Quitting Smoking Improves Health Despite Temporary Type 2 Risk
People who gain weight after they quit smoking are temporarily at greater risk for developing type 2 diabetes than if they hadn’t quit, but their risk for early death still drops. Among more than 170,000 adults from three studies who researchers followed for nearly 20 years, the risk of developing type 2 diabetes rose by about 22 percent within five to seven years of giving up cigarettes, but remained stable after that. The risk was seen only among people who gained weight after quitting. But the benefits of quitting still outweighed the risks: Even among participants who put on more than 22 pounds after they quit, the risk of death from heart disease was cut in half and the risk of death from any cause dropped by two-thirds.
