Hi! Good evening. I am Dr Shareef answering your query. If I were your doctor, I would advise you not to eat from outside like fried, oily, or fast food, as intestinal infections could creep in through these and also in some the intestinal mucosa is sensitive to some of the components of these food resulting in such symptoms of yours. I would advise you to get your stool tested for ova and cyst, and get it treated if positive. Apart from this, you should go for more of roughage and enough liquids in your diet. Also a regular exercise might help you to a great extent. Till then, you could go for a proton pump inhibitor drug along with a probiotic. 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. I wish you an early recovery. Dr Shareef.
