Sleeve Gastrectomy in NYC

More than 40% of American adults live with obesity, and for many, diet and exercise alone are not enough to achieve lasting weight loss. If you have tried to lose weight without success and your health is suffering as a result, sleeve gastrectomy may be the solution that finally works.

This proven, minimally invasive procedure has helped thousands of patients shed excess weight and reclaim their health. At NYC Hernia, Dr. Brian Jacob brings world-class expertise and genuinely personalized care to every patient considering weight loss surgery in New York City.

What Is a Sleeve Gastrectomy?

A sleeve gastrectomy is a surgical weight loss procedure in which approximately 80% of the stomach is removed, leaving behind a small, sleeve-shaped pouch. This significantly reduces how much food you can eat at one time and lowers levels of ghrelin, the hormone responsible for hunger, which helps curb appetite over time.

Dr. Jacob performs the procedure using just 5 small “keyhole” incisions, making it a minimally invasive option with a relatively quick recovery.

Are You a Candidate for Sleeve Gastrectomy?

You may be a candidate for sleeve gastrectomy if you meet one of the following criteria related to morbid obesity and body mass index (BMI):

You have a BMI of 40 or greater with no other related health conditions
You have a BMI of 35 or greater along with conditions such as high blood pressure, sleep apnea, type 2 diabetes, or PCOS

Dr. Jacob performs sleeve gastrectomy on patients ages 15 to 75. Not sure about your BMI? You can calculate it using your height and weight at the NIH BMI calculator (opens in new tab).

What to Expect: The Surgery Process

Before your surgery, you will meet with Dr. Jacob twice: once for your initial office visit and once just before the procedure. If you plan to use insurance, you can begin the precertification process even before your first appointment by gathering three key documents required by most insurers:

A letter from your physician confirming morbid obesity for at least 6 months despite supervised diet and exercise attempts
A letter from a bariatric nutritionist who completes a pre- and post-operative nutrition evaluation
A letter from a therapist or social worker confirming your mental health stability for surgery

Once collected, you can fax these documents to Dr. Jacob’s office at 212-650-9981 or mail them to: Dr. Brian Jacob, 1010 5th Avenue, New York, NY 10028. Call (212) 879-6677 if you need a referral for a nutritionist or therapist.

Recovery and Results

One advantage of sleeve gastrectomy with Dr. Jacob is the remarkably short hospital stay. Nearly every patient is discharged within 18 to 24 hours of the procedure. The goal of surgery is to help you lose 50% of your initial excess weight, though long-term success depends on follow-up care, nutrition, and a consistent diet and exercise routine.

Up to 30% of patients may experience some weight regain after the first 3 to 4 years. Staying connected with your surgical team and nutritionist greatly improves your chances of sustained results.

Risks and Side Effects

Sleeve gastrectomy is a major surgical procedure and carries risks. These may include, but are not limited to:

Bleeding, infection, or a leak
Deep vein thrombosis
Reflux esophagitis or heartburn
Constipation, nausea, or hair loss
Cardiopulmonary risks or prolonged hospital stay

Dr. Jacob has one of the lowest complication rates at Mount Sinai Medical Center, where he performs the procedure. He will walk you through all short- and long-term risks during your consultation so you can make a fully informed decision.
