Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.
What I am after is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Numbers rather than impressions, if you have them.

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.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 125 | 107 | 89 | 85 |
| Insulin (fasting) | 21 | 15 | 9 | 5 |
| HOMA-IR | 5.5 | 3.1 | 1.7 | 1.4 |
| Uric Acid | 7.8 | 6.5 | 5.6 | 5.1 |
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.

This matches mine closely enough to be worth saying so out loud. The detail I would add is minor and it is already implied above.
From the other side of the consultation, briefly.
My labs after 6 months on glycaemic control: A1C 5.9%, fasting glucose 84 mg/dL, fasting insulin 7 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 8.3% and fasting glucose was 119 mg/dL. The improvement has been dramatic and consistent.
