Had my gallbladder removed?

My gallbladder was removed in 2008 but they never said I have to avoid fatty foods completely. Though then again, gallstones can return to bile ducts anyway, so thinking with a common sense, one has to be careful even after gallbladder removal and not eat too much fatty foods, only occasional treats every now and then. The fat from the food does cause slight diarrhoea because it does not absorb as well as with the gallbladder in place, and of course it is not very good idea to be visiting the toilet all the time.
