Heart disease risk may be increased with air pollution exposure.

The risk of heart disease may be higher with greater exposure to air pollution, especially for people with diabetes.
Experts found that air pollution exposure can increase blood sugar, cholesterol levels, and other factors that may raise heart disease risk.
Obesity, poor diet, lack of physical activity, high blood pressure, high cholesterol, and diabetes are among the numerous factors known to increase the risk of heart disease.
"While air pollution is linked with relatively small changes in cardiometabolic risk factors, the continuous nature of exposure and the number of people affected gives us cause for concern. Even small changes in glucose levels and glycemic control can contribute to increased risk of cardiovascular disease."
