Smoking Raises Risk of Diabetes

Smoking is linked to a significantly increased risk of developing type 2 diabetes, US research suggests.The University of Lausanne looked at 25 studies involving 1.2 million patients. They found smokers had a 44% increased risk of type 2 diabetes compared with non-smokers - with the risk rising with the number of cigarettes smoked. The Journal of the American Medical Association study found the increased risk for those who smoked at least 20 cigarettes a day rose to 61%. For lighter smokers the risk was 29% higher than for a non-smoker. The increased risk of developing diabetes in former smokers was 23%
