Ditto to what Kris says. I was banded 4.5 years ago and have about 200 dives since then with no problems. I did clear it with my doctor, initially. Soon I will be in the Canary Islands, then the Galapagos islands. Loosing the weight ( 150 lbs ) has certainly made diving more enjoyable. I no longer have a weight belt that would sink the titanic.
