A Doctors Story

What is the Vagus Nerve?

The vagus nerve is the longest cranial nerve in the body, with branching nerves that go to the heart, lungs, stomach, and many other organs. It primarily serves as a sensory nerve, responsible for reporting information to the brain and transmitting instructions back to the body.

Think of the vagus nerve as the nervous systems “super-highway”, sending important communication between your brain and many parts of the body and back. It facilitates and communicates with many different system’s, operating and influencing things like pain regulation, anxiety, fatigue, heart rate, digestive track activity, and lung function.

How does gammaCore stimulate the Vagus Nerve?

Unlike an implanted vagus nerve stimulator or other migraine and cluster headache treatments, gammaCore non-invasive vagus nerve stimulator (nVNS) activates the vagus nerve with gentle electrical stimulation through the skin via the neck. gammaCore works to prevent and relieve headache pain without pills, injections, and drug-like side effects.

How does Vagus Nerve Stimulation help those suffering from headache pain?

The vagus nerve plays an important role in regulating pain. When stimulating the vagus nerve, pain signals causing the attacks can be blocked, helping provide fast relief and preventing future attacks before they happen.

Experience more headache-free days without worrying about drug overuse or inconveniences associated with injectables, inhalers, and medications.
