Roux-en-Y Gastric Bypass
A Roux-en-Y gastric bypass is a well-established bariatric procedure that combines stomach restriction with changes to the digestive system to support significant, long-term weight loss. It is particularly effective for many obesity-related health conditions and may also improve symptoms of gastro-oesophageal reflux disease (GORD). Gastric bypass surgery is offered at Intus Dunedin as part of a comprehensive weight management programme.
This procedure may be suitable for people who:
Have obesity and associated medical conditions
Experience severe reflux alongside obesity
Have Type 2 diabetes
Have not achieved lasting results through other weight management approaches
Require an alternative to sleeve gastrectomy
The most appropriate procedure will depend on your individual health, lifestyle, and treatment goals.
What's Involved in a Roux-en-Y Gastric Bypass?
The procedure is performed using minimally invasive (keyhole) surgery under a general anaesthetic. During the procedure, the surgeon creates a small stomach pouch and connects it directly to a section of the small intestine, allowing food to bypass part of the stomach and upper intestine.
This reduces the amount of food that can be eaten at one time and changes the way calories are absorbed. The procedure also influences hormones involved in appetite, fullness, and blood sugar regulation.
