I seem to have an indigestion problem, my stomach keeps bloating though there's no pain or any other problem. I've been treated by a gastroenterologist after blood test, stool test, sonography and even an endoscopy have been done. However, the relief is short-lived. I find that every few days I need to take Gelusil which is the only thing that brings relief. Is it safe to take Gelusil so often? Should I have any other tests done, whom should I go to?
