Please describe the down side to lap band surgery?

Lap band surgery: Your chance of losing the weight you want is less then if you had a sleeve or a bypass. The band is a foreign object and although it does not cause harm but if it doesn't work for you and you want more surgery , it becomes more difficult due to scar tissue and there is an increased chance of complications such as leaks.

Lap band: Slower weight loss, lower total weight loss, high failure rate, 20-30% lifetime re operation rate, it can cause reflux (the gastric bypass cures this), it can cause esophageal dysmotility, the band can slip/prolapse, the band can erode or cut into the stomach, the band can leak, the port can flip. It is however, the safest weight loss operation, and it is reversible.
