Living with Non-acquired combined pituitary hormone deficiency

A group of genetic conditions in which the pituitary gland doesn't make enough of several hormones, affecting growth and puberty.

Understanding Non-acquired combined pituitary hormone deficiency

Non-acquired combined pituitary hormone deficiency is a group of genetic conditions in which the pituitary gland does not make enough of several hormones.

It is an endocrine (hormone) condition. The pituitary gland may not develop or work normally, causing low levels of hormones for growth, metabolism, breastmilk production, stress response, and reproduction. It can also affect thinking and delay puberty. Symptoms can begin at any time in life.
