HI ! Good morning. I am Dr Shareef answering your query. Amebiasis is a food born parasitic infestation, and so you should stay away from food from outside which is not infrequently cooked in unhealthy conditions. Go for high roughage diet, and plenty of liquids. If you already had a course of metronidazole in its proper dosage by your treating doctor, I would like to add a proton pump inhibitor, and a probiotic for six weeks. In case of no relief with these, I would not hesitate to refer you to a gastro enterologist for a possible endoscopic evaluation of your intestinal tract for a proper diagnosis, and appropriate management. 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.
