How can obesity be treated?

Expert opinion:

There is no single effective treatment for long-term weight loss. Lifestyle changes underly all currently effective treatments and should be emphasised.1

Some of the findings from a major report produced by the National Health and Medical Research Council (NHMRC) are shown.  These findings need to be read together with the full report published by the NHMRC which is easily available online (see reference below).

Surgical options

Expert opinion:

  • Surgery—mainly of the types that restrict the intake or absorption of food—is the most effective weight-loss treatment in severely obese patients2
  •  Surgically induced weight loss results in a marked reduction in some of the co-morbidities (other illnesses) associated with obesity (particularly diabetes) and an improvement in quality of life
  • Although it may appear expensive relative to other treatments obesity surgery is one of the most cost-effective treatments available.2

There are three main types of weight loss (or bariatric) surgery conducted in Australia.  These are:

  1. Gastric bypass
  2. Non-adjustable gastroplasty
  3. Adjustable gastric banding (the LAP-BAND® System)

  • Diet
  • Exercise
  • Diet and exercise in combination
