STUDY: Weight gain after smoking cessation linked with increased short-term diabetes risk

People who gain weight after they quit smoking may face a temporary increase in the risk of developing type 2 diabetes, with the risk directly proportional to the weight gain, according to a new study from Harvard T.H. Chan School of Public Health. But regardless of weight gain, quitters can reap significant health benefits, including lower risk of cardiovascular disease, cancer, and early death.
