Hi Jody,
I have been on Colestipol prescribed by my oncologist for several years. It is important to keep track of the foods you eat that may exaserbate the issue. A place to start is Fodmap free on the web and journal what works and does not. I also used Metamucil which may help too. I hope this helps.

Thanks for the reply, sorry for the long reply, I have a food diary so keeping track of all my food and treats , doctors seem to have hit a brick wall with it all, on my last admission to hospital beginning of January, I got really stressed out over it all, so now looks like they are going to try other things, this is the Gastro team as my Heamotolgy team just don't seem bothered, this has been going on for over 18 months now have done all the diets like gluten free, dairy free, but seems like there is a time, as seems to happen around every few weeks & can last anything from a few days to a few months so frustrating, not even taking lerperimide works & I've taken a whole box in a day sometimes, I'm from the UK too
