The glycated hemoglobin (HbA1c) test is the most important test for monitoring diabetic patients providing a complete picture of average blood sugar levels over the past 2-3 months — not instantaneously like regular blood sugar tests.
How HbA1c Affects the Foot:
- HbA1c above 7%: Increases neuropathy risk at an accelerating rate. Each 1% increase in HbA1c raises ulcer risk by 25-30%.
- HbA1c above 8%: Noticeably slows wound healing, weakens the immune system, and increases infection risk.
- HbA1c above 9%: Very high risk — white blood cells don't work efficiently and blood vessels deteriorate rapidly.
Ideal Targets:
Below 7% to prevent complications. Below 6.5% if possible without frequent hypoglycemia. But in elderly or complex patients, 7.5-8% may be acceptable.
Does Blood Sugar Control Affect Existing Wounds:
Yes! Even if HbA1c has been high for years — good control now improves healing immediately because white blood cells function better with controlled blood sugar.
At BEIT TARIQ Center, we request HbA1c at the first visit, monitor it every 3 months, and coordinate with the diabetes doctor to improve it.
