2 years after gallbladder removal if I don't eat after long periods of time I get really bloated. I can't eat while at work so what can I do?

Try cholestyramine. These symptoms may be due to bile making it to the colon where it can be irritating causing bloating and diarrhea. Usually eating would bind up the bile. But if you can't eat there is a medicine called Cholestyramine you can take to bind up the bile. Ask your doctor about it.
May be unrelated. It seems likely that your bloating feelings without eating wouid not be related to your gallbladder surgery. See your family doctor for an evaluation to see what might be the cause of your feelings.
