Hi Chrissy , I am 12 years out. And as for acid being worse after surgery, no it's not. I had RNY and my stomach pouch doesn't make any acid ( don't know about the sleeve) . The lower part of my stomach that is still inside makes the acid ( where all stomach acid is always made) and it goes directly into the intestines. I used to have bad indigestion prior to surgery and on the day of surgery I was about to die waiting for surgery on an empty stomach , the acid so so bad I almost backed out because I wanted to eat something to end the acid. They gave me some horrible medicine to help with it but it still was horrible until I was knocked out. When I woke up the indigestion was gone and replace with nausea from the anesthetic but once that wore off , it was great. As for my teeth, I have always had bad teeth and have a full mouth of crowns . Nothing has changed or gotten worse after surgery.
