antidiuretic hormone

Urine-reducing pituitary secretion

Antidiuretic hormone is a chemical produced in the brain that regulates water retention in the body.

It signals the kidneys to reabsorb water rather than excrete it as urine, helping maintain proper fluid balance and blood pressure.

Also called vasopressin.

Abbreviated ADH.
