I was having ibs for whole of april. Doctor prescribed ornida 500, drotin ds, and unienzyme tablet. (all twice a day) for 4 days. During this course and since the day my ibs started, I ate too less food due to the fear of pain in stomach which bothered alot. Mostly had curd, rice, upma & liquid diet. Facing flutters in chest, like heart pausing for a second. These flutters occur many a times a day. Gets relieved when I take b12 medicine. It's been a week I am facing these flutters along with fast heart rate. No avail yet. Pls advise.
