Definition of Diabetes insipidus

1. Noun. A disease characterized by excretion of large amount of severely diluted urine, which cannot be reduced when fluid intake is reduced. It is generally related to a tumor or insult to the pituitary gland, where the hormonal signals the pituitary gives to the kidneys break down, and the kidneys do not conserve water, but express all water as urine. This is a rather rare disease. ¹

Medical Definition of Diabetes insipidus

1. Rare form of diabetes in which the kidney tubules do not reabsorb sufficient water. This can be because (a) either the renal tubules have defective receptors for antidiuretic hormone (ADH, vasopressin) or (b) a class of aquaporin water channel in the collecting duct is defective or (c) there is inadequate ADH production by the pituitary, leading to the excessive production of dilute urine.
