What is Diabetes Insipidus?
Diabetes insipidus (DI) is a condition in which the body makes too much urine. Urinating too much (polyuria) can cause severe dehydration and very high sodium levels.
This condition is usually life long and treated with daily medication.
DI is not the same as the more common diabetes mellitus.
Cause
There are several causes of DI:
- DI can happen after brain surgery, injury or infection.
- It may be present at birth if the pituitary gland does not form right. (The pituitary gland, which is in the brain, makes a hormone called anti-diuretic hormone. When the pituitary gland does not form right, it cannot make enough hormones, which can cause DI).
- DI may be inherited from parents.
Symptoms
- Making large amounts of urine often
- Being thirsty all of the time, even during the nighttime
- Would rather drink than eat
- Urine may look very clear like water
- Tearless cry
- Low energy
- Dehydration − not enough fluids in your body even though you are drinking
Treatment
DI is treated by giving a medicine called DDAVP (desmopressin). Knowing your child’s pattern of drinking and urinating will help your provider know when dose changes are needed. Knowing your child’s pattern of drinking and urinating will help your provider know when dose changes are needed.
