I have had diarrhea for about a week. I normally have very loose movements because I had colon cancer and several inches of my colon was removed. I am starting to have pains in my lower stomach and can t keep anything I eat in, seems to go straight through. The liquid is not black and I have not seen any blood. Can I take an anti-diarrheal? I started with the 81mg asparin about a month ago but stopped it thinking that may be what is upsetting my system.
