Bariatric (Weight Loss) Surgery

Overview

Bariatric surgery reduces the size of the stomach and, in some operations, changes the route food takes through the gut. It helps people eat less and feel full sooner. Common operations include sleeve gastrectomy and gastric bypass. Surgery works best alongside long-term changes in diet and activity.

Who it may help

• People with severe obesity who have not lost enough weight with diet, exercise and medicines
• People with obesity and related health problems such as type 2 diabetes, high blood pressure or sleep apnoea

Suitability depends on your BMI, your general health and your readiness for lifelong changes.

Before the surgery

You will have a detailed assessment, including medical tests, nutrition counselling and often psychological support. Many patients follow a special diet before surgery.

During the surgery

Most bariatric operations are performed laparoscopically (keyhole) under general anaesthesia.

After the surgery

Your diet moves gradually from liquids to soft foods and then normal textures over several weeks. Lifelong follow-up, vitamin and mineral supplements and regular activity are important for lasting results.

Risks

Risks include bleeding, infection, leaks from staple lines, blood clots, nutritional deficiencies and, in some cases, weight regain.
