AAA stands for Abdominal Aortic Aneurysm. The aorta is the main blood vessel that supplies blood to your body. It runs from your heart down through your chest and abdomen.
In some people, as they get older, the wall of the aorta in the abdomen can become weak. It can then start to expand and form what is called an abdominal aortic aneurysm. The condition is most common in men aged 65 and above. Men are six times more likely to have an aneurysm than women and your risk of having an aneurysm increases if you are or have been a smoker, you have high blood pressure or you have a close family member who has had one.
If you have an AAA you will not usually notice any signs or symptoms; this means you cannot tell if you have one, will not feel any pain or notice anything different. Large aneurysms are rare but can be very serious. As the wall of the aorta stretches it becomes weak and can burst, causing internal bleeding. Over 80% people die when an aneurysm bursts.
An aorta that is only slightly larger than normal is not necessarily dangerous; however, it is still important to know about it so that we can check if the aneurysm is getting bigger.
AAA screening is a free NHS national programme that screens men aged 65 plus to check if they have an abdominal aortic aneurysm. We offer screening so we can find aneurysms early and monitor or treat them.
