Gastric Bypass Surgery
Gold-standard bariatric surgery for lasting weight loss
Gastric bypass surgery is considered the most effective bariatric procedure — a small gastric pouch is created and connected directly to the small intestine, reducing both food intake and calorie absorption while also improving metabolic conditions like Type 2 diabetes.
The procedure produces significant and durable weight loss by combining restriction (smaller stomach) with malabsorption (bypassing a segment of intestine), and is associated with high rates of diabetes remission, blood pressure improvement and resolution of sleep apnoea.
Key Benefits
- Most effective bariatric procedure for total weight loss

- Improvement in metabolic and cardiovascular risk factors

- Patients who have not achieved lasting results with other methods

Frequently Asked Questions
How much weight can I lose after gastric bypass?
Most patients lose 60–80% of their excess body weight within 12–18 months, with sustained results at 5 years.
