Gastric Pacemaker

The gastric pacemaker is a new weight loss device offered by The Weight Loss Surgery Center Of Los Angeles that uses electric pulses to control a patient’s appetite. The device is put in place laparoscopically by Dr. David Davtyan and it does not surgically alter your stomach or your intestines, making it fully reversible. While the surgery is minimally invasive, it does require general anesthesia. The device is able to be controlled externally, without surgery, allowing Dr. David Davtyan to adjust it to maximize your weight loss and minimize any side effects.

The device sends out electrical impulses that block signals of hunger sent from your brain to your stomach. This reduces your appetite and makes you feel full quicker after eating. Because you are less hungry, you consume less calories, which is a health and safe way to lose weight.


  • If you are 18 or over.

The most serious side effects are nausea, pain at the site of the device, vomiting, heartburn, problems with swallowing, belching and chest pain. As with any surgery, there are always risks of other complications.
