is 5.8 prediabetes

Yes, an A1C level of 5.8% falls within the prediabetes range. According to the CDC and other medical guidelines:

• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or above

If your A1C is 5.8%, it indicates that your blood sugar levels are higher than normal but not high enough to be classified as diabetes. This is a warning sign, and lifestyle changes such as improving your diet, increasing physical activity, and losing weight (if needed) can help prevent or delay the progression to type 2 diabetes. Consult your healthcare provider for personalized advice and a follow-up testing schedule.
