Minimally invasive weight-loss procedure
Personalised care for lasting results
This procedure divides the stomach to create a smaller pouch and connects it so that the first segment of the small intestine is bypassed. The goal is twofold: reduce food volume and reduce calorie absorption.
Performed laparoscopically under general anaesthesia, the mini gastric bypass uses a single connection between the pouch and small intestine. This streamlined approach supports weight loss while preserving normal digestion further along the bowel.
By forming a narrow pouch and bypassing the upper small intestine, mini gastric bypass reduces portion sizes and lowers absorption. Together, these mechanisms help with weight loss beyond simple calorie restriction.
In addition, the procedure influences hunger-regulating hormones, helping to decrease appetite and support long-term weight management. This makes it an effective option for individuals who have struggled with traditional diet and exercise approaches.
Patients often find that these combined effects not only lead to significant weight loss, but also help improve related conditions such as type 2 diabetes, high blood pressure, and sleep apnoea, further supporting overall health and wellbeing.
Like other bariatric procedures, single-anastomosis gastric bypass is considered when obesity is harming health, eating patterns are difficult to control, and significant weight loss hasn’t been achieved with diet and exercise alone. Lifelong nutrition and lifestyle changes are essential for success.
It is generally recommended for individuals who meet specific medical criteria and who understand the commitment required after surgery. Common considerations include:
Mini gastric bypass is a powerful tool that helps restrict intake and control hunger; however, it doesn’t decide what you eat. Long-term success relies on permanent dietary behaviours and regular follow-up.
Ongoing commitment to balanced nutrition, physical activity, and routine medical reviews is essential to maintain the benefits of surgery. Patients are encouraged to view the procedure not as a quick fix, but as the beginning of a structured, sustainable approach to better health and weight management.
