Congenital Adrenal Hyperplasia (CAH) is a group of inherited disorders that affect the adrenal glands. The adrenal glands are responsible for producing hormones that regulate metabolism, the immune system, and other bodily functions. In people with CAH, the adrenal glands do not produce enough of certain hormones, such as cortisol and aldosterone. This can lead to a variety of symptoms, including abnormal sexual development, electrolyte imbalances, and other health problems. Treatment typically involves hormone replacement therapy and lifestyle modifications.
