What is Diabetes Insipidus?
Diabetes insipidus (DI) is a rare condition that affects the body's water balance, causing excessive thirst and urination. Despite sharing part of its name with diabetes mellitus, these conditions are unrelated.
Types of Diabetes Insipidus
-
Central DI
- Caused by insufficient vasopressin (ADH) production
- Usually results from damage to the hypothalamus or pituitary gland
-
Nephrogenic DI
- Results from kidney resistance to vasopressin
- Can be inherited or caused by medications
Common Symptoms
- Extreme thirst (polydipsia)
- Frequent urination (polyuria)
- Production of large amounts of dilute urine
- Dehydration if fluid intake is restricted
- Disrupted sleep due to frequent urination
Diagnosis
- Water deprivation test
- Urine and blood tests
- MRI of the brain (for central DI)
- Genetic testing (for inherited forms)
Treatment Options
For Central DI:
- Desmopressin (DDAVP) - synthetic vasopressin
- Available as nasal spray, tablets, or injections
For Nephrogenic DI:
- Dietary salt restriction
- Diuretics (in some cases)
- Treatment of underlying conditions
Living with Diabetes Insipidus
- Maintain adequate fluid intake
- Regular medical monitoring
- Wear medical identification
- Monitor urine color and output
When to Seek Medical Care
- Severe dehydration symptoms
- Mental confusion
- Rapid heart rate
- Extreme fatigue
- Unexplained weight loss
Prevention of Complications

Long-term Outlook
