WGO Practice Guideline - Obesity

Title: Obesity - October 2011


  • Obesity has become more prevalent throughout the world in all age groups.
  • Obesity is a flag for (and often a precondition for) various important chronic diseases.
  • Avoiding obesity may help a person to avoid various chronic diseases; preventing obesity is a better option than trying to control it. As a society, we need to focus on how to prevent obesity in children and adults.
  • Obesity needs to be treated in order to prevent comorbid conditions from developing and to manage them better if present.
  • The social and psychological aspects of obesity cannot be ignored, especially in connection with preventing childhood obesity. These are important issues for most obese adults as well (with a need to prevent discrimination, stigmatization, ridicule, and loss of willpower).
  • Research relating to epidemiology, physiological mechanisms for controlling body weight, the pathophysiology of obesity, and treatment can lead to advances in the management of obesity throughout the world.
