I am 3 months post LNF and I have been feeling great. No reflux, I have lost 30 pounds and I can eat most anything I want. Then 2 weeks ago, I started having pain under my rib cage and nausea every time I eat. After a trip to the surgeon and several gall bladder tests, he has determined that my gall bladder is not functioning properly. Has anyone else had gall bladder problems after a Nissen?
