Can I have gastric sleeve surgery after having a hiatal hernia repair?

Yes, you can have gastric sleeve surgery after a hiatal hernia repair. In fact, many patients undergo both procedures simultaneously if they have acid reflux or other related issues. Your surgeon will assess your medical history, the type of repair you had, and any existing symptoms to determine the best approach. In some cases, additional reinforcement of the hernia repair may be needed during the sleeve procedure to reduce the risk of complications.

Yes, you can.  Hiatal hernia repairs are some times done at the same time you are having your bariatric procedure.  Some patients develop hiatal hernia years after a bariatric procedure.  It is absolutely okay to go back and repair a hiatal hernia after having had a bariatric procedure.  

Yes, it can be done, I would definitely consider your case for an evaluation.
The first thing is that you must evaluate yourself with a certified bariatric surgeon to review your case and then proceed to take the best decision for you. Do not get discouraged in the search of options to improve your health.My Best Wishes
