Hemoglobin A1c
glucose
Hemoglobin A1c reflects your average blood sugar over roughly the past three months. Your value of 5.9% is above your lab's range and falls in the 5.7–6.4% band the American Diabetes Association classifies as prediabetes range. Your A1c has risen significantly across your last three results — a real upward trend, not normal fluctuation. Habits that support healthy blood sugar include reducing refined carbs, increasing regular activity, and managing weight. Because this trend is meaningful, discuss follow-up with your doctor.
