What Can Cause Stomach Bloating?

Hmmm well if you have Diabetes- I know you have to control your diet to include and exclude certain foods.  Make sure you're eating enough even if you can't eaten certain foods.  Sometimes lack of food causes stomach bloating.  Are you taking any new medicines?  It could be from an allergic reaction.  Other than that, I don't know much about your situation.  I hope everything turns out ok.  My prayers are with you!
