I struggled with that as well. I was told rny would reverse the diabetes in hours (in most cases) and that I could reverse it with the sleeve but it would take a while and come through weight loss. I decided I was ok with it taking a little while, as the rny just scares me too much!
I'm diabetic. In the year before surgery I dropped my a1c from 8.9 to 5.5. Perfect! But still had high fasting numbers and if I ate carbs my numbers would jump. I'm happy to report that since surgery my numbers have been fantastic!
Newly sleeved. Lost 10 the first week, only two the next week and two the week after. I was supposed to take vit d, calcium and b12 the next day but had to wait until 3 weeks to start on a daily vitamin and b complex.
