I've lost 52 pounds since June of last year, down from 214 to 162. Did this by drastically changing my diet. Stopped eating fast food which I was consuming in excess of 5 times per week. Also gave up sweets, sodas, and fried foods, and white bread. Started eating more fruits, vegetables, baked or grilled chicken, and whole grains. Two months after chaning my eating habits I started having stomach issues. Ended up having my gallbladder removed in December after having 3 attacks due to a gallstone. I still have upper abdominal tenderness, burping, and hiccups. I know that something else is still going on. Did I do something diet wise that could've caused these issues? Prior to all this I'd never had any health issues. Why would losing cause all of this?
