Bariatric Surgery
Bariatric Surgery Options
Bariatric surgery is a highly effective treatment option for individuals struggling with obesity and obesity-related health conditions such as type 2 diabetes, high blood pressure, sleep apnoea, and joint problems.
When lifestyle changes alone have not achieved sustainable weight loss, bariatric surgery can provide long-term results by altering how the digestive system processes food, helping patients feel full sooner and reduce calorie intake.

Gastric Bypass
Gastric bypass is a well-established weight loss procedure that reduces the size of the stomach and reroutes part of the small intestine. This helps patients feel full sooner while also limiting calorie absorption. It is particularly effective for individuals with obesity-related conditions such as type 2 diabetes and severe reflux
Gastric Sleeve
Gastric sleeve surgery, also known as sleeve gastrectomy, involves removing approximately 75–80% of the stomach, leaving a smaller, sleeve-shaped stomach. This limits the amount of food that can be consumed and reduces hunger hormones, helping patients feel satisfied with smaller portions.
The gastric sleeve is one of the most commonly performed bariatric procedures worldwide due to its effectiveness and relatively straightforward surgical approach. It does not involve rerouting the intestines, and many patients experience significant weight loss and improvement in obesity-related conditions
Mini-Gastric Bypass
The mini-gastric bypass is a variation of traditional gastric bypass surgery designed to achieve substantial weight loss with a slightly simpler surgical technique. The procedure creates a long, narrow stomach pouch and connects it to a loop of the small intestine, reducing both food intake and calorie absorption.
This approach can offer excellent weight loss outcomes and improvement in conditions such as type 2 diabetes, high blood pressure, and high cholesterol. The mini-gastric bypass may involve shorter operating time compared to traditional bypass, while still delivering strong metabolic benefits.
