What is the role of antidiuretic hormone

Antidiuretic hormone is mainly used to reduce the production of urine. This hormone is regulated by the hypothalamus and pituitary gland of the human body. The urine filtered by the kidneys of normal people is called raw urine. The production of raw urine is relatively large, about 180 liters per day, but 99% of the raw urine is reabsorbed by the renal tubules and collecting ducts. Therefore, the real urine is relatively small, and the concentration of this urine is affected by antidiuretic hormone. Therefore, normal people can secrete antidiuretic hormone, resulting in concentrated urine. If there is hypothalamic or pituitary disease, resulting in reduced antidiuretic hormone secretion, it will cause increased urine production. This disease is also called diabetes insipidus.
