I was told by a consultant that I had IBS approx 20 yrs ago.My consultant that I have for past 8 yrs.thinks that my problems may be caused ny Bile malabsorption.He did not do any tests,not great at organising tests except endoscopies and colonoscopies but I am pleased that he has come up with this diagnosis.I feel that he is correct as some of the discomfort that I feel is similar to the pain that I had before I had my Gallbladder removed.I have read that the Bile can be drained but do not know if this is a severe procedure.
