Comparing your weight loss options
Most people who come to a consultation have already read about every procedure. What is harder to find is how they differ in the ways that matter for a decision: what changes inside you, whether it can be undone, and what it asks of you afterward. That is what this page lays out.

Deciding, not describing
There is no single best weight loss procedure, and anyone who tells you otherwise without knowing your history is selling something. What there is, is a set of real differences between the options: some remove part of the stomach and some remove nothing; some can be adjusted or taken out and some cannot; some leave a device inside you; some need a lot of follow-up and some end on a set date. Once you know which of those differences you care about, the field usually narrows quickly.
This page does not re-explain each procedure. If you want that first, the practice has two overviews, types of bariatric surgery and different types of weight loss surgery explained, and the national references are ASMBS — Bariatric Surgery Procedures and NIDDK — Types of Weight-loss Surgery (National Institute of Diabetes and Digestive and Kidney Diseases).
Whether you qualify for surgery at all is a separate question with its own page: am I a candidate for weight loss surgery?
The options side by side
The table compares how each option works, not how much weight people lose with it. Results depend on the person as much as the procedure, and the pages for each option discuss them with their sources.
On a narrow screen, scroll the table sideways.
| Option | How it is done | What changes inside you | Adjustable or reversible? | Device left inside? | What follow-up involves |
|---|---|---|---|---|---|
| Lap-Band (adjustable gastric band) | Surgery, laparoscopic | A band around the upper stomach limits how much it holds. Nothing is removed and the intestine is not rerouted. | Adjustable, and the band can be removed | Yes: the band, plus an access port under the skin | Band adjustments over time, through the port |
| Sleeve gastrectomy | Surgery, laparoscopic | Most of the stomach is permanently removed, leaving a narrow tube. | Not reversible; not adjustable | No | Long-term nutrition and vitamin follow-up; no adjustments |
| Roux-en-Y gastric bypass | Surgery, laparoscopic | A small stomach pouch is created and the small intestine is rerouted to it. | Difficult to reverse; not adjustable | No | Lifelong nutrition and vitamin follow-up; no adjustments |
| Endoscopic sleeve gastroplasty (ESG, the “Accordion”) | Endoscopic, through the mouth; no incisions | Stitches placed from inside the stomach reduce its volume. Nothing is removed or rerouted. | Not adjustable; the stitches are intended to be permanent. Ask about revision | Stitches only | Staged diet and program follow-up |
| Gastric plication | Surgery, laparoscopic | The stomach is folded in on itself and stitched. Nothing is removed or rerouted. | Not adjustable. Ask your surgeon about reversal | Stitches only | Staged diet and nutrition follow-up |
| Allurion balloon | Swallowed as a capsule; no endoscopy or anesthesia | A fluid-filled balloon temporarily takes up space in the stomach. Nothing is changed permanently. | Temporary by design | Temporarily, while the balloon is in place | The balloon empties itself and passes naturally; no removal procedure |
| Orbera balloon | Placed endoscopically, through the mouth | A fluid-filled balloon temporarily takes up space in the stomach. Nothing is changed permanently. | Temporary by design | Temporarily, while the balloon is in place | A second endoscopy to remove it at the end of treatment |
| GLP-1 medication | Prescription medication | Nothing anatomical. It acts on appetite and fullness signals while you take it. | Can be stopped; its effect depends on continuing it | No | Ongoing prescription and monitoring |
Sources for the table: ASMBS — Bariatric Surgery Procedures; NIDDK — Types of Weight-loss Surgery (National Institute of Diabetes and Digestive and Kidney Diseases); FDA — Weight-Loss and Weight-Management Devices. The balloons and ESG are FDA-regulated devices: FDA Premarket Approval P250023 — Allurion Gastric Balloon System (approved February 20, 2026), FDA Premarket Approval P140008 — ORBERA Intragastric Balloon, FDA Premarket Approval P000008 — LAP-BAND Adjustable Gastric Banding System and FDA De Novo DEN210045 — Apollo ESG and Apollo Revise Systems (July 12, 2022). Gastric plication uses no dedicated device and is not one of the procedures ASMBS lists on its patient page; it is performed less widely than the sleeve or bypass, so ask your surgeon what the evidence for it shows.
Questions that decide between them
In practice a handful of questions do most of the sorting. None has a universal answer, but knowing your own answer before a consultation makes it more useful.
Do you have reflux or heartburn?
This is often the single most decisive fact between a sleeve and a bypass. ASMBS notes that the sleeve may worsen reflux or cause it for the first time, while reflux symptoms usually improve after a gastric bypass (ASMBS — Bariatric Surgery Procedures). Mention reflux, heartburn medication and any hiatal hernia at your first visit. See gastric bypass vs gastric sleeve.
Do you have type 2 diabetes?
Diabetes and other weight-related conditions shape the recommendation as much as weight does, and they are one of the main reasons gastric bypass is discussed. The practice explains the reasoning in gastric bypass and diabetes and bariatric surgery for diabetes, sleep apnea and blood pressure. For the conditions themselves, see obesity and related health conditions.
How much does permanence matter to you?
Some people want an option that removes nothing and can be changed later; others would rather have one decision that does not need revisiting. The band is adjustable and removable, balloons are temporary, and ESG and plication remove no tissue. The sleeve cannot be reversed and the bypass is difficult to reverse (NIDDK — Types of Weight-loss Surgery (National Institute of Diabetes and Digestive and Kidney Diseases)). Both ASMBS and NIDDK also note that the band is used less often in the United States than it once was, which is worth asking about directly.

Have you had weight loss surgery before?
If so, you are choosing a revision, not a first procedure, and the options depend on what was done originally. Start with the revision and weight regain hub, or go straight to Lap-Band revision or gastric bypass revision. Medication after surgery is covered in GLP-1 medications after bariatric surgery.
Are you planning a pregnancy?
Timing matters more than the choice of procedure, but the two interact. See Lap-Band vs gastric sleeve for a future pregnancy and pregnancy and fertility after bariatric surgery.
Medication, a procedure, or both?
These are not opposites. Some people should try medication first; some use it before or after surgery; some find a procedure is the more sustainable answer. The medication hub covers this in full: weight loss medications and GLP-1s before bariatric surgery: bridge or alternative?
What follow-up can you realistically commit to?
Band adjustments, a balloon's fixed treatment period, lifelong vitamins after a bypass, and an ongoing prescription are very different commitments. Be honest with yourself about which one fits your life.
Head-to-head comparisons
Once you have narrowed it to two or three options, these pages compare them in detail. Each is the practice's own article; where the site has several versions of the same comparison, the most complete one is listed.

More on each option
When one option stands out, read its own page before your consultation. These describe the procedure itself: how it is done, who it suits and what the practice's program involves.
After you have narrowed it down
Choosing a procedure is one stage of a longer process. These pages cover what comes before and after it.

Where Dr. Davtyan sees patients
Spanish is spoken at all four offices. The first consultation with Dr. Davtyan is free and commits you to nothing.
Talk it through with a surgeon
A comparison page can narrow the field. It cannot weigh your history, your scans or your priorities, and it cannot tell you which option suits you. That is what the first consultation is for. It is free and commits you to nothing.
