    Who Should Track Their Blood Sugar?

    Listened

    In progress

    Prediabetes is common in the U.S. — around 1 in 3 people have it. And many people may not know they have it. But last year, the FDA approved the first over-the-counter continuous glucose monitor. Since then, more people without diabetes have started checking their blood glucose levels. Diabetologist and University of California, San Francisco professor of medicine Dr. Sarah Kim shares the science behind blood glucose with host Emily Kwong.
