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 this spring.
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.
