Tap to reveal answer

Answer

Diabetes insipidus is a condition in which an individual has an insensitivity to or a deficiency of vasopressin (ADH). This is a hormone released by the posterior pituitary that is responsible for increasing water reabsorption in the kidney. There are three types of diabetes insipidus: neurogenic DI, nephrogenic DI, and dipsogenic DI. Neurogenic DI is characterized by damage to the posterior pituitary, which results in a deficiency of vasopressin. Nephrogenic DI is characterized by the kidneys inadequately responding to vasopressin. Dipsogenic DI is characterized by the oral ingestion of excessive amount of water, which results in a suppression of vasopressin release and ultimately leads to polyuria. Diabetes mellitus type 1 results from insufficient insulin production by pancreatic beta-cells.
