The Great Debate: Why WHO Withheld Weight-Loss GLP-1 Drugs from its Essential Medicines List

The World Health Organization (WHO) recently made a pivotal decision regarding the highly popular GLP-1 receptor agonists, such as Ozempic and Wegovy, which have revolutionized both diabetes management and weight loss. Despite growing calls for their inclusion, the WHO opted not to add these powerful weight-loss medications to its Essential Medicines List (EML) for obesity treatment.

This decision has ignited a global conversation about access, equity, and the very definition of 'essential' in healthcare.

For years, GLP-1 drugs have been lauded for their efficacy in managing Type 2 diabetes and, more recently, for their significant impact on weight reduction. Advocates, including a group of doctors, scientists, and public health experts, had formally petitioned the WHO to include semaglutide (the active ingredient in Ozempic and Wegovy) for weight loss on the EML.

Their argument was compelling: obesity is a chronic, progressive disease with severe health consequences, and these drugs offer a medically proven pathway to improved health outcomes, particularly for those in low- and middle-income countries who currently lack access.

However, the WHO's expert committee, which evaluates hundreds of medicines every two years, ultimately concluded that despite their undeniable effectiveness, the high cost and the logistical challenges of widespread, long-term administration rendered them unsuitable for the EML's primary goal: ensuring equitable global access to affordable, life-saving, or health-improving medications.

The committee noted that while the drugs are effective, their current pricing could devastate health budgets, especially in poorer nations where many fundamental medicines are still out of reach. Furthermore, the EML traditionally prioritizes medicines for infectious diseases, acute conditions, and treatments that offer significant public health benefits at a manageable cost.

The debate surrounding GLP-1s and the EML highlights a fundamental tension in global health policy.

On one hand, there's a recognition that obesity is a major public health crisis, contributing to a cascade of non-communicable diseases like heart disease, stroke, and certain cancers. On the other hand, the EML operates under strict criteria that balance clinical effectiveness with affordability, feasibility of implementation, and public health relevance.

The committee expressed concerns that adding these expensive, long-term treatments could divert crucial resources from other essential health programs, potentially exacerbating existing health disparities.

While GLP-1s like semaglutide are already listed on the EML for Type 2 diabetes, their non-inclusion for weight loss signifies the WHO's cautious approach to a new class of treatments.

It underscores the ongoing struggle to define which conditions merit 'essential' medical intervention on a global scale, particularly when effective treatments come with a prohibitively high price tag. This decision is not a rejection of the drugs' efficacy but rather a pragmatic assessment of global health economics and equitable access.

It calls for drug manufacturers to engage in pricing strategies that would make these potentially life-changing medications genuinely accessible to all, not just those in affluent nations.
