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 trying to establish is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Happy to be told the question itself is wrong.

PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.
After 8 months: periods became regular for the first time in a decade, testosterone levels normalized, acne cleared significantly, and — unexpectedly — my fertility specialist is optimistic about future conception.
GLP-1 agonists address the insulin resistance at the root of PCOS. For PCOS patients, this isn't "just" a weight loss drug — it's treating our underlying metabolic dysfunction.

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.

Adding a me-too, because a thread of one person's experience is not much use. Posting only so the count is not one.
Clinical perspective, offered as context rather than as advice.
Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 36% to 22%. 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.
