Hi welcome to HCM.. According to your history .... Provisional diagnosis : functional bowel disease .... (Irritable bowel syndrome has to be ruled out by detail clinical history ) Here for functional bowel disease you are taking rabeprazole ... Plus if needed fiber supplement also can be given .... Try to drink two to three litre water daily .. More exercise .... Fruits taken more ... Whole grain , wheat bran , apple , avocados , beet roots taken more ... Gas forming food avoided like ... -turnip -onion -cabbage -cauliflower etc... If abdominal pain associated and alternate diarrhea and constipation there IBS can be cause . For that avoid stress ... Specific drug available for it like lubiprostone .... If no improvement USG abdomen done .... Advise : if needed gastroenterologist consultation.... Take care ...
