What is congenital adrenal hyperplasia?
Congenital adrenal hyperplasia, or CAH, is a disorder that affects the adrenal glands. The adrenal glands produce hormones, including sex hormones and cortisol and aldosterone. A person who has CAH doesn't make enough of the hormones cortisol and aldosterone, and makes too much androgen, which is a male sex hormone.
CAH is usually diagnosed at birth or in early childhood. Both boys and girls can have CAH.
