A1C from 7.2 to 5.1 — my results so far

AttorneyGrant said:

Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 42% to 19%. 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.

My labs after 3 months on glycaemic control: A1C 5.8%, fasting glucose 83 mg/dL, fasting insulin 6 uIU/mL. My endo says these are "textbook perfect."

For context, my baseline A1C was 8.1% and fasting glucose was 118 mg/dL. The improvement has been dramatic and consistent.

Can confirm. Same sequence, different timescale. I had assumed I was the exception until I read this.

Clinical perspective, offered as context rather than as advice.

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

After 7 months: periods became regular for the first time in years, testosterone levels normalized, acne cleared significantly, and — unexpectedly — I got pregnant naturally after 4 years of trying.

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.
