Central Diabetes Insipidus
What is central diabetes insipidus?
Central diabetes insipidus is not having enough of a hormone called vasopressin. Hormones are chemicals that stimulate other cells or tissues into action. Vasopressin is a hormone that signals your kidneys to make less urine so your body retains water. Vasopressin is made in part of your brain called the hypothalamus, and then it's stored and released from your pituitary gland. The hypothalamus and pituitary are both located at the bottom of your brain.
