Overview
The adrenal gland secretes steroid hormones such as cortisol and aldosterone. It also makes precursors that can be converted to sex steroids (androgen, estrogen). A different part of the adrenal gland makes adrenaline (epinephrine). When the glands produce more or less hormones than required by the body, disease conditions may occur.
