Glucose Measurement Challenges
- Measuring glucose is crucial for diabetes diagnosis, but glucose fluctuates greatly.
- Random, fasting, or glucose tolerance tests each have limitations in capturing the full picture.
Post-Prandial Hyperglycemia Significance
- Fasting glucose misses post-prandial hyperglycemia, an early diabetes indicator.
- Steroids and GLP-1 agonists primarily affect post-prandial glucose, not fasting levels.
HbA1c: A Long-Term Average
- Hemoglobin A1c (HbA1c) measures average glucose by assessing glucose bound to hemoglobin over time.
- It acts as a long-term average, similar to how left atrial size reflects heart health.
