I suffered with IBS for 10 years and lost a lot of weight/muscle tone as a result. On changing GP after house move, I discovered my GP had also been a sufferer. He recommended I try Selenium with Zinc. You can get these at Holland & Barrett. I had nothing to lose and gave it a whirl. Within 3 weeks I had my life back; it was pretty incredible. Obviously, this may not work for everyone, but if you suffer, it is certainly worth a try. I also packed in smoking - a major trigger for me. After taking these supplements for a few years, I am now completely free of IBS. I really hope this helps some of you.
