Vagus nerve compression disrupts its "rest and digest" signals, leading to wide-ranging issues like digestive problems (bloating, nausea, gastroparesis), heart issues (irregular rate, blood pressure changes, dizziness), breathing difficulties, chronic pain, anxiety, and mood disturbances, as it impairs communication between the brain and organs, causing sympathetic "fight or flight" dominance and inflammation.

Here are some things that you can do to strengthen your vagus nerve:
Irritation of these nerves can therefore lead to such horrific stabbing or lightning-like pharyngeal pain that it can make it hard to swallow and is associated with nausea and vomiting. The condition is called is vago-glossopharyngeal neuralgia.
Scar tissue built up around vagus nerve may cause nerve irritation. Subsequently, nausea, vomiting, sweating and diarrhea may develop. It is also possible that your vagus nerve was partially injured during surgery. Vagus injury has been reported to cause diarrhea immediately after surgery.
The vagus nerve, a key component of the cross-communication between the gut and the brain, is a major element of homeostasis sensing the “milieu intérieur” and boosting the nervous and endocrine responses to maintain the gastrointestinal health status.
There are two main causes of vagus nerve dysfunction: previous infection or inflammation and physical or psychological stress.
You'll meet with your neurologist who will program the VNS device to deliver electric impulses in regular intervals to your brain. For example, your neurologist may set the device to send electric impulses to your vagus nerve for 30 seconds on and off for five minutes.
There's no single “best” position to stimulate your vagus nerve; instead, focus on maintaining spinal alignment (like sleeping on your back with a supportive pillow) for better sleep quality.
High-resolution MRI identifies vagus nerve conflicts, but imaging findings must match clinical symptoms.
It plays a vital role in regulating numerous bodily functions, including heart rate, digestion, and immune response. While the vagus nerve's primary course is through the neck, it is not immune to the impact of cervical instability a condition that can lead to compression or irritation of the nerve.
Your vagus nerve's state directly affects both digestion and vision. Poor vagal tone can lead to: Reduced nutrient absorption affecting eye health. Decreased tear quality due to inflammatory responses.
Gargling engages the muscles connected to the vagus nerve and can help tone it over time. Try gargling warm water for 30 seconds a few times a day when you have a free moment to yourself. Some people even use this as a micro-break between meetings or tasks to reset their stress baseline.
Damage to the vagus nerve is usually caused by trauma, surgery, or disease. In some cases, it may be possible to repair the damage. However, in other cases, the damage may be permanent.
Cardiovascular health: The vagus nerve helps to regulate heart rate and blood pressure. High vagal tone is associated with a lower resting heart rate, reduced blood pressure, and increased heart rate variability (HRV), which is the variation in time between heartbeats.
Or you can simply focus on your breathing and quiet surroundings. Gentle exercise, such as yoga, stretching, or any kind of slow, relaxed movement can also restore balance. It helps reset your heart and breathing patterns. Strength training or any exercise that gets you moving will affect the vagus nerve.
The unhealthiest sleeping position is generally considered to be sleeping on your stomach (prone position), as it forces your neck to twist and flattens the natural curve of your spine, leading to neck, back, and shoulder pain, numbness, and poor sleep quality. An overly curled fetal position is also harmful, causing joint stiffness and restricted breathing, while sleeping on your back can worsen snoring and sleep apnea for some individuals.
Do
The 3-2-1 sleep rule is a simple wind-down routine: stop eating and drinking alcohol 3 hours before bed, stop working/mentally stimulating activities 2 hours before, and turn off screens (phones, TVs) 1 hour before sleep, helping you transition to rest by reducing stimulants and preparing your mind and body. It's often part of a larger 10-3-2-1-0 rule, which also adds no caffeine 10 hours prior and no hitting snooze (0) in the morning.
BCBSNC will provide coverage for Vagus Nerve Stimulation for Treatment of Seizures when it is determined to be medically necessary because the medical criteria and guidelines shown below are met. Vagus Nerve Stimulation for the treatment of essential tremor and other conditions is considered investigational.
Six reasons you should see a neurologist
Signs of Vagus Nerve Dysfunction
Common symptoms include chronic neck and shoulder pain, unexplained dizziness, digestive problems, anxiety, difficulty swallowing, voice changes, and persistent fatigue. Many people also experience heart palpitations, blood pressure fluctuations, and heightened sensitivity to stress.
While no specific vitamin can “cure” the vagus nerve, maintaining adequate levels of vitamins B12 and D is essential for full vagus nerve activity and health. These vitamins support the nervous system and overall well-being.
Several chiropractic treatments can improve the health of the vagus nerve. Adjustments help to keep the nerve functioning properly, while massage can help to stimulate it and enhance communication between the brain and the body. Exercises that work on the core muscles can also help to improve vagus nerve health.
