Will You Lose Massive Amounts Of Weight After The Lap Nissen Fundoplication ?
The Nissen/Fundoplication is not considered a treatment for obesity. While some of the stomach is used to wrap the esophagus it does not cause a significant difference in stomach size. I did find a research article that investigated weight loss after LNF surgery. On average a year after the LNF procedure people lost 8.9 lbs. People who weighed more before the procedure tended to lose more than those who didn't.
So, while it is possible to lose weight after the LNF procedure, one shouldn't expect "massive" amounts based on the surgery alone.
