ADH
Water retention hormone
ADH is the abbreviation for antidiuretic hormone, a hormone produced by the pituitary gland that regulates water retention in the body.
It signals the kidneys to conserve water, concentrating urine.
When ADH levels drop, the body produces more dilute urine.
Alcohol suppresses ADH, which is why drinking leads to frequent urination and dehydration.
