What A1c level is too high?

5.7-6.4% is prediabetes. 6.5% or higher is diabetes. Below 5.7% is normal.

Can a high A1c be reversed?

Prediabetes (5.7-6.4%) is often reversible with weight loss, exercise, and dietary changes. Even diabetes A1c can be significantly improved with treatment.

What should I do if my A1c is high?

If prediabetic, start with lifestyle changes (reduce refined carbs, increase exercise, lose 5-7% body weight). If diabetic, see your doctor for a treatment plan.

How often should I retest?

Every 3 months if managing diabetes. Every 6 months if monitoring prediabetes. JustLabs offers A1c for $7.

Can I order follow-up tests?

Yes. Order A1c ($7), fasting glucose ($6), and fasting insulin ($14) together for a complete diabetes assessment.

HbA1c Alto: Qué Significa y Qué Hacer

A high A1c means your average blood sugar has been elevated over the past 2-3 months. An A1c of 5.7-6.4% indicates prediabetes; 6.5% or higher indicates diabetes. Prediabetes is often reversible with lifestyle changes, and diabetes is manageable with treatment.

¿Qué Causa HbA1c Alto?

Type 2 Diabetes

Your body has become resistant to insulin or doesn't produce enough, causing chronically elevated blood sugar.

Prediabetes

Blood sugar is higher than normal but not yet in the diabetic range. Affects 96 million American adults.

Insulin Resistance

Your cells don't respond effectively to insulin, forcing your pancreas to produce more. Often precedes prediabetes.

Medications

Corticosteroids, some antipsychotics, and certain other medications can raise blood sugar and A1c.
