Laparoscopic Roux-en-Y gastric bypass with Dr. Reza Keshavarzi, a fellowship-trained bariatric surgeon who stays reachable on his own cell phone from your first visit through recovery.
Gastric bypass, or Roux-en-Y gastric bypass, turns the working stomach into a small pouch and connects that pouch farther down the small intestine.
Dr. Keshavarzi performs it laparoscopically, through several small incisions with a camera and slim instruments. The pouch fills after a few bites, so portions stay small without a daily fight against hunger.
Food then skips most of the stomach and the upper small intestine, which lowers the calories you absorb and shifts the hormones tied to appetite and blood sugar.
For Hollywood patients, the whole program runs through our South Miami office, with one surgeon overseeing testing, surgery and follow-up.
Bypass is designed for adults with obesity whose weight is affecting their health. Dr. K conducts every consultation himself and recommends an operation only after reviewing your history and goals.
Bypass changes the hormones that regulate blood sugar, so it is often considered when diabetes comes with excess weight.
The pouch makes little acid, so bypass is often chosen over the sleeve when reflux is constant.
Sleep apnea, high blood pressure and joint pain tend to ease as weight comes down.
Diets, programs or medication worked for a while, then the pounds came back.
You want a longer-lasting plan than weekly injections.
Smaller meals, protein first and daily vitamins will become part of everyday life.
Not sure bypass is your fit? Dr. Keshavarzi also performs the gastric sleeve, the low BMI Mini Sleeve, endoscopic sleeve gastroplasty (ESG) and the ORBERA gastric balloon, and he oversees medical weight loss.
Book a ConsultationMost patients researching bypass are also weighing the gastric sleeve. Dr. Keshavarzi performs both, so he can compare them for your health without a stake in either.
| Gastric Bypass | Gastric Sleeve | |
|---|---|---|
| Approach | Laparoscopic, through small incisions | Laparoscopic, through small incisions |
| Stomach | A small pouch is made and the rest stays in place, bypassed | Most of the stomach is removed, leaving a narrow tube |
| Small intestine | Rerouted to the new pouch | Unchanged |
| Often chosen for | Reflux and type 2 diabetes | A simpler operation with no rerouting |
| Supplements | Lifelong, including B12, iron and calcium | Lifelong, usually a lighter routine |

Dr. Keshavarzi, Dr. K to his patients, leads our surgical team and brings decades of experience in bariatric and minimally invasive surgery. He performs every surgical and endoscopic weight loss option we offer, from gastric bypass to the gastric balloon.
After surgery, patients reach him on his personal cell phone. Questions during recovery go straight to the surgeon who operated on you.
Your surgery date is set as soon as your required tests are complete, so preparation moves at your pace.
Dr. K reviews your weight history, health conditions and medications, explains whether bypass or another option fits, and walks you through cost and financing.
You complete medical clearances and an EGD. Tests can be done at our clinic or an outside facility, and results from our recommended doctor typically return within 48 hours.
A required pre-surgery diet prepares your body for the operation. If you use weight loss injections, you stop them at least two weeks before surgery.
Dr. Keshavarzi creates the pouch and reconnects the small intestine through small incisions. You recover in the hospital before heading home.
Many patients return to work within 4 to 7 days. Lifting over 20 pounds stays off limits while you heal.
You move through staged diet plans, start lifelong vitamins and keep regular follow-up visits with Dr. K.
Your total depends on your health, the testing you still need and where it is done. Dr. K reviews your figure at the consultation, before you choose a date.
