Question

When someone drinks a lot of water, ADH release is suppressed. Why?

Answer 1

Antidiuretic hormone (ADH) or vasopressin increases the reabsorption of water in the distal convoluted tubule, collecting tubules and collecting ducts of the nephrons in the kidneys. As a result, the reabsorption of water from the glomerular filtrate is increased. When someone drinks lots of water, requirement of absorption of water decreases, so ADH release is suppressed.
