does high hemoglobin mean diabetes

High hemoglobin levels do not necessarily mean diabetes. Hemoglobin is a protein in red blood cells that carries oxygen. However, the hemoglobin A1C (HbA1c) test, which measures the percentage of hemoglobin coated with sugar, is used to diagnose and monitor diabetes. Here’s what you need to know:

• Normal A1C: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or above

High hemoglobin levels could be due to other factors like dehydration, smoking, or living at high altitudes. If you suspect diabetes, consult a healthcare provider for an A1C test or other diagnostic measures.
