Weight Loss Surgery Overview

Body weight is measured by Body Mass Index – Measure Your BMI

Obesity surgery may be suitable for adults who have

  • BMI of 40 or greater (massive obesity)
  • BMI of 30 to 35 or greater when it is combined with a significant health condition that could be improved through surgery (diabetes, high blood pressure, sleep apnoea syndrome, joint disorders, etc.)

Such patients should have attempted, without success, to lose weight by non-surgical means (including nutritional and physical activity) over several months, and present no potential complications to surgery (e.g. alcohol addiction) or to general anaesthesia.

Obesity cripples the body, but as you lose weight, the burden on your heart, bones and joints is reduced.
