GLP-1 medications and bariatric surgery are often framed as competitors. In practice they are different tools for different situations, and the fact that Omnia Health offers both means the recommendation can follow you rather than the other way around. Here is how to think about the choice.
What each approach does
GLP-1 medications like semaglutide (Wegovy) and tirzepatide (Zepbound) reduce appetite and slow stomach emptying, helping you eat less. Bariatric surgery, such as the gastric sleeve or gastric bypass, changes the anatomy of the stomach (and, in bypass, the intestine) to durably reduce intake and reshape metabolism.
How the results compare
On medications, trials show meaningful average weight loss: about 15% of body weight over 68 weeks on semaglutide 2.4 mg (STEP 1), and about 20.9% over 72 weeks on the top dose of tirzepatide (SURMOUNT-1). Bariatric surgery typically produces larger, more durable loss: gastric sleeve patients commonly lose 60% to 70% of excess weight in the first year, and gastric bypass patients 70% to 80%.

Durability and the regain question
One honest difference: medication works while you take it, and weight often returns if it is stopped without a durable plan. Surgery changes the anatomy, which is why its results tend to last, though long-term success still depends on habits and follow-up. Neither path is "the easy way," and both work best with real support around them.
Who tends to fit which path
- ◆ Medication may fit when your BMI is in the medical-weight-loss range, you prefer a non-surgical start, or you want to see how you respond first.
- ◆ Surgery may fit when your BMI is higher (generally 35 or 40 and up, or 35+ with a condition like type 2 diabetes), when medication has not been enough, or when durable metabolic change is the goal.
- ◆ For many people the two connect: some start on a GLP-1 and later choose surgery, and some use medication after surgery. The plan can adapt.
The advantage of one practice for both
Because Dr. Eduardo is a bariatric surgeon who also runs the medical weight-loss program, you are not forced to pick a lane at the front door. He can start you on medication with a surgical safety net, or recommend surgery when that is the better long-term fit, and change course as your results come in. We prescribe branded, FDA-approved GLP-1s only, never compounded.
