Gut Microbiota, NAFLD and COVID-19: A Possible Interaction

Abstract

COVID-19, which is caused by SARS-CoV-2, is a major public health concern around the world. The beta coronavirus family includes SARS-CoV2, which enters cells via the ACE2 receptor. Patients in Wuhan, China, who suffered from the first sickness had no symptoms concerning the digestive system. Only 2.6% developed diarrhea, and only 2% had chronic liver illness. As the situation becomes more complicated, more people are reporting gastric issues. The disorder is characterized by diarrhea, anorexia, nausea, vomiting, abdominal discomfort and gastrointestinal bleeding, with diarrhea being the most common symptom. Several theories have been proposed for the genesis of gastrointestinal issues. Virus-induced cytopathic effects via ACE2, immune-mediated inflammatory cytokine storm, gut–lung axis function and drug-related damage are among them, not only in cases of COVID-19, but also in gastrointestinal illnesses.
