Roux-en-Y gastric bypass performed by Dr. Reza Keshavarzi, a fellowship-trained laparoscopic and bariatric surgeon who also offers the sleeve, ESG and medical weight loss, so your plan fits your health.
Gastric bypass, also called Roux-en-Y gastric bypass, changes both how much you can eat and how your body handles food. Dr. K creates a small stomach pouch and connects it directly to a lower part of the small intestine, so food skips most of the stomach and the first section of the intestine.
He performs the operation laparoscopically, through small incisions with a camera and slim instruments. That approach is what his fellowship in laparoscopic, bariatric and robotic surgery at Jackson South Medical Center trained him to do.
The new pouch holds a few ounces, so you feel full after small, protein-first meals.
Food bypasses part of the intestine, which lowers how many calories your body absorbs.
Rerouting changes gut hormones that drive appetite and blood sugar, which is why bypass is often discussed for type 2 diabetes.
Most people searching for gastric bypass are also weighing the sleeve. Dr. K performs both, so he can recommend the one that matches your health instead of the only one on offer.
| Gastric Bypass | Gastric Sleeve | |
|---|---|---|
| What changes | A small pouch is created and the intestine is rerouted to it | About 80% of the stomach is removed, leaving a narrow tube |
| How it works | Smaller portions, fewer calories absorbed and hormone changes | Smaller portions and lower hunger hormone levels |
| Often considered for | Significant acid reflux, type 2 diabetes or a higher starting weight | Patients who want a simpler operation with no intestinal rerouting |
| Surgical approach | Laparoscopic, small incisions | Laparoscopic, small incisions |
| Long-term care | Lifelong vitamins and a protein-first eating plan | Lifelong vitamins and a protein-first eating plan |

It depends on your starting weight, your metabolism and how closely you follow the post-op diet. Weight usually comes off fastest in the first months after surgery. Dr. K gives you a realistic timeline for your own body at the consultation.
Dr. K may suggest another path if a medical condition makes surgery unsafe right now, if a planned pregnancy is close, or if lifelong vitamins and diet changes are not realistic for you. Active substance use and untreated eating disorders also need care first. Many patients who are not ready for bypass do well with the sleeve, ESG, a balloon or medical weight loss.
Coverage depends on your specific plan and its requirements. Our team reviews your coverage questions and self-pay financing options with you during the consultation, so you know your costs before you commit.
Neither is better for everyone. Bypass is often favored for patients with significant acid reflux or type 2 diabetes, while the sleeve is a simpler operation that suits many others. Dr. K performs both, so his recommendation is based on your health rather than on the one operation a surgeon offers.
Our patients typically return to work 4 to 7 days after their procedure. Lifting anything over 20 lbs is off limits during early healing, so jobs with heavy lifting may need more time.
Yes. An EGD and medical clearances are part of preparing for surgery. An endoscopy done within the last 5 months is accepted, and you can have it with Dr. Keshavarzi or at another facility.
