If you’re a smoker, you sustain a 65 percent higher risk of developing glucose intolerance than nonsmokers. Previous research has already linked smoking with diabetes. However, a new study of over 4,500 people in four U.S. cities shows passive smoking (secondhand smoke) may also elevate your blood sugar (glucose) levels.
Individuals exposed to secondhand smoke over a 15-year period carry a 35 percent elevated risk of glucose intolerance. This condition is also called pre-diabetes because it’s often a precursor to type 2 diabetes.
