This challenges the inflationary cost projection if the optimal intervention is time-limited medication + permanent behavioral change rather than lifetime pharmacotherapy. 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 7c1504ba..d573de2d 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 @@ -97,7 +97,7 @@ GLP-1 behavioral adherence failures demonstrate that even breakthrough pharmacol ### Additional Evidence (extend) -*Source: [[2026-03-01-glp1-lifestyle-modification-efficacy-combined-approach]] | Added: 2026-03-19* +*Source: 2026-03-01-glp1-lifestyle-modification-efficacy-combined-approach | Added: 2026-03-19* Weight regain data shows GLP-1 alone (8.7 kg regain) performs no better than placebo (7.6 kg) after discontinuation, while combination with exercise reduces regain to 3.5 kg. This suggests the low persistence rates may be economically rational from a patient perspective if medication alone provides no durable benefit—patients who discontinue without establishing exercise habits return to baseline regardless of medication duration.
