Bariatric surgery

Bariatric surgery is designed to help people lose and keep off large amounts of weight to alleviate health issues and improve quality of life.

Being severely overweight places us at risk for heart disease, hypertension, diabetes, arthritis, sleep apnea, cancer, and depression. It can also rob us of much of the joy in life that we all deserve. If attempts at serious weight reduction have failed, you may be a candidate for bariatric surgery, and Community Hospital's Bariatric Surgery Center is here to help.

Learn More About Our Program

Community Hospital of the Monterey Peninsula was one of the earliest in the country to be designated a Bariatric Surgical Center of Excellence by the American Society of Metabolic and Bariatric Surgery.

In 2012, the American College of Surgeons and the American Society for Metabolic and Bariatric Surgery combined their respective accreditation programs in a single program to achieve one national standard. That accreditation, now held by Community Hospital, is the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP).

We take great pride in a program that is able to offer not only state-of-the-art, safe surgery, but comprehensive nutritional counseling and psychological support as well. Our program started in 2001 and our surgeons have performed more than 1,900 weight loss operations. The most commonly performed bariatric operations at Community Hospital are:

  • laparoscopic gastric bypass
  • sleeve gastrectomy
  • laparoscopic gastric band (lap band)

We also perform laparoscopic and open revisional weight loss surgery when necessary and we have a special interest and expertise in caring for seriously overweight people who need non-weight loss surgery, as well.

Perhaps most importantly, we have a comprehensive program that includes dietitians, psychologists and psychiatrists, physical therapists, and a robust complement of support groups that enable us to care for all of the needs of individuals undergoing weight loss operations.

The program is directed by Mark Vierra, MD, who has performed bariatric surgery since 1991, when he established the bariatric surgery program at Stanford University Medical Center. In 2001, he moved his practice to Monterey, and now has performed more than 3,350 bariatric procedures.

Before surgery: Introductory lecture

Bariatric surgery at Community Hospital begins with a free informational meeting held monthly for anyone interested in bariatric surgery. Prospective patients then:

  • Are evaluated individually by a surgeon
  • Receive dietary and psychological counseling
  • Undergo medical testing to assess overall health and fitness for surgery

Prospective patients are also encouraged to attend a support group meeting before surgery to hear firsthand from people who have undergone bariatric surgery.

Receiving services at an Optum Bariatric Resource Services (BRS) Center of Excellence (COE) facility can help ensure that bariatric surgery and care are delivered in a manner that meets strict standards and increases the likelihood of superior outcomes and ultimately reduces costs.
