You think we'll blame your eating. We won't.
You probably already heard "just track your protein." You did. It didn't change anything. That's because the problem is usually physical, and a food log doesn't shrink a stretched outlet.
"I can eat anything now."
The opening between your pouch and your intestine stretches over the years. When it does, food passes straight through, fullness never arrives, and hunger comes back. That's anatomy, not character.
"I regained most of it."
A stretched pouch, a widened outlet, or a channel that reopened into the old stomach can all undo what the bypass did. Each one can be found with a scope and imaging.
"My diabetes came back."
The metabolic effect of a bypass can fade as the anatomy changes. When A1c climbs again, or blood pressure and reflux return, that's a reason to look inside, not a reason to give up.
"It hurts when I eat."
Pain, vomiting, regurgitation, and ulcers after a bypass have names: marginal ulcer, stricture, a blind limb that fills with food, a fistula. Most have a specific repair.
No restriction anymore? There's a reason, and often a fix.
A gastric bypass builds a small pouch at the top of the stomach and connects it straight to the small intestine through a narrow outlet. The pouch limits how much you eat, the outlet keeps food from rushing through, and the rerouting quiets hunger hormones and helps blood sugar. Over the years, each of those parts can change. Dr. El Djouzi finds which one did.
The outlet stretched
The connection between pouch and intestine (the gastrojejunal anastomosis) is meant to be narrow. Over years it can widen to several times its original size. This is the single most common reason a bypass "stops working."
The pouch stretched
The small stomach pouch built at your first surgery can enlarge. A bigger pouch means more food before fullness, and less of the hormone signal that kept hunger quiet.
Something else opened up
A channel between the pouch and the bypassed stomach (gastrogastric fistula), a blind limb that fills with food, an ulcer at the connection, or a narrowing. These cause symptoms as often as regain.
Each of these shows up on an upper endoscopy, an upper GI X-ray, or both. That's why the evaluation comes before any recommendation.
One surgeon. Every revision option. Including not operating.
Dr. El Djouzi is board-certified in surgery and in obesity medicine, and fellowship-trained in advanced endoscopy. He offers the full revision spectrum, from a scope through the mouth to a full conversion. Which one fits you, if any, comes from the evaluation, not from a brochure.
GLP-1 medication with your bypass
Semaglutide or tirzepatide, prescribed and managed by the surgeon himself. Sometimes the first step. Sometimes the only step. Often paired with a procedure below.
Outlet tightening (TORe)
A scope through the mouth places sutures to narrow a stretched outlet and, when needed, reduce the pouch. Usually home the same day. Reaches less than surgery, and that's the point for the right patient.
Pouch and outlet revision
Small incisions, usually robotic. Rebuilds an enlarged pouch or a widened connection. Also used for a blind limb, a fistula, or a stricture that a scope can't handle.
Distalization or conversion
Lengthening the bypass for more metabolic effect, or converting to a duodenal switch or SADI-S when diabetes and regain need more than the original operation delivered.
We will analyze your current bypass anatomy. Then we tell you what fits.
Bring your old operative report, if available. If you don't have it, that's fine. We can request it for you.

Sofiane El Djouzi, MD, FACS, FASMBS
Most bypass patients with regain get eight minutes, a handout, and a referral to a dietitian. Dr. El Djouzi reads your operative report before you walk in, scopes you himself, and does every kind of revision there is, so he has nothing to steer you toward.

Dual board-certified bariatric surgeon with 15+ years of experience and 2,400+ procedures. Fellowship-trained in metabolic surgery and in advanced endoscopy.

Straight answers
Can a gastric bypass really be revised?
Yes, often. A bypass can be tightened with a scope through the mouth, revised surgically at the pouch or the outlet, lengthened for more metabolic effect, or converted to a different operation. Which one, if any, depends on your anatomy, your original operation, and your symptoms. Not everyone who calls is a candidate. That's what the evaluation is for.
Will you just tell me it's my fault for eating wrong?
No. You've probably already been told to "track your protein." If your outlet has stretched to three times its original size, a food log won't shrink it. We look at the anatomy first. Habits matter and we'll talk about them, but they're never used as a reason to send you home without looking.
Is a second surgery on scar tissue riskier?
Yes. A revision carries more risk than a first operation. Scar tissue, altered anatomy, and old staple lines make it harder, and the complication rate is higher than for a first-time bypass. That's why the evaluation is thorough, why the least invasive option that can work is chosen first, and why you want a surgeon who does revisions regularly with robotic tools and endoscopy training. Dr. El Djouzi walks you through the specific risks for your case before anything is scheduled.
Does insurance cover it? Is it true you only get one surgery?
Coverage depends on your plan and on medical necessity. Revisions for a documented complication (ulcer, stricture, fistula, severe reflux, recurrent diabetes) are approved more often than revisions for weight alone. "You only get one bariatric surgery" is a clause in some plans, not a universal rule, and many plans have no such limit. We verify your benefits before you commit to anything. Self-pay pathways exist for plans that exclude it.
What does it cost out of pocket?
Published self-pay ranges around the country run roughly $15,000 to $35,000 for a surgical revision and roughly $5,000 to $15,000 for an endoscopic procedure. Your number depends on what's actually needed and where it's done, and it's verified per case after evaluation. You get a written figure before you decide anything.
Do I need my original operative report?
It helps, and it isn't required to start. The report tells us the pouch size, the limb lengths, and how the outlet was built. If you don't have it, we request it from the hospital with your signed release. Bring whatever you have to the call, even if it's just the surgeon's name and the year.
I tried the weight-loss shots after the regain. Is it too late, or can they be combined?
Wegovy, Zepbound, Ozempic. Not too late, and yes, they can be combined. Medication is often the first step and sometimes the only one. If your anatomy is the reason the drug stalled, addressing the anatomy can let the medication do its job. Dr. El Djouzi is board-certified in obesity medicine and manages these prescriptions himself, so the plan comes from one person.
Endoscopic vs surgical. What's the difference?
Endoscopic (TORe) goes through the mouth with a scope. No incisions, usually home the same day. It tightens a stretched outlet and can reduce the pouch. Surgical revision goes through small incisions, usually robotic, and rebuilds the pouch or outlet, lengthens the bypass, or repairs a complication. Endoscopic is less invasive and reaches less. Which one fits you depends on what the evaluation shows.
What is a "pouch reset"?
A diet, not a procedure. Usually a week or two of liquids and soft foods. It doesn't shrink your pouch or your outlet. If it helps you restart habits, fine, but it isn't a treatment for stretched anatomy. Pouch resizing is a real procedure. They aren't the same thing, and the names get confused online.
My surgery was years ago, somewhere else. Can you still help?
Yes. Most revision patients had their bypass with another surgeon, often ten or twenty years ago, with no follow-up since. We request your records and start from your current anatomy. Where and when it was done doesn't disqualify you.
Five questions. Under a minute. Then ten minutes with the surgeon.
Ask him the thing you've been wondering since the weight came back. Whether your bypass can be fixed, what it would take, and what insurance is likely to cover. If revision isn't the answer for you, he'll say so.
No fee. No obligation. Most calls happen within the week.
