Some health conditions creep in quietly. No warning, no pain—just silent changes happening inside your body. Abdominal Aortic Aneurysms, or AAAs, are one of those conditions. You might not feel a thing, but if left unchecked, an AAA can be life-threatening.
The good news? Knowing your risk is the first step toward staying safe.
At OC Surgeons, we specialize in vascular health and life-saving interventions for conditions like AAA. If you or someone you love is at risk, this blog is for you. Let’s break down what an abdominal aortic aneurysm really is—and who should be paying closer attention.
What Is an Abdominal Aortic Aneurysm (AAA)?
An abdominal aortic aneurysm is a bulge or ballooning in the lower part of the aorta—the major blood vessel that carries blood from your heart to the rest of your body. This section of the aorta runs through your abdomen. Over time, the weakened section of the artery can expand and, in severe cases, rupture. A ruptured AAA is a medical emergency that can be fatal without immediate treatment.
Most AAAs develop slowly and silently. That’s why it is important to understand the risk factors. The earlier an aneurysm is detected, the easier it is to manage—and in many cases, prevent serious complications.
The Top Risk Factors for AAA
While anyone can develop an abdominal aortic aneurysm, some individuals carry a significantly higher risk. Here’s what we want you to know:
Age
AAAs are far more common in individuals over 65. As we age, the walls of our arteries naturally lose some of their strength and elasticity, making them more vulnerable to damage.
Gender
Men are four to six times more likely to develop an AAA than women. That said, women are more likely to experience complications if they do have one, making screening important for both genders—especially with other risk factors in play.
Smoking
Smoking is the single most significant modifiable risk factor for AAA. It damages the aorta’s walls and dramatically increases the risk of developing and worsening an aneurysm. If you are a current or former smoker, especially over the age of 65, you may benefit from a screening test—even if you feel perfectly healthy.
Family History
If a close relative (parent, sibling, or child) has had an AAA, your own risk may be 2 to 3 times higher. Genetics play a real role, and family history should never be overlooked during health evaluations.
High Blood Pressure
Chronic high blood pressure puts extra stress on the walls of your arteries. Over time, this pressure can contribute to the development and growth of an aneurysm.
Atherosclerosis
This condition, also known as hardening of the arteries, results from plaque buildup in the arterial walls. It can weaken the vessel wall and allow for aneurysms to develop.
High Cholesterol
Elevated cholesterol levels contribute to atherosclerosis, indirectly increasing your risk of developing an aneurysm.
Other Contributing Factors
Certain conditions like chronic obstructive pulmonary disease (COPD), connective tissue disorders (such as Marfan syndrome), or a history of vascular inflammation may also increase your risk.
Why Risk Factor Awareness Matters
Because most AAAs don’t cause symptoms, many people don’t know they have one until it’s discovered during a routine imaging test—or worse, after a rupture.
That’s why early detection through screening is essential, especially if you meet any of the criteria above. A simple ultrasound can detect an aneurysm before it becomes dangerous. At OC Surgeons, we offer easy, non-invasive vascular screening that can give you peace of mind—or a path to early intervention.
What Can You Do If You’re at Risk?
Knowledge is power—and prevention is possible. Here’s what we recommend:
- Quit smoking or seek support to help you quit
- Control high blood pressure and cholesterol with lifestyle changes and medication
- Talk to your doctor about getting screened if you’re over 65 or have a family history of aneurysm
- Maintain regular checkups and stay informed about your vascular health
If an aneurysm is found, not every case will require surgery. Many can be monitored closely with imaging. But if it grows or becomes high-risk, we’re equipped to perform safe and effective repairs using modern techniques like endovascular aneurysm repair (EVAR).
FAQs About AAA and Risk Factors
Most people don’t know they have an AAA because it usually doesn’t cause symptoms. It’s often found incidentally during imaging for another issue. That’s why screening is so important if you’re in a high-risk group.
Yes, genetics play a role. If you have a first-degree relative who’s had an AAA, your risk is significantly increased. Be sure to mention any family history to your doctor so appropriate screening can be recommended.
Absolutely. Quitting smoking, eating a heart-healthy diet, managing blood pressure and cholesterol, and staying physically active all reduce the risk of developing an AAA or slowing its progression if one is already present.
Take Control of Your Vascular Health
You can’t change your age or your family history—but you can take proactive steps to understand your risk and catch problems early. At OC Surgeons, our experienced vascular specialists are here to help you do just that.
If you’re over 65, have a history of smoking, or have a family history of aneurysms, schedule a screening today. One simple test could make all the difference.
