SymptomsBy Mayo Clinic staff
The most common signs and symptoms of diabetes insipidus are:
- Extreme thirst
- Excretion of an excessive amount of diluted urine
Depending on the severity of the condition, urine output can range from 2 quarts (about 2 liters) a day if you have mild diabetes insipidus to 21 quarts (about 20 liters) a day if the condition is severe and if you're drinking a lot of fluids. In comparison, the average urine output for a healthy adult varies, but is in the range of 1.6 to 2.6 quarts (about 1.5 to 2.5 liters) a day.
Other signs may include needing to get up at night to urinate (nocturia) and bed-wetting.
Infants and young children who have diabetes insipidus may have the following signs and symptoms:
- Unexplained fussiness or inconsolable crying
- Unusually wet diapers
- Fever, vomiting or diarrhea
- Dry skin with cool extremities
- Delayed growth
- Weight loss
When to see a doctor
See your doctor immediately if you notice the two most common signs of diabetes insipidus: excessive urination and extreme thirst.
