My labs after 12 months on glycaemic control: A1C 6.1%, fasting glucose 86 mg/dL, fasting insulin 9 uIU/mL. My endo says these are "textbook perfect."

For context, my baseline A1C was 6.7% and fasting glucose was 121 mg/dL. The improvement has been dramatic and consistent.

Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.

Patient selection optimization for glycaemic control: emerging predictive biomarkers for GLP-1 agonist response include:

The 4-week early responder criterion is the most clinically actionable: if you haven't lost ≥3% by week 4 at a therapeutic dose, discuss optimization strategies with your provider.

Fasting insulin is the lab my functional medicine doctor cares about most for glycaemic control: it's a much earlier marker of metabolic dysfunction than glucose or A1C.

My fasting insulin: 28 → 12 → 6 uIU/mL over 9 months. Target is <7. By the time your fasting glucose is elevated, your insulin has been elevated for YEARS trying to compensate.

Ask your doctor to include fasting insulin in your bloodwork panel. It's cheap (~$20) and incredibly informative.

Following on from ZaraB_AL — and this may be the naive question:

Was that from a primary source or from a summary of one?

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 39% to 20%. Target is <36%, with <30% being ideal.

Why this matters more than average glucose: large glucose swings cause oxidative stress, endothelial damage, and promote advanced glycation end-products (AGEs). A flat glucose line at 95 mg/dL is metabolically healthier than oscillating between 60 and 160, even if the average is the same.
