Hi ! Good evening. I am Dr Shareef answering your query. The first advice from me to you is to stop eating from outside completely if you do specially the fried, oily and fast food. This might be causing recurrent intestinal infection because of poor cooking hygiene. Apart from the hygiene, some food components specially in the fast food from outside may induce sensitivity to the intestinal mucosa, leading to all your symptoms which you just described. This sensitivity could be due to anything like a lactose sensitivity, and gluten sensitivity, the incidence of these disorders being under estimated in most of the places. Once intestinal infection is excluded, sensitivity to a particular component of the food can be diagnosed by gradual exclusion of that particular component from your diet. This can be well controlled by a qualified dietician and the moment that particular component is excluded, the person start feeling far better. Thus the treatment varies from one to the other. There has to be a high index of suspicion of these not very uncommon pathology. 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.
