DEAR DOCTOR K: I have Type 2 diabetes. For years, my doctor emphasized the importance of tight blood sugar control. But I recently read that tight control might not make sense for everyone. Why not?
DEAR READER: Millions of people with diabetes, and their doctors, are asking themselves the same question. It's a confusing and controversial area. I'll do my best to put it in context and to explain my own views. People with Type 2 diabetes have high levels of blood sugar if they don't take medication that lowers their blood sugar level.
