what effect do caffeine and alcohol have on ADH
Caffeine inhibits ADH causing the levels in the body to lower. Anti-Diuretic Hormone is released when the body wishes to conserve water. The hormone tells the kidneys to reabsorb more water which results in urine becoming concentrated.Alcohol has a similar effect which is why, when it inhibits ADH, the body no longer attempts to conserve water.DH is a hormone that is released from the posterior pituitary gland that increases water reabsorption in t â¦ he kidneys, resulting in decreased urinary output.
