GLP-1 vs Bariatric Surgery

Bariatric surgery produces larger and more durable weight loss but is irreversible and surgical. GLP-1 therapy is reversible, non-surgical, and now closes much of the historical gap, especially with tirzepatide-class molecules.

Choose GLP-1 therapy

GLP-1 therapy is the provider-reviewed first-line for most candidates and avoids surgical risk.

Choose Bariatric surgery

Bariatric surgery is appropriate when BMI thresholds and comorbidity burden warrant surgical intervention and the candidate accepts permanence.

Educational. Final pathway selection is provider-reviewed via synchronous video consultation against your biomarkers, history, and goals.

Frequently asked

Can GLP-1 be used after surgery?

Yes — provider-reviewed adjunctive use is common for incomplete response or regain.

Is surgery still necessary?

For some candidates yes; for many, modern GLP-1 therapy is now sufficient.
