COVID-19 and obesity: Doctors are studying link between excess weight and severe disease.
In the United States, the obesity rate among adults has climbed for decades and is now at 42 percent. The rate is even higher among Black and Hispanic Americans.
. Carrying around a lot of extra weight strains the body, and that excess fat could limit the lungs' ability to expand and breathe.is a natural way our bodies fight harmful intruders like viruses. But long-lasting inflammation isn’t healthy and could undermine your body’s defenses when a real threat arises.
How fat is distributed in the body may play a role too. One study found an increased risk for death from COVID-19 for people with severe obesity, but only among men. The findings could reflect that men tend to carry fat around the stomach, said Sara Tartof, a co-author of the study who researches infectious diseases at Kaiser Permanente in Southern California. That type of fat is more associated with the production of a hormone that could be contributing to more severe illness, she said.
“They need a machine to help just do the work,” said Dr. David Kass of Baltimore's Johns Hopkins University, who has co-authored a study on obesity and severe COVID-19 illness.
