Hi! Good evening. I am Dr Shareef answering your query. If you eat from outside, please try to avoid it as intestinal infections could creep into your stomach which might have caused such symptoms of loose stools with fever. If I were your doctor, I would advise you for a routine stool test for ova and cyst, and culture sensitivity test and treat it if positive with proper antibiotics. Loperamide might stop diarrhea, but it might not be able to eradicate the persisting infection in your intestines. 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.
