Bariatric Surgery

Why consider it?

It is generally acknowledged today that once an individual’s weight exceeds a certain range, they are more likely to suffer from a wider variety of obesity-related diseases, and may also experience physical restrictions. Consequently, their quality-of-life decreases, and their chances of dying at a premature age increases. Additionally, some individuals who live with obesity, may also suffer from mental health conditions such as depression, characterised by feelings of sadness, hopelessness, and loss of interest in activities once enjoyed.


Many individuals have spent years yo-yo dieting and exercising, achieving some weight loss at times, but frequently experience regain of the weight lost. It is important to understand two things:

  1. that dieting often leads to long-term weight gain, not weight loss, and
  2. that dieting often cannot address long-term health concerns caused by obesity

Bariatric (weight-loss) surgery is a powerful tool that can very effectively reduce weight and the severity of diseases, potentially eliminating them and improving long-term health outcomes.

Bariatric Surgery works in a number of different ways. In most procedures, the size of the stomach is commonly reduced. In some procedures, the bowel may be bypassed to reduce the amount of nutrients, or calories, absorbed. The goal of bariatric surgery is to not only reduce the amount of food that is eaten or absorbed, but also to alter the hunger and fullness signals to the brain.
