Overactive Adrenal Glands in Children
What are overactive adrenal glands?
Adrenal glands make a series of hormones. The hormones are androgens, corticosteroids,
and aldosterone. Overactive adrenal glands make too much of one or more of these hormones.
This can cause health problems. The health problems vary depending on which hormones
are in excess. For example, too much aldosterone can caused high blood pressure and
low levels of potassium.

of the body. A CT scan shows images of any part of the body, including the bones,
muscles, fat, and organs.

of the inside of the body.
