Can you have insulin resistance with a normal A1C?

Short answer
Yes. A1C reflects average blood glucose over roughly three months, not how hard your body works to keep glucose normal. Early insulin resistance is often hidden behind compensatory high insulin until A1C drifts into the prediabetes range.
Detailed answer
Normal A1C does not rule out metabolic strain. Discuss symptoms (waist gain, post-meal fatigue, cravings), blood pressure, triglycerides, and whether additional labs are appropriate with your clinician.
