My A1C dropped so fast my doctor thought the lab made an error

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.

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 = 5.5 (insulin resistant) → Current = 1.5 (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.

My labs after 6 months on glycaemic control: A1C 5.7%, fasting glucose 92 mg/dL, fasting insulin 5 uIU/mL. My endo says these are "textbook perfect."

For context, my baseline A1C was 7.9% and fasting glucose was 117 mg/dL. The improvement has been dramatic and consistent.

Mine went the same way, slower. I had assumed I was the exception until I read this.

From the other side of the consultation, briefly.

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

After 11 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.
