I have had excessive gas for a long time. i would eat even a tiny fruit and i would feel gassy. i tried to solve it this year by drinking lime with water first thing in the morning and not eating after that until i come home from school. what's wrong?

Causes of excessive: upper intestinal gas include swallowing more than a usual amount of air, overeating, smoking, chewing gum. Excess lower GI gas can be caused by lactose OR fructose intolerance, eating gas causing foods (beans, lentils, cruciferous veggies--cabbage, broccoli, etc), carbonated beverages. Diseases can cause: celiac, Crohn's, GERD, inflammatory bowel disease. Full GI work-up should clarify. Good luck
