Not sure if this is going to work for all IBS sufferers but i've been taking 2 tablets a day of Holland and Barrett 3 Billion Friendly Bacteria for the last month and I seem to be feeling better in myself both when it comes to eating and with the unpleasant area.
I was diagnosed with H - Pylori two years ago after suffering for years with indigestion and taking Lansoprazole - I was advised that if you get bad episodes of upset stomachs you must replace the good bacteria in your gut so I started taking Acidophilus - im not saying its a miracle cure but it certainly helps me, so I hope it helps some of my other IBS sufferers.
