I had a partial colectomy (right) 3 months ago. Am beginning to have an "almost normal" BM in the a.m., but a little later will have a large, very loose (watery) bm, and it appears there is some un-digested food in it. Should I continue eating just regular food, as my dr. advised, or eat a soft diet? Oh, I am 84, 5'5", 118 lbs.
