Hi Christy, I'm sure it's hard to deal with several health issues at the same time! What I found out about diabetes insipidus is that it is not related to diabetes melitis or "sugar" diabetes as it used to be called. According to some websites, it's sometimes called "water diabetes" because the symptoms are frequent urination and thirst. For that reason, it's sometimes mistaken by DM but a blood test will tell the difference. It's a completely different illness. The little I read about it said the treatment might be further tests to confirm it. There's a Diabetes Insipidus Foundation that you can proably find on the web. Good luck!
