is 5.9 a good a1c for a diabetic

An A1C level of 5.9% is generally considered excellent for someone with diabetes. Here's what it means:

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

For most people with diabetes, the target A1C is 7% or less, as recommended by the American Diabetes Association. An A1C of 5.9% indicates that your blood sugar levels are well-managed and close to the normal range. However, your specific target may vary based on your age, health conditions, and treatment plan. Always consult your doctor to confirm your ideal A1C goal.
