A person has very little thirst, dry mouth. If he drinks water, the water is coming out through the urine, but his body lacks water. Why does this happen and what is the remedy?
Generally, in central diabetes insipidus (the most common), the problem lies with the pituitary gland, which fails to produce or release sufficient amounts of antidiuretic hormone (ADH), also known as vasopressin. Antidiuretic hormone helps regulate water balance by controlling the amount of water that is reabsorbed by the kidneys. Without enough antidiuretic hormone, the kidneys cannot retain water effectively.
