# Hemoglobin A1c

**HbA1c, or glycated hemoglobin**, is a critical marker for assessing long-term blood glucose control, with implications for longevity. Elevated HbA1c levels have been linked to a higher risk of cardiovascular diseases, stroke, and mortality, even in individuals without diabetes. Maintaining HbA1c within recommended levels is crucial not only for managing diabetes but also for enhancing cardiovascular health and potentially extending longevity.
