At a glance
| ESG | GLP-1 medications | |
|---|---|---|
| Type | Endoscopic procedure (one-time) | Prescription medication (ongoing) |
| Mechanism | Reduces functional stomach volume via internal sutures | Regulates appetite and blood sugar via GLP-1 receptors |
| Typical weight loss | ~15-20% TBW at 12-24 months (varies) | ~10-20% TBW with ongoing use (varies by agent and patient) |
| Duration of effect | Durable structural change; long-term data evolving | Effective while taking the medication |
| Discontinuation | Sutures remain in place | Weight regain is common after stopping in published trials |
| Common side effects | Nausea, abdominal pain, reflux in some patients | GI side effects, fatigue, injection-site reactions |
| Time commitment | Single procedure + structured follow-up | Weekly or daily dosing indefinitely |
| Cost profile | Defined upfront cost | Recurring prescription cost |
Why some patients explore ESG while on a GLP-1
- Concerns about long-term medication use, side effects, or cost.
- Weight-loss plateau despite consistent adherence.
- Desire for a structural, one-time intervention rather than ongoing therapy.
- Preparation for eventually transitioning off medication under physician supervision.
None of these are reasons to stop your medication on your own. A clinical evaluation is required.
When GLP-1 medications may be the better fit
- Strong metabolic indication (e.g., type 2 diabetes) where the medication treats multiple conditions.
- Patient preference for a non-procedural approach.
- Recent surgery or active medical contraindications to endoscopy.
Combination approaches
Some patients use GLP-1 medications and ESG together at different points in their journey — for example, using medication to prepare for or maintain results after the procedure, always under physician supervision.
FAQ
Can I have ESG if I am currently taking a GLP-1 medication?
Many patients on GLP-1 medications explore ESG as an alternative or complement. Medication changes should only be made in consultation with your prescribing healthcare professional.
Does ESG replace GLP-1 medications?
ESG is a procedural intervention with a different mechanism than GLP-1 medications. Treatment decisions are individualized and made with a qualified physician.
What happens if I plateau on a GLP-1 medication?
Plateaus are common with any weight-loss approach. A clinical evaluation can help review nutrition, activity, dose, and whether additional options — including ESG — may be appropriate.
