My A1C dropped so fast my doctor thought the lab made an error — anyone have experience?

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 39% to 20%.

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: 27 → 13 → 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.

A1C went from 7.4 to 5.6 over nine months and my prescriber was more interested in the fasting insulin, which I did not expect.

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.

PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.

After 9 months: periods became regular for the first time in ever, testosterone levels normalized, acne cleared significantly, and — unexpectedly — my hormonal symptoms have almost completely resolved.

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.

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

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

My labs after 9 months on glycaemic control: A1C 5.5%, fasting glucose 85 mg/dL, fasting insulin 6 uIU/mL. My endo says these are "textbook perfect."

For context, my baseline A1C was 6.5% and fasting glucose was 130 mg/dL. The improvement has been dramatic and consistent.
