Less urine is produced.


The name of the hormone already gives away the answer: anti diuretic hormone (ADH) means against urine flow.

The hormone ADH (also called vasopressin) is produced by the hypothalamus and stimulates water resorption by the kidneys (concentration of urine). This way the body balances the amount of fluid in the body.

  • high levels of ADH : less urine is produced, urine is very concentrated.
  • low levels of ADH : more urine is produced, urine is strongly diluted.
