Diabetes insipidus is a condition characterized by excessive thirst and increased urine output. It occurs due to decreased production of antidiuretic hormone (ADH) by the posterior pituitary gland. ADH helps to regulate water balance in the body by reducing the amount of water lost in the urine. When there is a deficiency of ADH, the kidneys cannot retain enough water, leading to excessive urination and thirst.
