What actually is an aortic aneurysm?
A swelling in the main artery running down through your abdomen. The wall weakens and stretches over years.
It causes nothing at all until it bursts, which is why it is screened for rather than waited for.
Does the scan hurt?
Not at all. Gel on your stomach and a probe moved over it for a few minutes.
No needles, no radiation, no fasting, no preparation. You can eat beforehand and drive afterwards.
Why only once?
Because a normal aorta at 65 very rarely becomes dangerous later. The evidence supports a single scan at that age.
If yours is normal you are discharged, and that is a genuine answer rather than a cost saving.
Why are women not offered it?
Because screening has not been shown to produce the same benefit in women. Aneurysms are much less common in women and behave differently.
Women with a strong family history or symptoms should still be assessed individually — the programme's absence is not a statement that it never happens.
I am 71 and was never invited. Can I still go?
Yes — contact your local AAA screening service and refer yourself. No GP referral needed.
Being older is a reason to do it, not a reason you have missed the window.
They found a small aneurysm. Do I need an operation?
Almost certainly not. Most small aneurysms never reach the size at which surgery is worthwhile.
Surveillance is the safer option below 5.5cm, because the risk of the operation exceeds the risk of rupture at that size.
What is the most useful thing I can do if I have one?
Stop smoking. It is by a distance the biggest influence on how fast an aneurysm grows.
Also: keep blood pressure controlled, stay active, and attend the follow-up scans. NHS stop smoking services are free.
Does it run in families?
Yes — having a father or brother with one raises your risk substantially.
Mention it to your GP rather than waiting for 65, since earlier surveillance is sometimes offered to first-degree relatives.
Will it affect my driving licence?
Only if it becomes large. Car drivers must notify the DVLA at 6cm and stop driving at 6.5cm; lorry and bus licences have stricter limits.
If you drive for a living, raise this early — it is frequently not mentioned until it becomes a problem.
Should I pay for a private scan instead?
No reason to. The NHS scan is free, quick and uses the same ultrasound.
If you are outside the programme, self-referral costs nothing — use that before paying anyone.
