A study has found that the fatality rate is higher in obese patients with the novel coronavirus infection (COVID-19). According to a report by the South China Morning Post (SCMP) on the 2nd, a joint research team from the University of Edinburgh, University of Liverpool, and Imperial College London (ICL) conducted this study on 17,000 COVID-19 patients across 166 hospitals in the UK and published the results on the medical preprint site MedRxiv.



According to the paper, elderly COVID-19 patients had a higher fatality rate than younger patients. Additionally, the fatality rate was higher in males than in females. The research team analyzed, for the first time, the correlation between obesity and fatality rate. The results showed that obese COVID-19 patients had a higher fatality rate compared to non-obese patients. The team explained, "Obese individuals have poorer lung function than non-obese individuals, and excessive immune responses may occur due to subcutaneous fat or visceral fat." When the immune response is excessive, a 'cytokine storm' can occur, where the body's immune system attacks even normal cells.
