Diabetes insipidus is caused by problems with a hormone called vasopressin (AVP), also called antidiuretic hormone (ADH). AVP plays a key role in regulating the amount of fluid in the body. It's produced by specialist nerve cells in a part of the brain known as the hypothalamus.
A hormone known as antidiuretic hormone (ADH) — also called vasopressin — is needed to get the fluid that's filtered by the kidneys back into the bloodstream. ADH is made in a part of the brain called the hypothalamus. It's then stored in the pituitary gland, a small gland found at the base of the brain.
