New obesity guideline highlights growing role of GLP-1 medicines in heart health
18 May 2026
The new guidance was developed by the Heart Foundation with support from a 22-member expert taskforce, including three GPs, and was launched at the World Health Assembly in Geneva.
The statement gives practical advice for healthcare professionals on four key areas of obesity care — medications, nutrition, physical activity, and bariatric surgery.
Experts behind the statement said GLP-1 medicines and other incretin-based treatments have changed the way obesity is managed. Research shows these medicines can improve cardiometabolic health and lower the risk of serious cardiovascular events in some patients.
However, the guidance also makes clear that medicines should support lifestyle changes, not replace them.
Heart Foundation Chief Medical Adviser Professor Garry Jennings said obesity and overweight now affect two out of three Australians, increasing the risk of heart disease and other chronic health conditions.
He said healthcare professionals need clear, evidence-based guidance as newer obesity treatments become more widely discussed and used.
The statement comes as discussions continue around possible PBS listing options for semaglutide (Wegovy) for people with obesity and cardiovascular disease.
The Pharmaceutical Benefits Advisory Committee has recommended prioritising high-risk patients, including those with cardiovascular disease, if GLP-1 obesity treatments receive PBS subsidy approval.
Professor Jennings said access and affordability remain important issues, especially for patients who may benefit the most from treatment.
GP Dr Mark Mellor, who helped develop the statement, said obesity and cardiovascular disease are closely connected and should not be treated as separate conditions.
He said the guidance gives GPs clearer pathways on when to move from lifestyle support to medicines or surgery if needed.
The statement also describes obesity as a chronic, long-term condition and highlights the importance of reducing stigma in healthcare.
Experts involved in the guideline said managing obesity works best through a team approach involving GPs, dietitians, exercise professionals, psychologists, and family support where possible.
