Adults from China who reversed their prediabetes to normal blood glucose had a 38% reduced heart attack risk and a 28% reduced ischemic stroke risk after about nine years of follow-up, compared with those whose prediabetes progressed to diabetes. The findings in the Journal of the American Heart Association also showed that all-cause mortality risk decreased by 18% among those who reversed their prediabetes to normal blood glucose, compared with those who progressed to diabetes.
