What hormone does alcohol inhibits?

Alcohol inhibits the secretion of antidiuretic hormone (ADH), also known as vasopressin. This hormone is responsible for regulating water balance in the body by promoting water reabsorption in the kidneys. When alcohol consumption reduces ADH levels, it leads to increased urine production and dehydration. This is why consuming alcohol can often result in frequent urination and a hangover associated with dehydration.
