Diabetes insipidus is a condition caused by not enough antidiuretic hormone (ADH) in the body. ADH is also known as vasopressin. This is a hormone that helps the kidneys keep the correct amount of water in the body. The condition is also called “water diabetes.”
ADH controls how much water is in urine that the kidneys make. ADH is secreted by a small gland at the base of the brain called the hypothalamus. It’s stored in the pituitary gland, and then released into the bloodstream when needed. ADH lowers the amount of water the kidneys make into urine. This helps prevent dehydration.

Your child must also drink plenty of fluids. This is to make up for the amount of fluids lost by the body through excess urine. You may need to watch your child’s fluid intake and urine output.
