Medication vs. surgery
GLP-1 medications vs. bariatric surgery
The honest summary: bariatric surgery produces more weight loss and holds it longer, while GLP-1 medications avoid an operation and work well for many people as long as they are taken. This is not a contest with one winner. It is a match between two proven tools and your body, your health and your goals. Most clinics sell only one of them. Dr. Eduardo offers both, so the recommendation you get is the one that fits you.

Two proven paths, side by side. The figures are averages from published trials and real-world data; your results depend on your plan, adherence and biology.
| Attribute | GLP-1 medication | Bariatric surgery |
|---|---|---|
| Avg. total weight loss | ~15% semaglutide, ~21% tirzepatide (trials) | ~25% to 35% total body weight, by procedure |
| Durability | Works only while taken; regain common if stopped | Lasting change to gut anatomy and hormones |
| How it works | Weekly injection lowers appetite hormones | One-time procedure reshapes the stomach and hormone signals |
| Best fit | Lower BMI, not ready for surgery, medication-responsive | Higher BMI, wants durable result, or type 2 diabetes |
| Commitment | Ongoing, likely indefinite medication | One procedure plus lifelong follow-up and habits |
| Reversibility | Stop anytime | Sleeve permanent; some procedures revisable |
| They can combine | GLP-1 can treat regain after surgery | Surgery can follow a medication trial |
Sources: STEP 1 (Wilding et al., NEJM 2021, semaglutide ~15% over 68 weeks); SURMOUNT-1 (Jastreboff et al., NEJM 2022, tirzepatide ~21% over 72 weeks); long-term bariatric outcome studies including SM-BOSS (JAMA 2018) and STAMPEDE. Population averages, not individual guarantees. Individual results vary.
Plan your path
What could you lose?
Enter your numbers and compare projected weight loss across every path. Each medication shows a band: the clinical-trial average at the top, down to what people realistically see when they stay on treatment. Surgery figures are durable, real-world outcomes. Nothing you enter is stored or sent anywhere.
Projected weight over time
Percent-of-body-weight curves from published outcomes, applied to your weight. Shaded band is the trial average (top) down to real-world with continued use (bottom).
The band shows what you can expect if you stay on treatment. Most people don't. About 2 in 3 stop GLP-1 within the first year, and stopping brings much of the weight back. That is why the medicine is a long-term commitment, and why a durable procedure is worth weighing.
Medication curves: trial average from STEP 1 (semaglutide, NEJM 2021) and SURMOUNT-1 (tirzepatide, NEJM 2022); real-world continued-use figures from Samuels et al. (Diabetes Obesity & Metabolism 2025) and Gasoyan (Obesity 2025); about 64.8% discontinue within 12 months (Rodriguez, JAMA Network Open 2025). Retatrutide (TRIUMPH) is investigational and not yet FDA-approved. Surgery curves reflect total body-weight loss consistent with SM-BOSS (Peterli, JAMA 2018), STAMPEDE, and the SADI-S systematic review (Spinos, Obes Surg 2021); the monthly trajectory is smoothed for illustration. These are population averages. Your results depend on adherence, dose, biology, and starting point. Educational only, not medical advice.

Which path tends to fit whom
These are starting points, not rules. Many patients move between paths over time, and the two can work together.
Medication often fits when
- ◆Your BMI is in the lower treatment range.
- ◆You are not ready for, or do not want, an operation.
- ◆You respond well to the medication and tolerate it.
- ◆You are comfortable with ongoing treatment.
Surgery often fits when
- ◆Your BMI is higher, or medication has not been enough.
- ◆You want the most durable weight loss available.
- ◆You have type 2 diabetes that could improve or remit.
- ◆You prefer a one-time procedure over indefinite medication.
The Omnia difference
One surgeon who offers both, and a safety net if you ever need it
A medication-only clinic cannot operate if you need surgery. A surgery-only practice has no medical program if you are not ready. Dr. Eduardo, board-certified and fellowship-trained, runs both under one roof. If you start on a GLP-1 and later need an operation, you are already known to your surgeon. If you have surgery and later need medication for regain, the tool is already in the same hands. That continuity is the safety net most weight-loss options do not have.
- ◆Medical and surgical weight loss in one practice.
- ◆An honest recommendation, not a sales funnel.
- ◆The freedom to change paths as your needs change.

On average, bariatric surgery produces more weight loss and holds it longer. Bariatric surgery delivers roughly 25% to 35% total body weight loss depending on the procedure, and that result tends to hold for a decade or more without depending on an uninterrupted prescription. But 'better on average' is not the same as 'better for you.' Medications avoid an operation and suit many people well. The right answer depends on your BMI, health, goals and readiness, which is exactly what an evaluation is for. Sources: STEP 1 (NEJM 2021); SURMOUNT-1 (NEJM 2022); SM-BOSS (JAMA 2018) and STAMPEDE for durable surgical outcomes.
GLP-1 medications work while you take them by lowering appetite hormones. When they are stopped, appetite generally returns and studies consistently show most patients regain a large share of the weight they lost. That is not a personal failure, it is the biology of the medication. It is why GLP-1 therapy is framed as an ongoing treatment for a chronic condition, and why some patients prefer the lasting physiologic change of surgery. Source: post-discontinuation regain data, GLP-1 trials and 2024-2026 meta-analyses.
Often, yes. For many patients, especially at a lower BMI or those not ready for an operation, a physician-supervised GLP-1 program is a reasonable first step. Because Dr. Eduardo offers both medical and surgical weight loss, you are not funneled toward whichever one a clinic happens to sell. You get an honest recommendation, and you can move between paths over time as your needs change.
Yes, and this is one of the strongest reasons to be under a surgeon's care. If weight loss stalls or some weight returns after surgery, adding a GLP-1 medication can help. Recent data show tirzepatide and semaglutide produce meaningful additional weight loss in patients who regained after a bariatric procedure. Having both tools under one physician means your plan can adapt instead of starting over.
It depends on coverage, but the shape of the cost differs. Surgery is a larger up-front cost that is frequently covered at qualifying BMI levels and is generally a one-time expense. GLP-1 medications are a recurring cost for as long as you take them, which for a chronic condition may be indefinitely. Our team verifies your specific benefits and explains real numbers for both paths before you decide.
You decide it with a physician who can offer both and has no incentive to steer you. Dr. Eduardo weighs your BMI and weight-related health, how much durable weight loss you need, whether you have type 2 diabetes, your readiness for a procedure, and your preferences. Some patients start with medication and later choose surgery; some do the reverse; some combine them. The plan is built around you.
