Dr. Reza Keshavarzi, a fellowship-trained bariatric surgeon, starts with an endoscopy to learn why weight returned after your bypass, then builds a plan around what he finds.
A Roux-en-Y gastric bypass creates a small stomach pouch and connects it directly to a limb of the small intestine. Over the years, the pouch or the opening between pouch and intestine, called the outlet, can stretch. Portions grow, fullness fades and weight can return.
Revision is any procedure that changes the original bypass so it works the way it was built to. That can mean narrowing the outlet from the inside with an endoscope, resizing the pouch, or adjusting the intestinal limbs. For every Miramar patient, Dr. K's first step is the same: look before deciding.
Revision is worth evaluating when one or more of these sound familiar. A stretched pouch or outlet is a mechanical change, not a lack of effort.
Pounds coming back after your low point, even while you follow your eating plan.
You can finish meals that once filled you after a few bites.
Fullness fades quickly after meals and snacking creeps back into the day.
Blood sugar, blood pressure or sleep apnea moving back toward where they were before surgery.
Another surgeon performed your original operation and you want a fresh evaluation.
GLP-1 injections alone are no longer moving the scale and you want to know whether anatomy is part of the reason.
The endoscopy shows the size of your pouch and outlet, and that finding narrows the choices. Which one fits depends on your anatomy, your health and your goals.
Sutures placed through an endoscope narrow a stretched outlet with no external incisions. Suited to an outlet that has widened while the pouch stays close to its original size.
A minimally invasive operation that resizes an enlarged pouch or rebuilds the connection to the intestine. Considered when the pouch itself has grown.
Changes how much intestine food bypasses, which targets absorption rather than portion size. Reserved for specific situations after careful review.
GLP-1 weight loss injections paired with nutrition guidance, used on their own or alongside a procedure.
Weight regain after a bypass rarely has a single answer. Dr. K combines tools when the combination works better than any one of them, and he adjusts the plan as your results come in.

Dr. Keshavarzi is a board-certified bariatric surgeon and a Diplomate of the American Board of Surgery. He completed his surgical residency at Jackson Memorial Hospital and a fellowship in laparoscopic, bariatric and robotic surgery at Jackson South Medical Center.
He performs gastric bypass, gastric sleeve and endoscopic sleeve gastroplasty, so he weighs a revision with both the surgical and the endoscopic paths in view. Patients reach him directly, often on his personal cell phone.

Each step answers a question the next one depends on, so nothing is decided before the evidence is in.
Dr. K reviews your original operation, weight history, eating patterns and goals.
An EGD shows the pouch and outlet directly. Dr. K can perform it or review a recent one done elsewhere.
Medical clearances and a pre-surgery diet come first. GLP-1 injections stop at least two weeks before surgery.
Recovery depends on the revision type. After laparoscopic procedures, patients typically return to work in 4 to 7 days and avoid lifting over 20 lbs.
Ongoing visits, nutrition guidance and direct access to Dr. K keep the result on track.
Revision pricing depends on the procedure your evaluation points to, so we quote it after the EGD rather than guess in advance. When Dr. K performs the endoscopy, it is included in the overall procedure cost, with a separate hospital fee.
Financing is available through Cherry for patients who prefer to spread the cost over time.
Yes. A gastric bypass can be revised years after the original operation. The right approach depends on what an EGD shows about your pouch and outlet, which is why the evaluation comes before any recommendation.
Cost depends on whether your plan is endoscopic, surgical or medication based, so we quote it after your evaluation. Cherry financing is available, including 24 months at 0% interest.
Approval starts with a consultation and an EGD. Dr. K walks you through each remaining requirement once he knows which option fits.
Yes. Many revision patients had their first operation elsewhere. Dr. K evaluates your anatomy as it is today, and the EGD shows what older records may not.
For some patients, yes. Weight loss injections can quiet appetite on their own or support a revision. Dr. K decides with you whether medication, a procedure or both makes sense.
