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

My labs after 6 months on glycaemic control: A1C 5.0%, fasting glucose 80 mg/dL, fasting insulin 7 uIU/mL. My endo says these are "textbook perfect."

For context, my baseline A1C was 7.5% and fasting glucose was 125 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.

Insulin sensitivity test (HOMA-IR) on glycaemic control — arguably the most important metabolic marker most people aren't tracking:

HOMA-IR = (fasting insulin × fasting glucose) ÷ 405

My numbers: Baseline HOMA-IR = 5.9 (insulin resistant) → Current = 1.3 (insulin sensitive)

Anything above 2.0 indicates insulin resistance. The goal is below 1.5. GLP-1 agonists address the root metabolic dysfunction, not just the symptoms. This is why they work so much better than calorie restriction alone.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:

HOMA-IR5.54.22.11.5
Uric Acid8.97.16.05.2

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.

One thing that is still open after carlos_SATX’s answer:

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

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: 25 → 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.
