Final answer:
Diabetes insipidus is a condition characterized by decreased production of ADH, resulting in excessive water loss and symptoms like increased thirst and urine volume.
Step-by-step explanation:
Diabetes insipidus is a condition characterized by decreased production of antidiuretic hormone (ADH) or decreased sensitivity to ADH. ADH is responsible for regulating water balance in the body by promoting water reabsorption in the kidneys. When there is a deficiency of ADH, excessive water loss occurs through excessive urine output, leading to symptoms such as excessive thirst and excessive urine volume.
