Sometimes GERD cannot be completely treated only with medications. If you have done lifestyle changes, changed your diet and are already on medications, then I think you should consider surgical option. This is laparoscopic surgery so very minimal pain, minimal cuts on your body and faster recovery. It is a physiological surgery. Also since you are very young, its better that you think about surgery as the medicines you will have to take for a longer period of time and there is a chance that in longer run patients may develop Barrett's esophagus which is a serious complication.
