Hi ! Good morning. I am Dr Shareef answering your query. If I were your doctor, I would modify her diet more to high roughage and enough of liquids. Apart from this I would also add a course of metronidazole for her along with a probiotic and a proton pump inhibitor drug. If the problem continues, I would refer her to a gastro enterologist for a possible endoscopic evaluation of her intestinal tract for a proper diagnosis and further 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.
