Scientists at the Germans Trias i Pujol University Hospital in Catalonia have discovered that vagus nerve dysfunction plays a central role in the development of the long-term COVID syndrome. Research results published The Lancet is considered a preprint until it is published on the preprint server and in a peer-reviewed journal.
The scientists compared the structure and function of the vagus nerve in patients with and without long-term COVID. The vagus nerve plays a role in the functioning of the pharynx, larynx, heart, lungs and gastrointestinal tract.
People with long-term covid had more vagus nerve-related symptoms. The scientists found changes associated with disruption of the vagus nerve and found that in 60% of patients, the diaphragm, a domed structure that plays a crucial role in breathing, becomes flattened. This may explain why some people experience shortness of breath despite the absence of pathology in the lungs.
The results of the study point to the critical role of vagal dysfunction in development. Scientists’ data could improve diagnosis and treatment of long-term COVID. Future research should explore whether vagus nerve ultrasound can produce different outcomes in patients with long-term COVID in the early and late stages of the disease.
Long-term COVID-19 affects at least 5-10% of people who survive acute SARS-CoV-2 infection. All study participants had at least one long-term COVID-related symptom, such as voice or swallowing problems, shortness of breath, tachycardia, cough, orthostatic hypotension (excessive drop in blood pressure when standing up), gastrointestinal disturbances, dizziness. problems with mental functions.
