I have been losing weight steadily after going through my gallbladder surgery. I have not changed my diet plan or level of activity. Before the surgery I was overweight but now I am normal as far as weight is concerned. I guess this has something to do with my metabolism. I guess there must be some effect of that surgery on my metabolism. What do you guys think about it? Can someone tell me what exactly happens with metabolism after gallbladder surgery? I would really appreciate it. Thanks.
