Diabetes Insipidus
Central diabetes insipidus is usually idiopathic but may be caused by autoimmune disorders, trauma, pituitary surgery and hypoxic or ischemic encephalopathy. The condition is relatively uncommon. In diabetes insipidus, kidney dysfunction decreases its ability to conserve water. This is secondary to a deficiency in the antidiuretic hormone (ADH). The patient's symptoms will be characterized by intense thirst and excretion of large amounts of urine which are known as polydipsia and polyuria, respectively. Familial cases of diabetes insipidus are quite rare. [10]
