From last few days after eating any thing I feel gas, back ache and sudden urge to stool. Sometimes the stool are like loose motion and with little bit of foam(may be mucus) . My first stool in the morning are clear but after that I feel like gas and little pain in stomach, but after eating break fast I feel relax. I have taken PENTADEC DSR for 10days, but it gives temporary relief. I have stopped drinking milk as after that my stomach get bloated. After searching the internet I feel my symptoms are of IBS. please suggest proper diet and medicine for the same.
