Body weight makes a significant contribution to health: a weight that is too high or too low, for example, harbors risks in the cardiovascular area. Weight therefore also plays a central role when infected with Sars-CoV-2, as a publication by the Centers for Disease Control and Prevention in the “Morbidity and Mortality Weekly Report” shows.
Overweight has long been considered a risk factor for severe Covid courses: Chronic inflammatory reactions in visceral obesity play just as much a role as lung function disorders due to increased adipose tissue. The CDC Covid-19 Response Team had the data of 3.2 million hospital patients available for their investigation, almost 150,000 were treated for Covid-19.
Being underweight can also be dangerous
The study shows that people with a body mass index (BMI) of 18.5 or lower also have an increased risk of a severe course of Covid. Such a BMI is considered to be underweight – the risk of hospitalization was increased by 20 percent, and by 41 percent for those under 65. However, it was not possible to determine an increased risk for necessary intensive treatment; the same applies to mechanical ventilation or the risk of death.
