What is hypopituitarism?
Hypopituitarism is a rare disorder that’s caused when the pituitary gland is underactive. Underactivity may mean the gland doesn’t produce one or more hormones, or it doesn’t produce enough hormones. The change in hormone levels can cause a wide range of symptoms, depending on which hormone is deficient.
The pituitary gland is part of your endocrine system. It includes all the glands that produce and regulate hormones. This small gland at the base of your brain, behind your nose, influences almost every function of your body by controlling the production and release of most hormones. Pituitary hormones regulate growth, blood pressure, reproduction and many other bodily functions.
