The band is an inflatable band which is placed around the top of the stomach, creating a small pouch above it. It is connected via a tube to a port which sits under the skin on the tummy. Fluid can be injected or removed via this port to tighten or loosen the band. This is a gradual process with adjustments performed repeatedly over time. The aim is to not have it too tight where food is unable to pass and comes back up, and not too loose where you don’t feel full after eating.

Pros: Technically more straightforward operation, reasonable weight loss and outcomes

Cons: Requires more frequent follow-up for band adjustment, Bands can cause problems such as infection, erosion, leakage
