Gastric band surgery is a common weight loss surgery option. It offers the opportunity to lose significant weight loss whilst being the least invasive surgical procedure for weight loss with the risk of fewer complications.
Gastric band surgery is a form of restrictive surgery as it restricts your food intake due to creating a smaller stomach and slowing food movement through your stomach. As you take in less calories you lose weight.
What does a gastric band procedure involve?
A gastric band is a silicone ring that’s placed around the upper part of your stomach and then inflated using saline fluid. This is performed by keyhole surgery. The band creates a small upper pouch that limits the amount of food that you can consume.
The gastric band has a small port attached that allows it to be adjusted by inserting or removing saline fluid. Band fills are carried out on an outpatient basis and are used to control food intake and its passage through your stomach. The aim is to retain a feeling of fullness for as long as possible to suppress your appetite.
How does a gastric band work?
A gastric band makes a small upper pouch that reduces your stomach capacity whilst also creating a slow passage of food from this upper stomach pouch. You will feel full when you’ve only eaten a small amount of food.
Why choose a gastric band procedure?
- Least invasive weight loss surgery.
- Uses general anaesthetic to prevent feeling any pain.
- Home the day after surgery and quick recovery of one to two weeks.
- Adjustable so the rate of food passage from your upper to your lower pouch can be controlled.
- Patients can achieve significant weight loss.
How much weight can I lose with a gastric band?
The weight loss achieved with a gastric band can be significant. On average people lose 40 to 50 percent of their excess weight over 12 to 24 months.
