Dr. Reza Keshavarzi narrows the stomach from the inside with an endoscope. He also performs the gastric sleeve and gastric balloon, so your plan is chosen for fit, not because it is the only option on the menu.
Endoscopic sleeve gastroplasty, or ESG, makes the stomach smaller without cutting into the abdomen. Dr. Keshavarzi guides a flexible endoscope through the mouth and places a row of stitches inside the stomach. The stitches fold the stomach wall into a narrower, sleeve-shaped tube.
No tissue is removed and no device stays behind. With less room for food, most patients feel full sooner and eat smaller portions, which supports steady weight loss alongside a structured diet.
No abdominal incisions, so there are no scars on the skin.
The whole stomach stays in place and keeps working.
Each procedure is planned around your health history and goals.

ESG sits between medication and surgery. It suits adults who need more help than diet and medication have given them but who are not ready for, or do not need, a surgical procedure.
You have worked at weight loss with diet, exercise or medication and the results did not last.
You want a smaller stomach without incisions or removing any tissue.
Conditions such as high blood pressure, type 2 diabetes or joint pain are part of the picture.
You are prepared to follow the diet stages and keep your follow-up visits.
Patients with more weight to lose often do better with a gastric sleeve or gastric bypass. Dr. K performs both and will tell you plainly when ESG is not the right tool.
Dr. K performs all three procedures, so the recommendation you hear is based on your health and goals. Here is how they differ.
| Feature | ESG | Gastric Sleeve | ORBERA Gastric Balloon |
|---|---|---|---|
| How it is done | Endoscope through the mouth; stitches fold the stomach | Laparoscopic surgery through small abdominal incisions | Endoscope places a saline-filled balloon in the stomach |
| Stomach tissue removed | No | Yes, most of the stomach | No |
| Abdominal incisions | None | Several small incisions | None |
| What stays inside | Internal stitches that hold the new shape | A smaller stomach; the change cannot be reversed | A balloon, removed after several months |
| Often suits | Moderate weight loss goals without surgery | Larger weight loss goals and long-term durability | A temporary, nonsurgical start |

Dr. Reza KeshavarziMD, FACS, FASMBS
Dr. Keshavarzi, known to patients as Dr. K, is a board-certified surgeon who performs ESG himself. He also performs the gastric sleeve, low BMI Mini Sleeve, teen gastric sleeve, gastric bypass and ORBERA gastric balloon, and he oversees our medical weight loss program.
That range matters when you are choosing a procedure. Because he offers every option, his recommendation follows your health rather than a single procedure.
Patients also get direct access. Dr. K stays in touch from his personal cell phone before and after the procedure.
You meet Dr. Keshavarzi to talk through your health history, past weight loss attempts and goals. You leave knowing whether ESG fits, how it compares with your other options and what happens next.
Medical clearances come first, and a pre-procedure diet is required. If you use weight loss injections, you stop them at least two weeks before the procedure. Our team supports you through each step.
ESG is performed under anesthesia with an endoscope, with no abdominal incisions. Dr. K places the stitches that reshape the stomach, and you rest under observation until you are ready to go home.
Eating moves in stages from liquids to soft foods to regular meals, guided by our diet plans. Many patients return to work within four to seven days and avoid lifting more than 20 pounds until cleared. Follow-up visits track your progress and adjust your plan.

Our office is in South Miami, a drive down the Florida Turnpike or I-95 from Coral Springs. We plan your care so each trip counts, and part of the preparation can happen closer to home.
Required tests and clearances can be done at a facility near you or with our recommended doctor in Miami.
After your consultation, you can reply to our text messages for guidance on what comes next.

"Provided his cell phone to make sure he could be reached at all hours."
"The doctor was very straightforward and honest and extremely professional."
"Extremely knowledgeable, responsive, and genuinely committed to patient care."
Reviews describe patients' experience with Dr. K and our team across our weight loss procedures. Individual results vary.
Your ESG cost depends on your health history, the testing you need and the plan Dr. K recommends, so we give you an exact figure after your consultation.

Straight answers to what patients ask us most about endoscopic sleeve gastroplasty.
ESG is an endoscopic procedure, not traditional surgery. The endoscope passes through the mouth, so there are no incisions on the abdomen and no part of the stomach is removed. At our practice it is performed by Dr. Keshavarzi, a board-certified surgeon with fellowship training in bariatric surgery.
Yes, ESG does not close the door on surgery. Because the stomach stays intact, a patient who needs more weight loss later can still be evaluated for a gastric sleeve or another procedure. Dr. K performs these surgeries as well, so the same surgeon can guide that decision.
Yes. Weight loss injections must be stopped at least two weeks before your procedure. Tell us about every medication you take so Dr. K can plan the timing with you.
Yes. Required tests and medical clearances can be done at a facility closer to home or with our recommended doctor in Miami. Your procedure date can be set as soon as the required results are complete.
ESG reduces how much the stomach holds, so most patients feel full sooner and eat smaller portions. Hunger does not disappear, which is why the post-procedure diet stages and follow-up visits matter. Our team helps you adjust what and how you eat as you heal.
Procedure dates are often available within the same month. How quickly you are scheduled depends mainly on how fast your required tests and clearances are completed.
Find out whether ESG, a gastric sleeve or another option fits your goals, and leave with a clear plan.
