An abdominal aortic aneurysm, often called an AAA, is a serious but often silent condition that affects one of the body’s largest and most important blood vessels.
Because symptoms rarely appear until the aneurysm becomes large or ruptures, early detection through screening can save lives.
Understanding what an AAA is, what causes it, and how to test for it is key to preventing a life-threatening emergency.
What Is an Abdominal Aortic Aneurysm?
The aorta is the main artery that carries oxygen-rich blood from the heart to the rest of the body. When part of the aorta weakens and bulges outward in the abdomen, it forms an abdominal aortic aneurysm.
Over time, the wall of the artery can stretch further, making it thinner and more likely to tear or rupture. A ruptured aneurysm causes internal bleeding and is a medical emergency.
Many AAAs grow slowly and without symptoms, which is why routine screening is so important, especially for older adults and those with risk factors.
What Causes an Abdominal Aortic Aneurysm?
An AAA develops when the wall of the abdominal aorta becomes weakened, often due to a combination of genetic and lifestyle factors. As the artery weakens, blood pressure against the arterial wall causes it to expand.
Major Risk Factors
- Smoking (the single biggest risk factor)
- High blood pressure
- Atherosclerosis (plaque buildup in arteries)
- Family history of aneurysms
- High cholesterol
- Male sex (men are more likely to develop AAAs)
- Age over 60
- Obesity and inactivity
The risk increases with age and long-term exposure to habits or conditions that damage the vascular system.
How to Get Tested for an Abdominal Aortic Aneurysm
Because AAAs rarely cause symptoms, screening is the best way to detect them before they become dangerous.
Early detection allows doctors to monitor aneurysm size and plan treatment if necessary.
Common Screening Tests
- Abdominal ultrasound: The primary and most effective test. It uses sound waves to create images of the aorta and measure its size. It is quick, painless, and noninvasive.
- CT scan: Provides a detailed image of the aorta and is often used to confirm ultrasound findings or plan surgical repair.
- MRI scan: Another imaging option that can visualize the aneurysm in detail, though it is less commonly used for initial screening.
At Atlas Health Screening, our abdominal ultrasound screening identifies potential aneurysms early so you can take proactive steps to protect your health.
Recognizing the Warning Signs
Most abdominal aortic aneurysms develop silently, but if symptoms do occur, they may indicate a medical emergency. Seek immediate help if you experience:
- Sudden and severe abdominal or back pain
- A pulsating sensation in the abdomen
- Dizziness or low blood pressure
- Rapid heartbeat or fainting
These signs can point to a rupture, which requires urgent care.
Take the First Step Toward Prevention
Abdominal aortic aneurysms are often preventable and manageable when caught early.
Screening is quick, painless, and can provide life-saving information about your vascular health.
Whether you have risk factors or simply want peace of mind, early detection gives you the power to prevent complications before they occur.
