Had recurring upper GI pain for about two years. Went to doc and got scan. Found I had gall stones and proceeded to have GB removed. Since then have had mild upper GI pain, nothing too serious but recently went back to the Doc (3 years after op) because of worsening pain. He suggested a fiber supplement as he thought it was more intestinal then Liver, tried it for a month with very little effect. Decided myself to eliminate all foods from my diet for two days and reintroduce one at a time. Any foods containing gluten would result in immediate reaction, bloating, pain, constipation etc and re-eliminating them would resolve the issue. I believe I am a celiac and Gall stones were a result of undiagnosed celiac disease.
