If you haven't changed your diet, you haven't added meds or changed meds, or if you weren't sick before this happened, you may want to consider checking with your doc and asking for some stool tests to see if you might have picked up some type of unwanted 'critter' that might be causing the problem. In the meantime, you might may want to take dairy out of your diet to see if that's on any help.
You might also want to start keeping a food diary to see if there are any foods or food groups that make things better or worse.
I completely know how u feel. I have gas problems too and can't control it. it just happens, sometimes i dont even feel it. im only 16 and have to deal with this problem through high school. is soo embarrassing. i've had a endoscopy, taken meds, and done stool samples sent for testing too. seems like everything is "normal" but why can't i find a solution for the bloating and passing gas?
PLEASE if you find something that helps PLEASE tell me. ANYTHING. =(
