Obesity Medicine · Clinical Pearl
Stopping obesity medication often removes the biologic support that maintained the weight loss
Lede: When weight returns after an effective obesity medication is stopped, that does not necessarily mean the treatment failed—it may mean the treatment effect was withdrawn.
Why it matters
Randomized withdrawal data show substantial weight regain after discontinuation of effective incretin-based therapy. In the STEP 1 extension, participants regained about two-thirds of their prior semaglutide-associated weight loss within one year after treatment withdrawal. In SURMOUNT-4, participants switched from tirzepatide to placebo regained substantial weight, while those who continued treatment maintained and extended their loss. Current obesity guidance increasingly treats pharmacotherapy as potentially long-term treatment for a chronic disease.
The pearl
Judge obesity medication the way you judge antihypertensive therapy: by what happens while the treatment is active, not by whether the disease returns when treatment is removed.
