ADH (Antidiuretic Hormone) The brain and kidneys regulate the amount of water excreted by the body. When the blood volume is low, the concentration of solutes in the blood is high. When the hypothalamus senses this low blood volume and increased serum osmolality it synthesizes ADH, a small peptide molecule.
Alcohol consumption inhibits the secretion of ADH and results in  increased urine output that can disrupt the body's fluid balance. In a nutshell, Antidiuretic hormone (ADH) causes the kidneys to retain water instead of excreting it. In your case, because the amount of ADH is increased, the amount of â¦ water retained in the body is also increased. The increased water enters blood vessels and increases blood pressure.
