I have been having mucus in my stool for approx. 2 months. I have always had some problems with constipation but have never had to take a laxative until twice in the last two months. Twice I have passed clear mucus...once before we went on a cruise to Mexico and once after. My doctor gave me one week of Bactrim to cover E coli. I am still having mucosa stools but they are not clear, light brown and not formed. Once the laxative works, I have no stools. My diet has change only in that I have stopped eating bread, milk, raisin bran and sweets. I am stumped as to what I need to change . My last colonoscopy showed only two polyps that were removed (last year). I would appreciate your help.
