Cigarette smoking increases your risk of type 2 diabetes, in addition to harming your heart and lungs. Current smokers can have a 45 percent increased risk of developing diabetes, according to a recent meta-analysis.1 Smoking impairs the way the body reacts to insulin. At normal BMI, smokers are more likely to have central obesity than non-smokers. In many Asian countries, more than half of adult men are regular smokers.2 China and India are the greatest producers and consumers of cigarettes in the world. If you quit smoking now, you’ll significantly reduce your risk of developing diabetes and other diseases over the long term.1
