Adrenal Deficiency
In people who have adrenal insufficiency, the adrenal glands stop working properly and aren't able to produce hormones which are crucial to keeping the body functioning correctly. Adrenal insufficiency has multiple causes, giving three different types of adrenal insufficiency: primary (adrenal), secondary (pituitary), and tertiary (hypothalamus). The type of adrenal insufficiency (primary, secondary or tertiary) depends on whether the problem lies in the adrenal gland or is due to impairment of the hypothalamus and pituitary gland.
