I've heard that VSG can cause heartburn and GERD. I used to have severe GERD, painful esophogeal spasms, and an esophogeal stricture before I had a Nissen Fundoplication (hiatal hernia repair). I'm afraid those problems will return after surgery. The Nissen Fundoplication has to be undone and the surgeon will repair the hiatal hernia in another way. My surgeon assures me that if he repairs the hiatal hernia, I'll be unlikely to have acid reflux. Does anyone have experience with having a hiatal hernia repaired while undergoing a sleeve gastrectomy? Has it worked for you? Have you experienced much acid reflux and heartburn?
