It is typical for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to affect the gastrointestinal tract, which may manifest as an early warning sign. The frequency of gastrointestinal symptoms often indicates the seriousness of coronavirus disease 2019 (COVID-19). COVID-19 may impair the nerve supply to the digestive system, resulting in autonomic dysfunction of the gastrointestinal tract. There is still much to discover about the impact of COVID-19 on the autonomic nervous system and the gastrointestinal tract.
Due to the importance of gastrointestinal tract autonomic dysfunction in patients with COVID-19, we are motivated to conduct this systematic review concerning this newly emerged condition that has become a concern during the pandemic.
Our objective is to thoroughly investigate the epidemiology, clinical manifestations, potential mechanisms, diagnosis, differential diagnosis, and impact of gastrointestinal autonomic dysfunctions on the quality of life and prognosis of individuals who have contracted SARS-CoV-2. Additionally, we will explore management and prevention strategies.
We conducted a comprehensive and systematic exploration of multiple databases, followed by an extensive analysis of the relevant literature. Our review included 113 studies published in English between January 2000 and April 18, 2023.
According to most of the literature, gastrointestinal autonomic dysfunction can greatly impact a patient's quality of life and prognosis. Many factors can affect the functioning of the gastrointestinal autonomic nervous system. Studies have shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a documented affinity for both neural and gastrointestinal tissues, which can lead to various gastrointestinal symptoms. These symptoms include anorexia, dysgeusia, heartburn, belching, chest pain, regurgitation, vomiting, epigastric burn, diarrhea, abdominal pain, bloating, irregular bowel movements, and constipation. Diarrhea is the most common symptom, followed by anorexia, nausea, vomiting, and abdominal pain. While COVID-19 vaccination may rarely cause autonomic dysfunction and gastro
To achieve optimal results for individuals with COVID-19, it is crucial to adopt a multidisciplinary approach, which includes providing supportive care, treating the underlying infection, managing any dysfunction, monitoring for complications, and offering nutritional assistance. It is imperative to closely monitor the patient's condition and take swift action if necessary. Additionally, conducting comprehensive research on the gastrointestinal autonomic dysfunction caused by COVID-19 is critical for effective management.
A multi-faceted approach is essential to ensure the best outcome for those affected by coronavirus disease 2019 (COVID-19). This includes providing supportive care, addressing the root infection, managing dysfunctions, monitoring for complications, and providing nutritional aid. It is crucial to closely monitor the patient's condition and take prompt action if needed. Furthermore, in-depth research on COVID-19-induced gastrointestinal autonomic dysfunction is vital for proper management.
