Welcome to Health Care Magic. Thank you for posting your question. I can understand your concern. I went through the details. Abdominal bloating can be due to : constipation heartburn irritable bowel syndrome intolerance to dairy products overgrowth of bacteria in the small bo giardiasis (intestinal parasites) sugar substitutes (fructose and sorbitol) fluid in the abdominal cavity (ascites) as a result of abdominal tuberculosis, liver disease, kidney failure, congestive heart failure, liver cancer and other disorders pancreatic insufficiency (impaired digestion because the pancreas cannot produce enough digestive enzymes) Don t worry much, I would suggest you to take some measures like Limit your intake of carbonated drinks. Avoid “gassy” foods, such vegetables in the cabbage family, dried beans, and lentils. Eat slowly. Use lactose-free dairy products. Yes abdominal CT can be a option to pick up abdominal tuberculosis and strictures . But let the decision be taken by the doctor. Barium enema has ruled out diverticuli. I would suggest you to visit a gastroenterologist . He/she can examine you and correlate clinically and guide you on the further management. Hope this helps. Post any other question. We will be happy to help. Have a nice day. Regards.
