DEAR DOCTOR K: After years of normal blood sugar levels, I'm suddenly in the prediabetes range. Am I on an irreversible path to Type 2 (adult-onset) diabetes?
DEAR READER: No, you're not, but you're facing a challenge. Prediabetes is an early warning signal: You are at higher risk for developing diabetes. But diabetes is not inevitable. In fact, we know more about how to reduce the risk of getting Type 2 diabetes than we know about preventing most other major diseases. There are several things you can do to reverse course.
