The most convenient treatment is taking desmopressin (the synthetic form of vasopressin, or anti diuretic hormone (ADH)). Desmopressin comes in pill form or in a nasal spray. Endocrinologists can help you determine the appropriate dosage, and once they do, DI is a fairly easy disease to manage. If you aren't taking some form of desmopressin, it's best to make sure you are well hydrated and that you aren't drinking too much or too little water.
