Hi.. Welcome to HEALTHCARE MAGIC .. I have gone through your query and can understand your concerns.. As per your complain burping or belching is a process of releasing gas orbair that is either swallowed while eating or what is formed in the stomach and intestines while breakdown of food.. Burping few times after meals us not an abnormal sign but chronic excessive burping can be due to a few common causes aa well as digestive problems and thinking directly of cancer is not a good idea.. It can be due to a number of cases like Indigestion or dyspepsia, constipation, stomach infection,acid reflux, stress, irritable bowel syndrome, Crohn s disease, lactose intolerance etc.. You should consult a Gastroenterologist and get evaluated and he can do certain investigations like Upper G. I Endoscopy, Enteroscopy, blood investigation and treatment can be planned accordingly.. As of now you can take light and small meals every 2 to 3 hours, take antacid before meals, avoid spicy food, drink plenty of water and do moderate workout or walk after meals.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
