I had my gallbladder removed on Nov. 3, 2012. I had the same kind of symptoms as you do. Everything I would eat would give me diarrhea until i switched my diet. I switched to a gluten free diet. I avoid all wheat products. At first i thought fat was the problem but for some reason avoided wheat changed that. i do not experience gas as frequent, bloating, nausea, and haven’t had any more diarrhea episodes. I really do not think fat is the problem, it is the gluten (wheat products) which is in mostly everything that is eaten by everyone. try the diet and see how it makes you feel. i would like to know.
