Too little or no water is reabsorbed at the renal tubule and the collecting duct

Detailed explanation-1: -In a healthy person, AVP acts as a signal to the nephrons to reabsorb water into the body. In nephrogenic diabetes insipidus, the nephrons in the kidneys are not able to respond to this signal, leading to excessive water loss in large amounts of urine.
Detailed explanation-2: -In rare cases, the kidneys do not respond to AVP. This causes a specific form of diabetes insipidus called nephrogenic diabetes insipidus. People feel thirsty as the body tries to compensate for the increased loss of water by increasing the amount of water taken in.
Detailed explanation-3: -Diabetes insipidus (die-uh-BEE-teze in-SIP-uh-dus) is an uncommon disorder that causes an imbalance of fluids in the body. This imbalance leads you to produce large amounts of urine. It also makes you very thirsty even if you have something to drink.
Detailed explanation-4: -Diabetes insipidus happens when your body doesn’t make enough antidiuretic hormone (ADH) or your kidneys don’t use it properly. Your body needs ADH to retain appropriate amounts of water. Without ADH, your body loses water through urine.
