Helping you take control of your health
We know that losing weight can be difficult, but maintaining a healthy weight is crucial to avoiding many serious health problems. That's why our multidisciplinary bariatric team is here to offer the comprehensive care you need before during and after your procedure.


If you've been diagnosed as overweight or obese, it's important to return to a healthy weight. So if you're ready to take back your health, we're here to help.

We understand that losing weight can be a difficult process. But it's important to know that excess weight can cause serious health problems like diabetes, high blood pressure and heart disease, and in extreme cases, can affect your quality of life and your ability to perform activities you love. 

For some, bariatric surgery is an effective way to achieve weight loss. In fact, 90 percent of people who have bariatric surgery lose at least 50 percent of their excess body weight. Bariatric surgery works by limiting the stomach’s capacity to reduce hunger and help you eat less, and there are multiple types of weight loss procedures that accomplish this in different ways. One way is by restricting the amount of food the stomach can hold, while another is by reducing the absorption of food into the body. Some bariatric surgeries use both methods.

At Staten Island University Hospital, our bariatric surgery specialists are here to guide you through your weight loss journey every step of the way. 

Our program

The team at our Center for the Surgical Treatment of Obesity has been performing bariatric surgery for close to 20 years. We use a comprehensive, multidisciplinary approach that looks at all aspects of patient health and well-being before, during and after surgery. With more than 2,400 completed cases to date, our proven formula has achieved safety and success rates that meet or exceed the national norms.

Our team includes specialists in:

  • Nutrition
  • Surgery
  • Psychiatry
  • Internal and pulmonary medicine
  • Cardiology
  • Anesthesia
  • Rehabilitation
  • Social work

As part of your care, we also provide special services to meet your particular needs, such as:

  • Equipment to accommodate larger patients, providing a greater sense of comfort and safety
  • An expert nursing unit trained in treating bariatric surgery patients 
  • A nurse practitioner and a nutritionist on call to answer questions regarding diet and pre- and postoperative issues
  • Lifelong follow-up including diet and exercise counseling, behavioral counseling and support groups

Types of surgeries

We offer three different surgical weight loss procedures:

  • Gastric bypass
  • Sleeve gastrectomy
  • Lap-Band

Though each is associated with different weight loss outcomes, all provide significant results within 12 to 24 months following the procedure. Most times, this weight loss is sustained over the long term.
