I had my gallbladder removed about a year ago and I have some of the symptoms of dumping syndrome, but I also had them before the surgery so I’m not sure what the cause is. Please try not to be ashamed about this or to ask questions of your doctor. If you don’t talk about it, you cant’t get help and feel better! And believe me, doctors have heard it all — what you descirbe won’t be surprising or strange to them at all. Good luck.
