I was banded 3 years ago and have since had it removed and sleeved due to many complications with the adjustments. I did not lose ANY weight with the band. In fact I gained 10kg as my body went into starvation mode. I was so unhappy.
When I discussed the option of the sleeve with my surgeon, he admitted to me that he jumped on the lap band band wagon and if I actually walked in now (pre any WLS) that he would suggest the sleeve. I was appreciative of his honesty.
From personal experience I cannot bang on about the sleeve enough. I can actually eat and feel satisfied.
If your surgeon is open to other surgeries then maybe you need to question why and educate yourself before meeting with them?!?!
