I just found out 2 weeks ago that I was Type 2. I was at my last appointment and was meeting with the anesthesiologist and he said that my pre op testing revealed my sugars were up so my surgery has been on hold until everything levels out. They have told me that the symptoms of diabetes will most likely be gone, and any meds will likely be discontinued as well. So, I'm thinking you may be in luck with the surgery!!
I'm to the point where I eat a little different than the diet right after surgery, so I don't experience a lot of lows...my blood sugar is pretty consistent. I'm also pregnant, so I am able to eat more carbs now.
However, I have had lows and I can very much feel them. My hunger sensation never came back, so I have to remember to eat usually, and if I forget (never thought that would happen!) I get a headache and if it goes too long, I'll go into a sugar low with the shakes and that fuzzy feeling in the brain.
I was Type 2 Diabetic and couldn't lose the weight. After having RNY I started my medications and crashed...after that I never took any more meds again however...now I'm hypoglycemic... sometimes which I think it's worst...lol....ooh well ............but I did get "rid" of it to some degree. Depending on your type and history you may or may not. Your doctor or surgeon can best answer that question.
