Hi I have shared my situation several times on here and have always had support and advice in the past. I am again hoping there's someone who may relate to my current situation. I believed and was told that I had IBS some years ago but now it seems that any food can cause a flare up which lasts for a week or more. I had campylobacter 7 months ago and took approx 3weeks to clear, but before Christmas after eating in a restaurant I had diarrhea for 2 weeks, which cleared up but February of this year I had a viral infection, persistent cough, shortness of breath and head cold. Again I also had diarrhea. Is there any advice regarding gaining a stronger immune system. I probably should also add that I have Chronic Myeloid Leukaemia which is treated successfully with a chemotherapy pill. I would be appreciative of any advice, thanks to all for reading this lengthy, probably complicated message .
