Coronaviruses can cause more severe symptoms and complications in people with obesity-related conditions, according to the World Health Organisation (WHO). Data presented by the NHS up to 19 March 2020 showed that over three quarters (76.5%) of critically ill coronavirus patients admitted in critical care are overweight or obese.

For most adults, a BMI of 18.5 to 24.9 is in the healthy weight range; 25 to 29.9 means you are overweight; 30 to 39.9 means you are obese; 40 or above means you are severely obese. According to the NHS data, out of 196 patients in critical care, nearly 65% were either overweight, obese or severely obese.

Why the link between obesity and covid?
According to the WHO, coronoviruses can cause more severe symptoms and complications in people with obesity-related conditions. There appears to be consensus among experts that both coronary artery disease and heart failure patients are at increased risk of acute events or exacerbations from viral respiratory infection, with other comorbidities including diabetes, obesity, hypertension, kidney disease and COPD further increasing risk.
