Even in older age, prediabetes can often be controlled or reversed, according to hopeful results from the Karolinska Institute in Stockholm. More than 900 seniors with the condition were followed for up to 12 years. During this time, only 13 percent progressed to diabetes, and a full 22 percent reverted to normal blood-glucose levels. Subjects who lost weight and/or lowered their systolic blood pressure were the most likely to bring their blood sugar levels back to normal.
