Hypopituitarism is a rare disorder in which your pituitary gland either fails to produce one or more of its hormones or doesn't produce enough of them.
The pituitary is a small bean-shaped gland situated at the base of your brain, behind your nose and between your ears. Despite its size, this gland secretes hormones that influence nearly every part of your body.
In hypopituitarism, you have a short supply of one or more of these pituitary hormones. This deficiency can affect any number of your body's routine functions, such as growth, blood pressure and reproduction.
You'll likely need medications for the rest of your life to treat hypopituitarism, but your symptoms can be controlled.
