Laparoscopic Vagal Blocking (VBLOC)

Controlling weight without traditional surgery

The VBLOC device is a new, FDA-approved, laparoscopically implanted weight loss tool designed to control appetite without medications or traditional bariatric surgery.


Currently, Scripps Clinic Center for Weight Management is the only medical center in San Diego offering VBLOC therapy.


The VBLOC device consists of two very small electrodes specifically designed to block transmission of the vagus nerves, which send information about hunger and fullness from our brain to our stomach. Blocking the transmission leads to decreased appetite and longer feelings of fullness. This therapy helps patients eat less and lose weight.


Vagal blocking therapy is approved for people with a body mass index (BMI) between 35 and 45 who have at least one obesity-related medical problem, such as diabetes, sleep apnea or high cholesterol. The operation is performed on an outpatient basis, with patients going home the same day.


A physician programs the VBLOC device to send electrical impulses according to each patient’s unique needs, and can increase or decrease the intensity over time as needed. Patients lose approximately 30 percent of their excess weight in the first year.
