I am 20 years old, and have had IBS since I can remember. Alternating constipation/diarrhea, which I have learned to live with. Recently had a fissure due to constipation, which was a joy if anyone has had one they know what its like!! I have had a colonoscopy (was definately the youngest person in that place that day ha) and came back normal, drs are not helpful,etc. So my main problem (which fluctuates along with my c/d) is this almost scary bloating. I literally can go from a normal size stomach to literally looking 5 months pregnant in a second. This distention is to the point where it is disturbing..and its hard for a doctor to really see how large it gets because I can't time when it happens...it is very random. It is not extremely discomforting but if I press on it (or press on my stomach at any time for that matter) it is painful. I am a athlete and while I am not a toothpick, my stomach should NEVER get this big. Does anyone have any advice for me?? Is this totally normal?!
