ADH stands for antidiuretic hormone also known as vasopressin. ADH primarily acts in the kidney to resorb water. Vasopressin can also be administered to raise blood pressure. ADH is produced by the hypothalamus and released into the bloodstream by the pituitary gland. ADH levels increase in response to low blood volume. Thus in times of dehydration or hemorrhage, ADH works to increase the amount of water in the bloodstream by decreasing water loss and kidney. This increased water retention will also dilute the amount of sodium in the blood, causing sodium levels to decrease. On the other hand, the pituitary stops releasing ADH in response to decreased sodium levels in the blood, acting as a feedback mechanism.
Normal Ranges for ADH:
1 to 5 pg/mL
