How does the LAGB work?
The band works in multiple ways:
- Restriction – The inflatable band limits the volume of food that can be consumed at one time by restricting the diameter at the top of the stomach.
- Induces early satiety – The constant gentle pressure at the top of the stomach slows the movement of food into the stomach, in turn giving the feeling of satiety (a sense of fullness) on a smaller amount of food.
The gastric band has a small port attached, that is placed internally in the abdomen. Fluid (saline) can then be inserted or removed to control the restriction of the band. These adjustments (or ‘band-fills’) are performed more frequently in the first year, and then usually on an as-needed basis.
