Does anyone have bile acid/salt malabsorption? I have this and it's pretty bad at the moment. I also have coeliac disease, b12 deficiency, Graves' disease but no thyroid plus a few others. My life is ruled by the loo, food and meds. How do you all cope. I'm just about to start colesevalam as I can't take normal questran. Any heads up on side effects would be good.
