Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.
Because it is glucose-dependent, this class carries a low intrinsic hypoglycaemia risk on its own — the risk arrives when it is combined with insulin or a sulfonylurea, which usually need reducing.
What I actually want to know is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Tell me what I have not thought of.

Patient selection optimization for glycaemic control: emerging predictive biomarkers for GLP-1 agonist response include:
| Biomarker | Association | Evidence Level |
|---|---|---|
| Baseline BMI | Higher BMI → greater absolute weight loss | Strong |
| Fasting insulin | Higher insulin → better response | Moderate |
| GLP1R gene variants | rs6923761 → variable response | Preliminary |
| Baseline hsCRP | Higher CRP → greater CV benefit | Moderate |
| Early weight loss (4 wk) | ≥3% at 4 wks → strong predictor of ≥10% at 68 wks | Strong |
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: 23 → 15 → 7 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.

Mine went the same way, slower. Posting only so the count is not one.
From the other side of the consultation, briefly.
Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 119 | 105 | 91 | 83 |
| Insulin (fasting) | 25 | 13 | 11 | 6 |
| HOMA-IR | 5.5 | 3.5 | 1.9 | 1.3 |
| Uric Acid | 8.2 | 6.9 | 5.8 | 5.0 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 5.5 to near 1.0 is a metabolic transformation.
