WHO Guidelines on GLP-1 Drugs for Weight Loss

WHO Guidelines on GLP-1 Drugs for Weight Loss
  • Context: 

  • The World Health Organization (WHO) has issued its first global guidelines supporting the use of Glucagon-like peptide-1 (GLP-1) therapies for the treatment of obesity in adults 

  • What are GLP-1 Drugs? 

  • They are originally used for Type 2 diabetes. 

  • These drugs have revolutionized obesity treatment by effecting significant weight loss and offering metabolic benefits.  

  • Currently, there are 12 approved GLP-1 therapies 

  • Key Guidelines: 

  • The WHO recommends GLP-1 drugs for long-term treatment in adults (excluding pregnant women).  

  • However, the recommendation is conditional due to high costs and limited data on long-term safety and efficacy after discontinuation. 

  • The guidelines emphasize that medication alone is insufficient. 

  • Intensive behavioural interventions (diet and physical activity) must continue alongside the drugs. 

  • The guidelines explicitly recognize obesity as a chronic disease requiring lifetime care shifting away from viewing it merely as a lifestyle issue. 

  • Challenges: 

  • Equitable Access:  

  • High costs and limited supply are major barriers.  

  • Current production capacity can cover only ~100 million people (less than 10% of need). 

  • Global Impact:  

  • With the global cost of obesity predicted to reach $3 trillion annually by 2030, the WHO suggests manufacturing generics and including these drugs in the essential medicines list to ensure wider access.
