadequate production of cortisol by the adrenal glands. Cortisol is a crucial hormone that helps the body respond to stress, regulate metabolism, and maintain blood pressure, among other functions. When the adrenal glands fail to produce sufficient levels of this hormone, it can lead to various symptoms, including fatigue, weakness, weight loss, low blood pressure, and a craving for salt.

Understanding adrenal insufficiency involves recognizing its difference from other conditions related to cortisol levels. For instance, while excess cortisol production leads to conditions such as Cushing's syndrome, adrenal insufficiency specifically refers to the lack of production. This distinction is vital for diagnosing and managing patients effectively, as the treatment approaches for adrenal insufficiency differ significantly from those for conditions associated with excess cortisol. Thus, the correct definition emphasizes the adrenal glands' failure to produce adequate cortisol, which is crucial for maintaining many bodily functions.
