This directly challenges the Medicare cost-savings thesis by creating NEW healthcare costs (disability, falls, fractures) that may offset cardiovascular and metabolic savings. ### Additional Evidence (extend) -*Source: [[2025-12-01-who-glp1-global-guidelines-obesity]] | Added: 2026-03-16* +*Source: 2025-12-01-who-glp1-global-guidelines-obesity | Added: 2026-03-16* WHO issued conditional recommendations (not full endorsements) for GLP-1s in obesity treatment, explicitly acknowledging 'limited long-term evidence.' The conditional framing signals institutional uncertainty about durability of outcomes and cost-effectiveness at population scale. WHO requires countries to 'consider local cost-effectiveness, budget impact, and ethical implications' before adoption, suggesting the chronic use economics remain unproven for resource-constrained health systems. ### Additional Evidence (challenge) -*Source: [[2025-01-01-jmir-digital-engagement-glp1-weight-loss-outcomes]] | Added: 2026-03-16* +*Source: 2025-01-01-jmir-digital-engagement-glp1-weight-loss-outcomes | Added: 2026-03-16* Danish cohort achieved same weight loss outcomes (16.7% at 64 weeks) using HALF the typical semaglutide dose when paired with digital behavioral support, matching clinical trial results at 50% drug cost. If this half-dose protocol proves generalizable, it could fundamentally alter the inflationary cost trajectory by reducing per-patient drug spending while maintaining efficacy. diff --git a/domains/health/glp-1-persistence-drops-to-15-percent-at-two-years-for-non-diabetic-obesity-patients-undermining-chronic-use-economics.md b/domains/health/glp-1-persistence-drops-to-15-percent-at-two-years-for-non-diabetic-obesity-patients-undermining-chronic-use-economics.md index 861a1c801..02d161e5c 100644 --- a/domains/health/glp-1-persistence-drops-to-15-percent-at-two-years-for-non-diabetic-obesity-patients-undermining-chronic-use-economics.md +++ b/domains/health/glp-1-persistence-drops-to-15-percent-at-two-years-for-non-diabetic-obesity-patients-undermining-chronic-use-economics.md @@ -55,13 +55,13 @@ The $50/month out-of-pocket maximum for Medicare beneficiaries (starting April 2 ### Additional Evidence (extend) -*Source: [[2025-07-01-sarcopenia-glp1-muscle-loss-elderly-risk]] | Added: 2026-03-16* +*Source: 2025-07-01-sarcopenia-glp1-muscle-loss-elderly-risk | Added: 2026-03-16* The discontinuation problem is worse than just lost metabolic benefits - it creates a body composition trap. Patients who discontinue lose 15-40% of weight as lean mass during treatment, then regain weight preferentially as fat without muscle recovery. This means the most common outcome (discontinuation) leaves patients with WORSE body composition than baseline: same or higher fat, less muscle, higher disability risk. Weight cycling on GLP-1s is not neutral - it's actively harmful. ### Additional Evidence (extend) -*Source: [[2025-01-01-jmir-digital-engagement-glp1-weight-loss-outcomes]] | Added: 2026-03-16* +*Source: 2025-01-01-jmir-digital-engagement-glp1-weight-loss-outcomes | Added: 2026-03-16* Digital behavioral support may partially solve the persistence problem: UK study showed 11.53% weight loss with engagement vs 8% without at 5 months, suggesting the adherence paradox has a behavioral solution component. However, high withdrawal rates in non-engaged groups suggest this requires active participation, not passive app access.
