Dr. Reza Keshavarzi, a fellowship-trained bariatric surgeon, starts every revision by finding out what changed in your bypass, then builds a plan around that answer in our South Miami office.
Gastric bypass revision is a follow-up operation on a Roux-en-Y gastric bypass that no longer controls appetite and weight the way it once did. It does not repeat the first surgery. It corrects the specific part of your bypass that has changed.
That is why the first job is diagnosis. An upper endoscopy and a review of your history show which of these three areas is involved, and the answer decides the operation.
The small stomach pouch created during your bypass can enlarge with time. Reducing its size brings back the early fullness that made portions easy to control.
The opening where the pouch joins the small intestine can stretch, so food moves through quickly and hunger returns early. Tightening that connection slows emptying again.
In selected cases, adjusting how much small intestine the food bypasses can strengthen the metabolic effect. Dr. K considers this only when your evaluation supports it.
Most patients who come to us about a revision had a bypass that worked well for several years. Something shifted, and they want to know whether it can be corrected.
Regain after a bypass is common and it is not a personal failure. The evaluation separates anatomical causes from habits and appetite so your plan treats the real problem.
A revision is one tool, not the only one. Dr. K builds plans from GLP-1 medication, bariatric surgery, nutrition coaching and psychological support, in the combination your evaluation calls for, with concierge follow-up after.
| Option | What It Targets | Dr. K May Suggest It When |
|---|---|---|
| Revision surgery | An enlarged pouch, a stretched connection or a bypass that has lost its effect | The endoscopy shows a change in your anatomy behind the regain |
| GLP-1 medication | Appetite and hunger signals | Your anatomy looks sound, or to support a revision before or after surgery |
| Nutrition coaching | Portion habits, grazing and protein intake | Every plan, surgical or not |
| Psychological support | Emotional eating and lasting behavior change | Eating patterns are part of what changed |
When surgery is in your plan, weight loss injections are stopped at least 2 weeks before the procedure.
Each step answers a question before the next one starts, so surgery is only scheduled once the cause is clear and you are medically ready.
Dr. K conducts the consultation himself. He goes over your original operation, your weight since then and what you have already tried, and you leave knowing which options are realistic for you.
An upper endoscopy shows your pouch and connection as they are today. Dr. K can perform it, or you can have it done elsewhere, and medical clearances follow.
A pre-surgery diet is required and readies your body for the operation. Our team supports you through every part of the preparation.
Dr. K performs the revision chosen for your anatomy. After our bariatric procedures, patients typically return to work in 4 to 7 days and avoid lifting more than 20 lbs while they heal.
Dr. K stays reachable after surgery and contacts patients from his own cell phone. Nutrition guidance and check-ins continue as you settle into your new routine.
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.
A good revision starts with knowing every alternative. Dr. K performs gastric bypass, gastric sleeve, endoscopic sleeve gastroplasty and ORBERA gastric balloon procedures and oversees medical weight loss, so your plan is built from the full range rather than a single default.
These reviews come from our gastric sleeve and weight loss patients. They describe the part of care that matters most after any bariatric surgery: a surgeon who stays involved for years.
It's been a year since my gastric sleeve surgery. He has been there for me from the beginning of my journey until now.

A revision can mean a small correction or a larger change to your bypass, so the price follows your evaluation. Dr. K's team gives you the full quote and walks through financing once the plan is set.
Cherry financing is accepted for surgery, and debit or credit cards can cover any remaining balance.
Apply for Cherry financing and review your payment options before surgery.Our office sits on SW 62nd Place in South Miami, so local patients handle consultations, planning and follow-up visits in one place close to home. After a revision, check-ins happen in the same office where your plan began.
Testing can stay convenient too. The required tests can be done at our clinic or at an outside facility, whichever fits your schedule better.
Revision is worth discussing if you have regained a meaningful share of your weight after gastric bypass, lost less than expected, or still have symptoms that started after the first operation. Dr. K decides with you based on what the endoscopy and evaluation show about your pouch and outlet, plus your eating patterns and health history. When medication and nutrition support are the better first step, we tell you so.
Usually more than one thing is involved. The pouch or the opening into the small intestine can widen over the years, so meals get larger and fullness fades sooner. Eating habits such as grazing, appetite signals and emotional eating also play a part, which is why the evaluation looks at both anatomy and habits.
Yes. An upper endoscopy, or EGD, is required because it shows how your pouch and connection look today. It can be performed by Dr. K or done elsewhere, and medical clearances are completed before a surgery date is set.
Yes. A bypass done elsewhere is evaluated the same way, starting from how your anatomy looks today. Records from your original operation are helpful when you have them, but the endoscopy and testing are what shape the plan.
Dr. K completed a fellowship in laparoscopic, bariatric and robotic surgery, and minimally invasive surgery is central to his work. The approach for your revision depends on your anatomy and your first operation. He explains the plan for your case before you decide.
It depends on which revision you have. After our bariatric procedures, patients typically return to work in 4 to 7 days and avoid lifting more than 20 lbs during early healing. Dr. K confirms your own timeline before surgery.
For some patients, yes, especially when the endoscopy shows the bypass anatomy is still sound. Medication can also support a revision before or after surgery. If surgery is part of your plan, weight loss injections are stopped at least 2 weeks beforehand.
Sit down with Dr. K, learn why your weight has shifted, and leave with a plan that may include revision surgery, medication, nutrition support or a mix of all three.
