This depends on the type of surgery you are having. If you are having surgery or the TIF procedure performed for GERD and/or hiatal hernia, you will be on liquids and softer food for the first few weeks after surgery. You will need to avoid bread, meat, and carbonated beverage during the healing phase in the initial weeks after surgery. For gallbladder surgery, I typically recommend sticking to a low-fat diet for the first two weeks, then gradually introducing fats thereafter, if you desire. For colon surgery, a low fiber diet is recommended during the first few weeks of recovery.
