I spend a lot of time researching alternative therapies for diabetes. I have been a diabetic for 37 years, and feel better today than I did ten years ago.
To answer your concern, there are two things that you should check out on the alternative side:
1). Magnesium. Diabetics are almost always extemely low in the mineral. If you are in good with your doc, have their lab do a intercellular measurement of your magnesium level. I imagine it is rock bottom. Magnesium is a good place to start with the digestive problems/gas/bloating.
2). Wild Oregano. This can assist in clearing digestive problems too. It can also help with infection and other common diabetic problems.
Do your own research on these two things and I bet you will be suprised at what is written.
Hope this helps!
