This hormone plays a crucial role in maintaining water balance in the body. When the body is dehydrated, specialized detectors sense the increased salt concentration and decreased water volume. In response, they send a signal to the posterior pituitary gland, stimulating the release of ADH.
Not only does alcohol impair the absorption of nutrients, but it also affects their storage and use within the body.
