Pressure On Vagus Nerve Symptoms
Vagus: Damage to the vagus is unlikely to cause pain or high bp. ...Read more
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
Yes.: Overactive example pass out when see blood. Sympathetic failure? Trigger points localized points discomfort with bizarre symptoms if activated are sympathetically maintained. There is sympathetic sudomotor syndrome where compress area lets say neck muscle and only 1/2 forehead sweats. Simple injury to sympathetics can produce severest of pains that may destroy persons life called regionalpreviousn. ...Read more
Nerves in the neck: The vagal nerves, 1 on either side of the neck, control the vocal cords; the left vagal nerve also gives parasympathetic innervation to the heart. In theory, gerd shouldn't stimulate the vagal nerves, because the esophagus is further back in the throat, while the vagal nerves are close to the front of the throat. ...Read more
My uvula is deviated to the left, could this be serious? Could I have a tumor impinging my vagus nerve? I don't have any other symptoms.
You're fine: I see that you are a first year medical student. Deviation of the uvula is a marker for a cranial nerve palsy, but when you eventually see it in real life, it's spectacular and the movements of the other throat muscles are obviously abnormal. Few uvulas are truly straight. You'll also learn that you have palpable lymph nodes in your neck that may not be in the anatomy book -- they're okay too. ...Read more
UNUSUAL: Lesions in the lower brainstem, medulla oblongata are rather rare, but if they do occur, one might encounter problems with speech, such as a dysphonia, or a strained speech pattern. If there is widespread inflammation, also involving glossopharyngeal nerve, might see dysphagia, or swallowing problems. Likely the internal organs such as heart, lungs, GI tract would not be involved. ...Read more
How random can food allergy reaction be? Recently told have allergy to some nuts. Hives once. History of vagus nerve symptoms resuming in minutes on own
Depends: Incidence of nut allergy is around 1%. People with atopic dermatitis are more likely to develop food allergy via skin contact. Remember that a positive skin or blood test does not prove food allergy- just a potential. You must have symptoms from eating the food. People allergic to one nut is more likely allergic to another but they are not related. See an allergist. ...Read more
Does gerd/acid reflux always cause stimulation of the vagus nerve? If yes, are symptoms of stimulation different from those of anxiety?
Interesting question. Symptoms of stimulation of the vagus nerve are not usually associated with anxiety. The vagus nerve has many functions and I won't go into all of them here do to space limitations.
Reflux can cause stimulation of the nerve and chest pain and synocope/near synocpe (passing out) can happen but that's often in severe cases and usually with cold/hot beverages/drinks. ...Read more
What would the Symptoms of vagus nerve damage be like due to MS? Also where would they be found on an MRI? Would the lesions be in the c spine?
Alter body functions: Controlled (heart, lungs, digestive tract & other organs within chest & abdomen) by 2-way communication via the vagus nerve, the 10th of the cranial (ones which do not go through the spinal cord, thus not within the spinal cord; C-spine vertebra) nerves. Research vagus anatomy&physiology on Google. MRI best for soft tissue yet reveals very little of the fantastic complexity within what is imaged. ...Read more
Developed reflux symptoms after Cholecystectomy. Could the LES become weaken/stop working due to a disturbed vagus nerve after Gallbladder removal?
Vagotomy # effects: Vagotomy (cutting of the vagus nerve) is a now-obsolete therapy that was performed for peptic ulcer disease. Vagotomy is currently being researched as a less invasive alternative weight-loss procedure to gastric bypass surgery. the procedure curbs the feeling of hunger and is sometimes performed in conjunction with putting bands on patients' stomachs, resulting in average weight loss of 43% at. ...Read more
Seizure treatment: Vns is an fda-approved treatment for patients with refractory partial epilepsy (over age 12). It is a matchbook-sized device implanted under the skin in the upper left chest with a wire that connects to the left vagus nerve (in the neck). It is programmed by your neurologist to provide electrical stimulation for 30 seconds at 5 minute intervals. It can be a very effective treatment. ...Read more
Not a MOA: Hydralazine is a direct smooth muscle relaxer based on its intracellular action on Calcium. In situ, it does not appear to have a direct effect on the vagus nerve, but rather may have an effect on the sinoatrial node and a reflex response (increased heart rate) due to the decreased blood pressure (baroreceptor response). ...Read more
Hydralazine: It relaxes vascular smooth muscles, resulting in dilation of arteries & arterioles (small vessels). ...Read more
Please clarify: Frankly, I have no idea what your post means. The vagus nerve is PART of the nervous system. It's part of the parasympathetic nervous system. Maybe if you posted what led you to ask the question I could figure out what you mean because right now I haven't got a clue. It's like asking, "Which part of the car is control by 75% of the windshield? " ...Read more
Why do you ask?: Where did you get idea that your vagus nerve is damaged? Vagal input on the right affects the heart rate, and on left predominantly, the other internal organs within the thorax and abdomen. Vagal function can be tested, but I have NO clue as to why you are asking your question. ...Read more
Vagal Disorders vary: Neuralgia, respiratory and vocal problems, problems swallowing, stomach problems [gastroparesis], vasovagal reflex induced fainting, heart arrhythmias, and urinary problems. Patients with anxiety, depression, or who lose consciousness during complex partial seizures or generalized seizures, and whose seizures are not being controlled by medication, may benefit from vagal nerve stimulation. ...Read more
Never heard that BUT: I don't see why a Vagus Nerve couldn't be inflamed by autoimmune circumstances, the presence of a virus, or being caught up in nasty abscess. So by that standard any organ including the heart could be affected if the actual vagal connections are compromised due to inflammation of the nerve. I think it would be very hard to prove Vagal Neuritis with today's science but we could figure it out. ...Read more
A bright 20yr old with 8autoimmune dx, 2 syndromes.11dr. Over 2yrs countless test, restricted diet, etc. She is having short lock in episodes. Vagus nerve?
Too complex: Too little information, can't give you a meaningful response. ...Read more
Uncontrolled sz: Those with uncontrolled partial epilepsy should be evaluated for resective epilepsy. If not a candidate, those with uncontrolled seizures may consider vagus nerve stimulation (vns). Vns should be thought of as another anti seizure medication (aed). It rarely eliminates the need to take aeds. It is palliative, not curative. ...Read more
