New research suggests that SARS-CoV-2–mediated vagus nerve dysfunction (VND) might be the source of some symptoms of long COVID, including dysphonia, dizziness, dysphagia, orthostatic hypotension, tachycardia, and diarrhea. In a cohort of 348 patients, 228 (66%) had at least one symptom that was suggestive of VND. The current evaluation was performed in the initial 22 patients with VND symptoms. The most frequent symptoms related to the vagus nerve were diarrhea (73%), tachycardia (59%), dizziness, dysphagia and dysphonia (45% each), and orthostatic hypotension (14%).
