My A1c is 5.7 — what does that actually mean and what do I do?

First, breathe. An A1c of 5.7% sits at the very bottom edge of the prediabetes range (5.7–6.4%). It is not diabetes, and it is not a diagnosis you're stuck with — it's a warning light on the dashboard. A1c reflects your average blood sugar over roughly the last three months, so a 5.7 means your average has been creeping up a little, not that something has broken.

Here's the part nobody has time to tell you in a seven-minute appointment: a 5.7 is one of the most reversible numbers in all of medicine, precisely because you caught it this early. The big needle-movers are losing about 5% of your body weight if you're carrying extra, walking for 10–15 minutes after meals (this blunts the post-meal spike that drives A1c up), cutting liquid sugar first, and adding a little resistance training so your muscles soak up glucose.

The trap most people fall into is that A1c moves slowly, so they make changes, check again too soon or not at all, see nothing dramatic, and quit at week three. That's exactly backwards — the changes are usually working, you just can't feel it.

On Calqulate.net you can run the free Diabetes Risk Calculator to see which of your specific factors (weight, waist, activity, family history) are pushing your number up. Then Calqulate Vitals tracks your trajectory over the following months and tells you whether you're genuinely trending down or just seeing normal noise — so you keep going through the boring middle, which is where it actually pays off.
