Dr. Reza Keshavarzi, a fellowship-trained bariatric surgeon, performs your endoscopy himself, so the revision he recommends is based on what he sees inside your pouch.
A gastric bypass revision is a second procedure that adjusts an existing Roux-en-Y gastric bypass so it controls hunger and portions again. Over the years, the small stomach pouch or the outlet between the pouch and the intestine can stretch, and meals stop producing the early fullness the bypass once created.
A revision narrows or resizes those structures, or changes how much intestine food bypasses, depending on what your endoscopy shows. Some revisions are done through an endoscope with no incisions. Others are laparoscopic, through a few small incisions.
Dr. Keshavarzi performs gastric bypass, endoscopic sleeve gastroplasty and diagnostic endoscopy himself, so the surgeon who reviews your anatomy is the surgeon who plans your revision. Patients from Pembroke Pines see us at our South Miami office.
Revision is considered when a bypass no longer controls hunger or portion size and steady changes to eating and activity have not brought that control back.
Steady regain after reaching your lowest weight, often as portions creep up without a change in habits.
Eating larger meals before feeling satisfied, a common sign that the pouch or outlet has stretched.
Weight loss that stopped well short of the goal you and your surgeon set before the original bypass.
Snacking through the day because meals no longer hold you the way they did in the first year.
Ongoing discomfort after eating that calls for a surgeon to look directly at your anatomy.
For some patients, medication and nutrition support are the better first step. An honest evaluation tells you which route fits.
Dr. Reza Keshavarzi, MD, FACS, FASMBS
Dr. Keshavarzi, known to patients as Dr. K, is a board-certified bariatric surgeon with decades of experience in bariatric and minimally invasive surgery. He completed a fellowship in laparoscopic, bariatric and robotic surgery at Jackson South Medical Center after his surgical residency at Jackson Memorial Hospital.
Revision work depends on reading altered anatomy correctly. Because Dr. K performs bypass, endoscopic suturing and endoscopy himself, he matches the approach to what he finds.
Speaking with Dr. K: he answers common questions about weight loss surgery.
The right revision depends on what has changed since your original surgery. Dr. Keshavarzi recommends an approach only after reviewing your endoscopy and history with you.
| Option | What It Does | Approach | Often Considered When |
|---|---|---|---|
| Endoscopic outlet reduction | Sutures placed through an endoscope narrow a widened outlet and can reduce the pouch. | No incisions | The outlet or pouch has stretched and the rest of the bypass is sound. |
| Laparoscopic pouch or outlet revision | The pouch or the connection to the intestine is resized surgically. | Small incisions | Stretching is more marked, or endoscopic repair is not suitable. |
| Limb-length revision | The length of bypassed intestine is changed to alter how much food is absorbed. | Small incisions | Regain continues even though the pouch and outlet are a normal size. |
| GLP-1 medication with nutrition support | Weekly medication reduces appetite, paired with a personalized eating plan. | No procedure | Regain is milder, or as support before or after a revision. |
Our team on combining GLP-1 medications, bariatric surgery and lifestyle support.
Weight regain after a bypass does not always call for another operation. We offer medical weight loss and weight loss injections alongside surgery, so your plan can start with medication, move to a revision, or combine the two.
If you use weight loss injections now, they are stopped at least 2 weeks before surgery. We plan that pause with you.
Each step is set up so patients traveling from Pembroke Pines make fewer trips and always know what comes next.
He reviews your original surgery, your weight history since, how you eat now and your health conditions, then explains which options fit and why.
An endoscopy shows the size of your pouch and outlet. One from the last 5 months is accepted, and testing can be done with us or at a facility nearer home.
A pre-surgery diet is required. How soon your date is set depends on how quickly your clearances are complete.
Dr. Keshavarzi performs the procedure using the approach agreed at your consultation, endoscopic or laparoscopic.
After laparoscopic surgery, our patients typically return to work in 4 to 7 days and avoid lifting more than 20 lbs early on.
He has been there the whole process, provided his cell phone to make sure he could be reached at all hours.

Revision pricing depends on the approach, so Dr. Keshavarzi quotes it after your evaluation rather than from a fixed list. You receive the cost and your financing options before you decide.
When Dr. Keshavarzi performs your endoscopy, it is included in your procedure cost. A $750 hospital fee applies.
Financing through Cherry includes 24 months at 0% interest, with monthly payments as low as $320.
Debit and credit cards are accepted for any remaining balance on your surgery.
Straight answers to what patients ask most before a revision consultation.
The usual signs are steady weight regain, eating larger portions before you feel full, or weight loss that stopped early. An endoscopy shows whether your pouch or outlet has stretched, which is the clearest guide. Dr. Keshavarzi reviews those findings with you before recommending any option.
Often, yes. When the outlet or pouch has stretched and the rest of the anatomy is sound, sutures placed through an endoscope can narrow it with no abdominal incisions. When the changes are larger, a laparoscopic revision may be the better fit.
Yes, for many patients. We offer weight loss injections as part of medical weight loss, on their own for milder regain or alongside a revision. If you are heading to surgery, injections are stopped at least 2 weeks before your procedure.
It depends on the approach. After laparoscopic surgery, our patients typically return to work in 4 to 7 days and avoid lifting more than 20 lbs during early recovery. Your plan spells out your own timeline and diet stages.
