However, I took it because I had a high liquid output and stomach pains and it seemed a sensible thing to do. However, in all probablility I had a problem with the blockage anyway that my consultant thought was probably connected with adhesions. Since then I have steered very clear of using Imodium. I think I've read that taking it has its risks for people with an ileostomy and it is probably not a good idea if you have a high output as it probably means that the small intestine is responding to a blockage by producing lots of fluid to try to shift it and the Imodium acts to damp this down.
However, some people have clearly taken it without problem and we are all clearly different. However, the pain I had with the blockage was the worst I've ever experienced but then I am only a bloke and I am sure lots of women would say that nothing beats childbirth!
