Dr. Reza Keshavarzi narrows your stomach from the inside with sutures placed through an endoscope, and because he also performs the sleeve, bypass and balloon, you get an honest comparison before you choose.
Endoscopic sleeve gastroplasty is a weight loss procedure that makes the stomach smaller without removing any of it. While you sleep under general anesthesia, Dr. K guides a flexible endoscope through the mouth and places full-thickness sutures along the stomach wall. Drawing them tight gathers the stomach into a narrower, sleeve-shaped tube.
The smaller stomach fills faster and empties more slowly, giving new eating habits time to settle in.
Dr. K is a member of the Society of American Gastrointestinal and Endoscopic Surgeons, and he also operates laparoscopically. The surgeon who reviews you for ESG can offer a sleeve or bypass if your health points that way.
ESG is for adults living with obesity who need more help than diet and exercise have given them but do not want an operation. It works alongside diet changes and regular follow-up, and Dr. K confirms candidacy after reviewing your health history.
You have lost weight before and watched it return. ESG adds a physical limit that willpower alone cannot supply.
You want a real change to your stomach without cuts on your abdomen or removing tissue.
Blood pressure, blood sugar, sleep apnea or joint pain are telling you it is time to act.
You lost weight on weight loss injections and want a longer-term tool as you reduce or stop them.
ESG not the right fit? Dr. K also performs the gastric sleeve, the low BMI Mini Sleeve, gastric bypass and the gastric balloon, and he oversees medical weight loss.
Dr. K performs all three procedures. The comparison you hear at your consultation is about your health and goals, never about which procedure a single office happens to offer.
| Factor | ESG | Gastric Sleeve | ORBERA Gastric Balloon |
|---|---|---|---|
| How it is done | Endoscope through the mouth | Laparoscopic surgery through small abdominal incisions | Endoscope through the mouth |
| The stomach | Folded inward with sutures and kept whole | Most of the stomach is removed | A soft balloon fills part of the space |
| Incisions | None | Several small ones | None |
| Permanence | Designed to last, and can be revised or converted later | Not reversible, since tissue is removed | Temporary, removed after about six months |
| Often suits | Patients who want lasting help without an operation | Patients whose health calls for a larger surgical change | Patients who want a short-term start |
Medical weight loss, including weight loss injections, is a fourth path. Some patients use it on its own, and others pair it with a procedure for extra support.
MD, FACS, FASMBS. Board-certified bariatric surgeon
Dr. Keshavarzi, known to patients as Dr. K, is the lead surgeon at Miami VIP Surgery, with decades of experience in bariatric and minimally invasive surgery. He trained close to home: his surgical residency was at Jackson Memorial Hospital and his fellowship in laparoscopic, bariatric and robotic surgery at Jackson South Medical Center.
Patients reach him directly. He stays in touch from his personal cell phone through preparation and recovery, so questions do not wait in a queue.
Our team supports you through each step of preparation. How soon your procedure is scheduled depends mainly on how quickly your required tests are completed.
Dr. K reviews your weight history, medications, health conditions and goals. You leave knowing whether ESG fits, how it compares with your other options and what it will cost.
Medical clearances and an upper endoscopy, or EGD, are part of your workup. Tests can be done with our recommended doctor, who usually returns results within 48 hours, or at a facility you choose. An EGD from the last five months is accepted.
A pre-procedure diet prepares your body for the endoscopy. If you use weight loss injections, they are stopped at least two weeks ahead, and our team confirms any other medication changes.
Under general anesthesia, Dr. K places the sutures through the endoscope. There are no incisions to heal, and many patients go home the same day.
You move from clear liquids to purées and soft foods before regular meals, following our diet plans. Dr. K sets your activity and lifting limits for each stage.
Regular check-ins track your weight, nutrition and routine. Protein, daily walking and strength training help you keep the results ESG makes possible.
These Google reviews come from patients across Dr. K's weight loss procedures. The same team and follow-up support every ESG patient.

Your ESG price depends on your health, the testing you still need and your plan. Dr. K gives you an exact figure after your consultation, rather than an estimate that might change later.
Cherry is accepted, and debit and credit cards cover any remaining balance. See our financing details.
ESG is an endoscopic procedure rather than an open or laparoscopic operation. There are no incisions and no part of the stomach is removed. It is still performed under general anesthesia by a surgeon, and Dr. K is trained in both endoscopic and laparoscopic techniques.
Your ESG price depends on your health, the testing you still need and your plan, so Dr. K gives you an exact figure after your consultation. We can email your pricing so you can review it at home. Financing through Cherry is available, including 0% interest for 24 months.
Yes. Weight loss injections must be stopped at least two weeks before your procedure, and Dr. K plans that timing with you. If your plan calls for it, our medical weight loss program can keep supporting you after ESG.
Patients typically return to work 4 to 7 days after the procedure. Avoid lifting more than 20 pounds until Dr. K clears you. Your exact timeline depends on your job and how you feel as you move through the diet stages.
The 20-20-20 rule is a common reminder after stomach-reducing procedures to eat slowly, chew every bite well and keep drinks apart from meals. The exact numbers vary from program to program. Dr. K and our diet plans give you specific eating guidelines for each stage after your ESG.
Because ESG removes no tissue, the stomach can usually be revised or converted to another procedure, such as a gastric sleeve, if your needs change. Dr. K performs both procedures, so the same surgeon can guide that decision with you.
Patients from Hialeah are seen at our South Miami office, reachable by the Palmetto Expressway. Meet Dr. K, ask every question you have and find out whether ESG is the right tool for you.
