It's often a minimally invasive surgery performed with small incisions, a laparoscope (a tiny camera), and special instruments.
There is no need to cut into the stomach or intestine, and recovery is usually faster than with gastric bypass surgery.
The operation can be reversed by surgically removing the band.
The band can be tightened or loosened in the doctor's office to control weight loss and nutritional needs.
Serious complications are uncommon. But gastric bands can slip out of place, become too loose, or leak. Should this happen, you may need more surgery.
