Hi! Good evening. I am Dr Shareef answering your query. If I were your doctor I would advise you to avoid eating from outside to prevent any chances of intestinal infections creeping in. A stool test for ova and cyst would diagnose it , and treatment would solve your problem. Apart from this, I would also advise you with a pro biotic drug and a proton pump inhibitor for a possible symptomatic relief. Also, any food allergy would have to be ruled out by serial addition/exclusion of any such food which you feel would possibly aggravate your symptoms. 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.
