Ever heard of using a pacemaker for weight loss, well vBloc is an up and coming procedure that is doing just that. Everywhere you look, there is someone struggling to lose weight. Sometimes it gets to the point that you want to give up and quit. Surgery is always risky, but using a less invasive surgical procedure lowers the risks and makes weight loss surgery safer. vBloc is considered the safest weight loss device there is. The best part about it is that you do not need any incisions to the stomach. Maybe vBloc has been the thing missing from your weight loss journey.


You may be wondering how and why a pacemaker-like device would be used to help you lose weight. A pacemaker works with the electrical signals of the nerves. What you may not realize is that there are nerves everywhere. You may think the body only functions off blood and oxygen, but when it comes down to it, without proper nerve communication, even those processes will not work right. The nerves help with digestion, but it also controls hunger. Being hungry is a result of the stomach communicating with the brain that it is empty. The first step is the production of specific hormones. Once those hormones are released, it triggers the nerves to respond sending signals to the brain. If there are malfunctions in the release of hormones or the way the nerves signal the brain, you may feel hungry even when you are not. vBloc helps to treat that.

How Does it Work?

The “V” in vBlock stands for vagus. The vagus nerve is the primary nerve that supplies the digestive tract and controls hunger. As stated earlier, when you are hungry, the nerve sends a message to the brain letting you know that it is time to eat. vBloc regulates communication between the stomach and the brain. The device blocks the signal from the vagus nerve to the brain. It is not a constant thing, but an intermittent thing. If it blocked every signal, you would end up not eating at all, which may seem like the answer to your weight gain, but that can be dangerous. Just like a pacemaker, the Maestro System Device can be adjusted. The strength and repetition of signals being released are adjusted to each patient needs. They can be increased or decreased as needed.  After surgery, most people feel changes instantly.

vBloc Procedure

The surgery is performed in a hospital under general anesthesia. The procedure can last anywhere from 60-90 minutes. To start the procedure, incisions are made in the abdomen. There are three to five total incisions, and they are small. The pacemaker type device is known as a Maestro System Device. The device is placed near the ribcage. The electrodes connected to the wire are placed on the vagus nerve of the stomach. The procedure is minimally invasive; therefore scarring is minimal and recovery quick. You may only be down a few days, and then you can return to work.

vBLoc Risks

The risks of vBLoc are minimal compared to the risks of other weight loss surgery methods. The small incisions make the surgery minimally invasive; this lowers the risk of infection. Risks do include device malfunction and pain at the site of the device and incision. Other risks include disease of the gallbladder, lung collapse, and vomiting. These things are not common but something you should be aware of after the procedure.


The good thing about the procedure is that it can be reversed. With a lot of weight loss procedures, once it is done it is done. The procedure cannot be reversed, and whatever side effects you have, you have to deal with. Along with other surgeries not being reversed, you also suffer from serious health risks. When parts of the intestines or stomach are removed, you lose the ability to absorb certain nutrients. You begin to lack nutrients and vitamins in the blood. vBloc also helps with high cholesterol, high blood pressure, and glucose levels. This procedure cuts down on having to go to the doctor all the time for check-ups. Once the device is set to the right level, you should be okay to start your daily activities.

Candidates of vBloc

Everyone is not a candidate for the procedure, but if you meet certain criteria, then your physician may consider you for the procedure. You have to be at least 18 years of age to undergo the procedure.You also have had to try other weight loss methods, primarily diet, and exercise, that has not been effective. If your BMI is between 35 and 40, you will be able to have the procedure safely. If your BMI is higher than that and your are dealing with other health issues like diabetes and high blood pressure, you may also be a candidate.

vBloc is becoming a great method of treatment for obesity. If you have tried everything and nothing seems to work, this may be the procedure for you. Talk with a physician about it right away. You no longer have to struggle with your weight.
