Obesity Linked to COVID-19 Severity......

Obesity and Covid

It is becoming increasingly clear that obesity is one of the biggest risk factors for severe COVID-19 disease, particularly among younger patients. Recently published data from New York show that among those under 60, obesity was twice as likely to result in hospitalization for COVID-19 and also significantly increased the likelihood that a person would end up in intensive care.

Obesity and severe obesity were significantly more prevalent among the patients with COVID-19, at 47.6% and 28.2%, versus 25.2% and 10.8% among historical controls (P < .001 for trend). A key finding was that those with a BMI > 35 kg/m2 had a more than the sevenfold increased risk of requiring mechanical ventilation (odds ratio [OR], 7.36; P = .021), compared to those with a BMI < 25 kg/m2, even after adjusting for age, diabetes, and hypertension.

The culprit behind the increased risk of disease severity seen with obesity in COVID-19 is inflammation, mediated by fibrin deposits in the circulation, which "block oxygen passage through the blood, thus aggravating Severe acute respiratory syndrome.

"Patients with obesity should avoid any COVID-19 contamination by enforcing all prevention measures during the current pandemic,"
