Weight loss surgery procedures help Australians achieve sustainable weight loss when diet and exercise alone haven't worked. Compare gastric sleeve, gastric bypass, and other bariatric surgery options to find the right procedure for your health goals.
Gastric sleeve surgery is the most commonly performed weight loss surgery in Australia. The procedure removes approximately 80% of the stomach, creating a sleeve-shaped stomach about the size of a banana.
Gastric bypass (Roux-en-Y) creates a small stomach pouch and reroutes the small intestine. This restricts food intake and reduces calorie absorption, making it highly effective for weight loss and diabetes management.
