Diabetes insipidus occurs when the kidney cannot retain water. Symptoms of diabetes insipidus includes extreme thirst and an unusually large amount of urine. Diabetes insipidus can be caused by a lack of the antidiuretic hormone or if the kidneys do not have a response to the hormone.
Treatment for diabetes insipidus includes treating the underlying condition and taking medication. A common drug class used to treat diabetes insipidus is the vasopressins drug class.
