8/19/2025
A1c reflects average glucose ~3 months; fasting glucose and OGTT look at shorter windows. Always use your lab's ranges.
What can skew A1c
- Anemia, hemoglobin variants, pregnancy, kidney/liver disease, recent transfusion.
Educational plan
- Confirm fasting/illness/meds (e.g., steroids).
- Lifestyle pillars: whole-food, higher-fiber pattern; regular activity; sleep; stress reduction.
- Discuss with clinician: home glucose/CGM; med classes (metformin, GLP-1 RA, SGLT2 inhibitors, basal insulin) based on comorbidities and goals.
