The left vagal nerve runs down the left side of your neck, and the right vagal nerve runs down your right side. This nerve extends all the way from your brain to the large intestines: down your neck, through your chest, around your heart, around your lungs, and through your abdomen and intestines.
Your vagus nerve is connected to your vocal cords, the muscles at the back of your throat and passes through your inner ear. Try humming or singing or just listening to calm, soothing music. Those sounds and vibrations may stimulate your vagus nerve.
When the vagus nerve itself gets damaged, you'll obviously deal with some pain in your neck - but other weird symptoms will present themselves as well. You'll notice issues with your voice, problems with your throat, an increased heart rate, brain fog, excessively high or low blood pressure, and gut problems.
This vagal nerve damage can result from diabetes, viral infections, abdominal surgery and scleroderma. Vasovagal syncope: Syncope is another word for fainting. Vasovagal syncope occurs when a vagus nerve to your heart overreacts to certain situations like extreme heat, anxiety, hunger, pain or stress.
There are two main causes of vagus nerve dysfunction: previous infection or inflammation and physical or psychological stress.
What Triggers the Vagal Response? The vagal response (vasovagal reflex) is when stimulation of the vagus nerve causes symptoms such as lightheadedness, sweating, and blurred vision. This can happen because of stress, pain, heat, having a bowel movement, or even standing too long.
Based on research results and clinical experience, cervical region tightness can be considered to cause stomach problems through the vagal nerve, and soft tissue relaxation of the cervical region can be a promising treatment method for stomach symptoms.
Conclusions: Right lateral decubitus position leads to the highest vagal modulation in the controls, whereas the supine position leads to the lowest vagal modulation in the CAD patients.
At UCSF Health, our neurologists and neurosurgeons have expertise in implanting vagal nerve stimulators to treat seizures caused by diseases such as epilepsy.
“The mammalian vagus nerve regenerates poorly after injury, which can result in loss of speech, difficulty swallowing, abnormal heart rate, and gastroparesis [improper stomach emptying],” the authors explain. In zebrafish, on the other hand, nerve regeneration is generally very successful.
CT scan or MRI cannot show the vagus nerve.
Low vagal tone has been associated with chronic inflammation. Research shows that those with inflammatory conditions, such as rheumatoid arthritis and other autoimmune diseases, often have decreased heart rate variability, a marker of reduced vagal tone.
The vagus nerve is the body's superpower and it's used to counteract your fight/flight system. It's how you develop a healthy stress response and become resilient. When stimulated, you feel calmer, more compassionate, and clearer. Stimulating the vagus benefits your autonomic nervous system and mental health.
“You can do things like yoga and deep breathing exercises. Those indirectly stimulate the vagus nerve by stimulating other organs the vagus nerve innervates,” says Howell. “Another interesting one is loud gargling with water or singing, both of which stimulate the vocal cords, which then stimulate the vagus nerve.
Any kind of GI distress can put pressure on the Vagus nerve and irritate it resulting in further problems. An excess of alcohol, spicy foods, and caffeine can inflame the nerve. As we now know, our gut is considered to be our “second brain”, also known as our enteric nervous system.
The most important function of the vagus nerve is afferent, bringing information of the inner organs, such as gut, liver, heart, and lungs to the brain. This suggests that the inner organs are major sources of sensory information to the brain.
Any form of moderate massage to the neck and shoulders can help improve the functioning of your vagus nerve. A painful form of massage may not be a great choice because muscle pain may trigger the sympathetic nervous system, causing a “fight or flight” response.
However, chronic stress can impact the vagus nerve in a negative way. 2 This can lead to problems such as anxiety and depression. It can also make the body more susceptible to infections and diseases. 3 Therefore, it is important to manage stress in order to maintain a healthy vagus nerve.
