[Obesity and hypertriglyceridemia: high risks for disease severity and mortality in COVID-19 patients]

As COVID-19 pandemic approaching its third year, more data have shown that obesity and hypertriglyceridemia are the high-risk factors for the major complications such as acute respiratory distress syndrome, thromboembolism, coagulopathy and cytokine storm, which are responsible for the majority of disease severity and mortality. In this review article, we have analyzed the public available clinical reports and laboratory research results of the COVID-19 studies by researchers and clinicians of many nations around the world. Many of these reports covered COVID-19 patients of different ethnic groups. We suggested that obesity and high triglycerides are high risks for severe COVID-19 and death. We also summarized the possible underlying molecular mechanism likely connecting the severe COVID-19 with obesity and hypertriglyceridemia. From public health perspective, we highlight the importance of the healthy diet and lifestyle in fighting against SARS-CoV-2 virus in long period of time.
