I am 65. I got a lap band at 55 but it recently slipped and caused me to develop a hiatal hernia. So I got it removed, the hernia fixed and a revision to a gastric bypass all in one surgery. Recovery was a bit harder than the lap band but I don't think it was that I'm 10 years older as much was how much more involved a bypass is than a lap band.
