Gastric bypass surgery is one of the most widely performed and trusted procedures for weight loss across the world. It helps people struggling with obesity take back control of their health by reducing both appetite and food absorption, leading to consistent, long-term results.
What Is a Gastric Bypass?
Gastric bypass, often referred to as a Roux-en-Y bypass, is a type of surgery that changes the way the stomach and small intestine handle food. The stomach is stapled to create a small pouch, which is then connected directly to a lower part of the small intestine. This reroutes food, bypassing much of the stomach and the upper part of the intestine.
As a result, patients feel full after eating a much smaller amount of food, and the body absorbs fewer calories from what is consumed. The surgery is usually carried out laparoscopically under general anaesthetic.
Who Is It For?
This procedure is particularly effective for individuals with a higher BMI, or those with type 2 diabetes and other obesity-related conditions. It may also be suitable for people who have not had success with other types of surgery or who experience severe acid reflux that makes other options unsuitable.
An experienced bariatric surgeon will help assess if gastric bypass is the right fit based on individual health needs and long-term goals.
