Statin with diabetes — should I, and is it worth it?
For you, or for someone you care for — a partner, a parent.
Two worries bring people here. One: "I have diabetes and I'm being offered a statin even though my cholesterol feels fine." The other: "I'm on a statin and I'm scared it's pushing my sugar up — should I stop?" Both are real, and both sit on the same trade-off. This page doesn't tell you whether to start, keep, or stop the tablet. It shows you the two risks side by side at their honest sizes — the heart attacks and strokes a statin prevents in someone with diabetes, next to the small extra blood-sugar risk it carries — and hands you the questions to settle it with your GP.
This helps you prepare a conversation — it can't tell if something is urgent right now. If you feel unwell, call 000 or your GP.

Your inputs
The reframe
The two risks, side by side
Heart-and-stroke protection
What a statin buys someone with diabetes-level heart risk
a meaningful group in 100 spared a heart attack or stroke over ≈5 years, because diabetes already loads the heart risk.
Extra blood-sugar / diabetes risk
What the statin costs on the sugar side
about 2–3 in 100 diagnosed with diabetes over ≈5 years who might not have been yet — concentrated in people already near the threshold.
spared a heart attack or stroke (filled circle) extra diabetes diagnosis (open square) no measurable difference either way (muted circle)
Trial-population figures (statin RCTs + the AU diabetes-CVD guideline) — not your personal numbers. Your own figures come from your GP and the AusCVDRisk calculator.
What's my actual heart-and-stroke risk — the real number from the Australian calculator — so we're weighing the statin against something concrete?
Question 2
How much does my diabetes already add to that risk, and how much does the statin lower it for me?
Question 3
If we're worried about my blood sugar, can we watch and manage it while I stay protected — rather than stopping the statin? What dose makes sense?
