I had my sleeve surgery 11-16-15 and have had severe heartburn starting 3 weeks post op. I also had heartburn pre-op, but meds seemed to help. Part of the problem is I have no desire to eat which allows for acids to build up. Dr. put me on Zantac which does help. The other issue is when I do eat, I am struggling to chew, chew, chew.... Take your time and follow dr. orders. Don't be afraid to ask dr. for help if heartburn does occur. Good luck- You can do this!
