Hi Confuzed.. I haven't tried, nor do I know someone who has tried it, but I discussed it with my surgeon before undergoing my WLS and he said that most people lose a max of 20 pounds with this type of procedure and since am only 5 feet 1 and I had a lot to lose, putting a big baloon in my stomache would have caused me severe nausea..
Just my 2 cents, hope this information is useful..
P.S. Think twice.. and thrice before attempting WLS, I am sure some people do better on the baloon than what my surgeon had predicted (he just wanted to slice me up
). Good luck to you whatever you choose..
