Long COVID Symptoms Linked to Effects on Vagus Nerve!
Several long COVID symptoms could be linked to the effects of the coronavirus on a vital central nerve, according to new research being released. The vagus nerve, which runs from the brain into the body, connects to the heart, lungs, intestines, and several muscles involved with swallowing. It plays a role in several body functions that control heart rate, speech, the gag reflex, sweating, and digestion. Those with long COVID and vagus nerve problems could face long-term issues with their voice, a hard time swallowing, dizziness, a high heart rate, low blood pressure, and diarrhea, the study authors found.
@debraj Most long COVID subjects with vagus nerve dysfunction symptoms had a range of significant, clinically-relevant, structural and/or functional alterations in their vagus nerve, including nerve thickening, trouble swallowing, and symptoms of impaired breathing. The study appears to add to a growing collection of data suggesting at least some of the symptoms of long COVID is mediated through a direct impact on the nervous system. Establishing vagal nerve damage is useful information, as there are recognized, albeit not perfect, treatments for other causes of vagal nerve dysfunction that may be extrapolated to be beneficial for people with this type of long COVID.
