Board-certified, fellowship-trained bariatric surgeon Dr. Reza Keshavarzi finds out why your bypass stopped working before he recommends revision surgery, medication or both.
Gastric bypass revision is a second operation for patients whose weight loss surgery no longer controls hunger and weight as it once did. The term covers two different situations.
Years later, parts of a bypass can change. Revision targets only what changed.
Patients who had a gastric sleeve often ask whether a bypass is the next step, usually because of regain or ongoing reflux. Dr. K performs both operations, so he can judge whether converting suits your anatomy.
Regain after a bypass is common and does not mean you failed. The evaluation shows whether the cause is anatomical, behavioral or both.
Revision surgery is one tool, not the only one. Dr. K builds plans from GLP-1 medication, surgery, nutrition coaching and psychological support, often combining them.
| Option | What It Works On | When It Tends to Fit |
|---|---|---|
| Revision surgery | A stretched pouch or outlet, or a bypass that has lost its effect | Testing shows a physical change behind the regain |
| GLP-1 medication | Appetite and hunger signals | Anatomy looks sound, or as support around surgery |
| Nutrition and psychological support | Grazing, meal patterns and emotional eating | Every plan, with or without surgery |
When surgery is planned, weight loss injections are stopped at least 2 weeks before the procedure.
Dr. K reviews your original operation and weight history. You leave knowing your options and next tests.
An upper endoscopy, or EGD, shows the size of your pouch and outlet. Medical clearances follow before a surgery date is set.
A pre-surgery diet prepares your body, with our team supporting you throughout.
Dr. K performs the revision chosen for your anatomy. Patients typically return to work in 4 to 7 days and avoid lifting more than 20 lbs while they heal.
Our surgical packages include follow-up appointments for the first year, and Dr. K contacts patients from his own cell phone.
Dr. Reza Keshavarzi, MD, FACS, called Dr. K by his patients, is a board-certified bariatric surgeon and a Diplomate of the American Board of Surgery. He trained in surgery at Jackson Memorial Hospital and completed a fellowship in laparoscopic, bariatric and robotic surgery at Jackson South Medical Center.
Because Dr. K performs gastric bypass, gastric sleeve, endoscopic sleeve gastroplasty and ORBERA balloon procedures and oversees medical weight loss, he weighs every route rather than defaulting to one.

Revision pricing depends on what your anatomy needs, so your quote follows the evaluation. Cherry financing turns the cost into monthly payments, and cards are accepted for any remaining balance.

Yes. A Roux-en-Y bypass can be revised when the pouch or outlet has stretched or the bypass has lost some of its effect. Your endoscopy and evaluation show whether revision is the right step or whether medication and nutrition support should come first.
The most common candidates have regained a meaningful share of their weight, lost less than expected, or noticed hunger and portions returning. Dr. K confirms candidacy after reviewing your history and test results.
Your price depends on which revision your anatomy needs, so it is set after the evaluation. Cherry financing offers 24 months at 0% interest, with monthly payments as low as $320.
Yes. Dr. K evaluates a bypass performed elsewhere the same way, starting with an endoscopy and your history. Records from the original operation help when you have them.
