Outcomes of Bariatric Surgery :: Who is Eligible for Surgery?

• Most forms of bariatric surgery have been associated with an average weight loss of at least 50% of excess, sustained indefinately. For example, a patient weighs 130kg with an "ideal" weight of 70kg according to a BMI of 25. Her excess weight is 60kg. If she lost 50% of her excess weight, she would stabilise at about 100kg
   
• Many people succeed in losing more than 50% excess weight loss, and some lose significantly less than 50%. This depends on many factors, including your original weight, the operation you have, and the commitment you have to lifestyle change after the operation
   
• With successful bariatric surgery, diabetes will almost always improve, sometimes to the point where no further medication is required. Complete remission of diabetes can occur in 50-75% of cases
   
• Sleep apnoea responds very well to bariatric surgery in around 90% of cases and it is common for a patient to no longer need CPAP treatment down the track
   
• Other benefits which are common include: improvements in blood pressure, increased fertility in women of child-bearing age, decreased joint pains, increased energy levels and improved self esteem
   
• It is likely, although not unequivocally proven, that successful bariatric surgery will increase life span, depending on the individual's paticular circumstances. It may also reduce the incidence of certain obesity-related cancers

The decision to go ahead with weight loss surgery is a significant one. This decision should be accompanied by a resolution to change one's lifestyle permanently to include healthy dietary habits and a regular exercise programme. We encourage any patient considering surgery to seek discussion with an experienced bariatric specialist to decide on whether surgery is an appropriate intervention and which operation is most suitable.
