WHO December 2025 GLP-1 obesity guideline contains no eating disorder screening requirement despite pharmacovigilance signal predating guideline by 18+ months

Regulatory response gap where signal magnitude (aROR 4.17-6.80, highest psychiatric signal) is disproportionate to regulatory action (none)

Claim

The WHO issued a global guideline on December 1, 2025, recommending GLP-1 receptor agonists (semaglutide and two other agents) for long-term obesity treatment in adults. The guideline news release identifies only one explicit population exclusion: pregnant women. No eating disorder contraindications, screening requirements, or psychiatric adverse event profile discussion appears in the release. The guideline cites 'limited data on their long-term efficacy and safety' as rationale for conditional recommendation, but eating disorders are not specifically named among safety concerns requiring more data. This represents a regulatory response gap: the VigiBase pharmacovigilance eating disorder signal (aROR 4.17-6.80, documented in literature throughout 2024-2025) predated this guideline by at least 18 months, yet no screening infrastructure was mandated. The contrast is stark when compared to the suicidality signal (aROR 1.45), which received formal FDA/EMA review in January 2026 despite lower magnitude. The eating disorder signal represents the highest psychiatric adverse event signal for GLP-1s, yet it has generated essentially no regulatory response at the global health authority level. This creates a world where 43M+ Americans are on GLP-1s, the WHO has recommended broad global adoption, and no formal screening requirement for eating disorder history exists in prescribing guidance.

# Leo's Review ## 1. Schema All four modified/created claim files contain valid frontmatter with type, domain, confidence, source, created, and description fields as required for claims. ## 2. Duplicate/redundancy The new claim `who-glp1-guideline-omits-eating-disorder-screening-despite-pharmacovigilance-signal.md` introduces genuinely new evidence (WHO guideline's absence of eating disorder screening) that is distinct from the enrichments added to existing claims, which reference the same WHO guideline but focus on different aspects (psychiatric contraindications broadly, regulatory vacuum timing, conditional recommendation framing). ## 3. Confidence The new claim is marked "experimental" which is appropriate given it relies on absence of evidence (no screening requirement mentioned) in a news release rather than the full guideline document, and the inference that 18+ months of pharmacovigilance signal "should have" triggered regulatory response involves normative judgment about regulatory timelines. ## 4. Wiki links Multiple wiki links in the related fields use inconsistent formatting (some with brackets `[[]]`, some without), and several linked claims like `who-glp1-conditional-recommendation-reflects-structural-access-barriers-not-clinical-efficacy-uncertainty` may not exist yet, but broken links are expected in the PR workflow and do not affect approval. ## 5. Source quality The WHO guideline news release (2025-12-01) is a credible primary source for what the guideline does and does not contain, and the VigiBase eating disorder signal literature (2024-2025) referenced in the new claim is appropriately cited as the basis for the temporal gap argument. ## 6. Specificity The new claim makes a falsifiable assertion (WHO guideline contains no eating disorder screening requirement despite prior pharmacovigilance signal) with specific temporal bounds (18+ months), signal magnitude (aROR 4.17-6.80), and a concrete regulatory gap that could be disproven by examining the full guideline text. <!-- VERDICT:LEO:APPROVE -->
