Understanding Bariatric / Gastric Surgery
Bariatric surgery, also known as gastric surgery, includes a range of weight-loss procedures designed to help individuals lose excess weight and reduce obesity-related health risks. These surgeries work by limiting how much you can eat, changing how your body absorbs nutrients, or both.
It’s a specialised health service recommended for individuals who meet specific medical criteria and have not achieved significant weight loss through lifestyle changes alone.
What is Bariatric / Gastric Surgery?
Common types of bariatric surgery include:
Gastric bypass: Creates a small pouch in the stomach and reroutes the intestines
Sleeve gastrectomy: Removes a large portion of the stomach to reduce capacity
Adjustable gastric band: Places a band around the upper stomach to restrict food intake
Biliopancreatic diversion: A more complex surgery that reduces food absorption
Each procedure varies in approach and effect but aims to support significant and sustained weight loss.
