The absence of anti-diuretic hormone in humans results in

The absence of anti-diuretic hormone (ADH) in humans results in increasing dehydration. ADH is a hormone produced by the pituitary gland in the brain that helps regulate the body's water balance by controlling the amount of water that is reabsorbed by the kidneys. When ADH is absent, the kidneys do not reabsorb enough water from the urine, which leads to an increase in urine output and a decrease in the amount of water in the body. As a result, the body becomes dehydrated, which can lead to symptoms such as thirst, dry mouth, fatigue, and dizziness. So, in summary, the absence of ADH in humans results in increasing dehydration, as the kidneys excrete too much water, leading to a decrease in the overall amount of water in the body.
