Here’s another reason to watch your waistline. A new study finds that people who carry too much weight around the middle may be putting a burden on their lungs.
Researchers reviewed the health of 120,000 people in France and found that those who were too thick around the abdomen had worse lung function.
The researchers, writing in The American Journal of Respiratory and Critical Care Medicine, defined abdominal obesity as a waistline of 35 inches or more for women and 40 inches or more for men.
They have several explanations for why this might make the lungs work less well.
It may simply be that the added fat gives the lungs less room to expand. But it may also be that the fat cells act to increase inflammation throughout the body, including in the lungs.
Whatever the reason, impaired lung function can be a signal of serious health problems in the future.
