What’s more, the statins seemed to make people more resistant to the effects of insulin—which breaks down sugar—and to secrete less insulin. The impact on insulin seemed to be greatest among those who started out with the lowest, and closest to normal, levels of blood glucose. And the higher the dose of the statin, and the longer the patients took them, the greater their risk of diabetes.

Previous studies have suggested that statins can raise blood sugar levels, and increase the risk of diabetes by anywhere from 10% to 20%, but none have documented an effect this large. Doctors often consider statins for patients who are at higher risk of heart disease, and one of the risk factors fo...
