Yes, hiatus hernia
surgery will help reduce most of your symptoms.
However there are few complications associated with the surgery, hence discuss with your surgeon about the procedures.
Meanwhile continue to take your antacid
medications, follow prescribed diet, after food walk for a little bit before lying down.
Hope I have answered your query. If you have any further questions I will be happy to help
Wish you good health,
