Hi ! Good morning. I am Dr Shareef answering your query. These symptoms could be due to sensitivity of the stomach and intestinal cells to any particular component of the diet, examples being gluten enteropathy and lactose intolerance. The symptoms will vanish once these sensitive components are excluded from the food. This can be diagnosed by way of exclusion of different components from one s diet. I would suggest you to consult a dietecian to know what kind of food one should avoid in such cases and manage the condition accordingly. This is a probable diagnosis once all other investigations are normal. Till then you can continue with the pre biotic prescribed by your doctor. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef
