DIABETES INSIPIDUS
What Is Diabetes Insipidus?
Diabetes Insipidus (DI) is a rare condition that makes your body lose too much water through your urine. It is not the same as diabetes mellitus, the one that affects blood sugar. Instead, DI affects how your body controls water.
What Causes Diabetes Insipidus?
Diabetes Insipidus happens when the body doesn’t make enough of a hormone called vasopressin, or when the kidneys don’t respond to this hormone. Vasopressin helps the body hold on to water.
Causes include:
Damage to the brain (from surgery, injury, or tumor)
Problems with the pituitary gland
Certain medications
Genetic conditions (from birth)
Signs and Symptoms
Peeing a lot (even at night)
Always feeling very thirsty
Dry mouth
Weakness or tiredness
Dehydration (dry skin, dizziness, confusion)
Headaches
Treatment
Treatment depends on the type of DI. Some common treatments include:
Desmopressin (DDAVP): A medicine that replaces the missing hormone.
Drinking enough water: To avoid getting dehydrated.
Treating the cause: Like stopping a certain medicine or treating a brain injury.
Always take your medicine exactly as the doctor tells you.
Special Diet
Drink water often during the day.
Avoid drinks with caffeine (like coffee and soda) as they can make you pee more.
Your doctor may tell you to limit salt or follow a low-sodium diet to reduce urine output.
Special Precautions and Considerations
Do not skip your medicine.
Always carry water with you.
Let your doctor know if you are urinating more than usual or feeling very thirsty.
Avoid becoming dehydrated, especially in hot weather or when you are sick.
Wear a medical ID bracelet so others know you have DI in an emergency.
Be cautious with over-the-counter medications. Ask your doctor before using any new medication.
