Treatment:

The cause of the underlying condition should be treated.

Vasopressin (desmopressin) will be given either as a nasal spray, tablets by mouth, or injections under the skin. This controls the urine output and fluid balance and prevents dehydration.

In mild cases, drinking more water may be all that is needed. If the thirst mechanism is not working (for example, if the hypothalamus is damaged), a prescription for a certain amount of water intake may also be needed (usually 2-2.5 L per day) to ensure proper hydration.

Expectations (prognosis):

The outcome depends on the underlying disorder. If treated, diabetes insipidus does not cause severe problems or result in early death.

Complications:

• Dehydration
• Electrolyte imbalance
• Confusion and changes in mental status may develop if the condition is not treated.

All patients with diabetes insipidus should wear a medic alert bracelet or necklace to alert care givers to this condition in an emergency situation.

Calling your health care provider:

Call your health care provider if symptoms indicate diabetes insipidus may be present.
