Gastric Band
A gastric band is an adjustable silicone band placed around the top of the stomach to create a small pouch and reduce how much you can eat.
Quick answer
Gastric Band: what it is, why it's done and what happens
A gastric band is a soft band fitted around the upper stomach, forming a small pouch above it. The band can be tightened or loosened by adding or removing fluid through a small port under the skin.
- Why it is done: It is used as a weight loss procedure for severe obesity, particularly for people who prefer an adjustable, reversible option, though it is now used less often than other bariatric operations.
- What happens: Under general anaesthetic, usually by keyhole surgery, the surgeon places the band around the top of the stomach and connects it to a port beneath the skin.
What it is
A gastric band is a soft band fitted around the upper stomach, forming a small pouch above it. The band can be tightened or loosened by adding or removing fluid through a small port under the skin.
Why it is done
It is used as a weight loss procedure for severe obesity, particularly for people who prefer an adjustable, reversible option, though it is now used less often than other bariatric operations.
What happens
Under general anaesthetic, usually by keyhole surgery, the surgeon places the band around the top of the stomach and connects it to a port beneath the skin. It is often a day case or short stay.
Recovery
Diet progresses from liquids to solids over weeks. The band is adjusted at follow-up visits to control how tight it is. Weight loss is usually more gradual than with bypass or sleeve surgery.
Good to know
Risks and things to consider
Risks include the band slipping, eroding, or the port causing problems, sometimes needing further surgery. Weight loss can be slower and less than with other procedures, and depends heavily on eating habits.
