Enuresis, or bedwetting, may be caused by psychological, anatomical or physiological factors. In the latter case, vasopressin is often prescribed and is a very effective treatment. What is vasopressin? How can it prevent enuresis?
What will be an ideal response
Vasopressin is also called antidiuretic hormone or ADH. In addition to its vasoconstrictive effects, ADH causes the kidneys to reabsorb more water. Someone who does not make enough ADH may not be able to contain all of the urine produced while they are sleeping. If they are not awakened by the pressure in their urinary bladder, they may wet the bed instead of getting up and going to the toilet. Since vasopressin helps the body reabsorb more water, a person's bladder should not get so full that they end up wetting the bed while sleeping.
