Certain factors may prevent the release of ADH, these include alcohol consumption, diabetes insipidus, or a tumor in the pituitary glands. Such conditions can cause low levels of ADH in the blood.
The anti-diuretic hormone acts to maintain blood pressure, blood volume, and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney.
ADH is produced by the hypothalamus and then released by the pituitary gland in the brain.
The kidneys will secrete too much water because of low anti-diuretic hormone levels. Dehydration and a drop in blood pressure will result from an increase in urine output.
A deficiency of antidiuretic hormone (ADH), also known as vasopressin, which prevents dehydration, or the kidney's failure to react to ADH, are the two main causes of diabetes insipidus.
