    3 per 100,000 per year [4] Diabetes insipidus (DI) is a condition characterized by large amounts of dilute urine and increased thirst. [1] The amount of urine produced can be nearly 20 liters per day. [1] Reduction of fluid has little effect on the concentration of the urine. [1] Complications may include dehydration or seizures.

    Nephrogenic diabetes insipidus, recently renamed arginine vasopressin resistance (AVP-R) and previously known as renal diabetes insipidus, is a form of diabetes insipidus primarily due to pathology of the kidney. This is in contrast to central or neurogenic diabetes insipidus, which is caused by insufficient levels of vasopressin (also called ...
