Understanding Abdominal Aortic Aneurysms (AAAs): What You Need to Know
An abdominal aortic aneurysm (AAA) might sound like complicated medical jargon, but understanding what it is could potentially save your life or the life of someone you love. Let me walk you through what this condition is in simple terms.
What is an Abdominal Aortic Aneurysm?
Imagine your aorta—the main pipeline carrying blood from your heart to the rest of your body—as a garden hose. Now, picture a section of that hose developing a bulge or balloon-like swelling in your abdomen (the area between your chest and hips). That’s essentially what an abdominal aortic aneurysm is.
This bulging happens when the walls of the aorta weaken and stretch outward. The danger lies in the fact that, like an overfilled balloon, this weakened section could eventually burst—a life-threatening emergency that requires immediate medical attention.

How Do AAAs Typically Develop?
AAAs don’t usually happen overnight. They often develop slowly over years, sometimes decades. What’s particularly concerning is that many people with AAAs don’t experience any symptoms until the situation becomes serious.
The aneurysm typically forms in the section of the aorta that passes through your abdomen. As it gradually enlarges, the risk of rupture increases—and a ruptured aneurysm is a medical emergency with a high mortality rate.
What Causes an Abdominal Aortic Aneurysm?
Several factors can contribute to the development of an AAA:
Atherosclerosis: This is the buildup of fatty deposits (plaque) in your arteries, which can weaken the aortic wall. Think of it as rust forming inside a pipe, making it more vulnerable to damage.
Aging: As we get older, our blood vessels naturally lose some elasticity, making them more susceptible to aneurysms. This is why AAAs are more common in people over 65.
Genetic factors: Some people inherit conditions that affect their connective tissue, making their aorta more vulnerable to weakening.
Lifestyle factors: Smoking is perhaps the most significant controllable risk factor. High blood pressure, high cholesterol, and obesity also increase your risk.
Gender: Men are more likely to develop AAAs than women, though women with AAAs face a higher risk of rupture.
Recognizing the Warning Signs
Many AAAs don’t cause symptoms, which is why they’re often discovered during routine exams or tests for other conditions. However, some people might experience:
- A pulsing feeling near the navel
- Deep, constant pain in the abdomen or side of the abdomen
- Back pain
- A feeling of fullness after eating only a small amount
If an aneurysm ruptures, symptoms can include sudden, intense abdominal or back pain, dizziness, rapid heart rate, and loss of consciousness. This requires immediate emergency care.
Preventing and Managing AAAs
While we can’t control all risk factors, there are steps you can take to reduce your risk:
Quit smoking: If you smoke, this is the single most important thing you can do to reduce your risk.
Manage blood pressure: Regular check-ups and taking prescribed medications as directed can help keep your blood pressure in check.
Eat heart-healthy foods: A diet rich in fruits, vegetables, whole grains, and lean proteins can help maintain arterial health.
Stay active: Regular, moderate exercise strengthens your heart and blood vessels.
Maintain a healthy weight: Excess weight puts additional strain on your cardiovascular system.
If you’ve already been diagnosed with a small AAA, your doctor will likely recommend:
- Regular monitoring through ultrasound or CT scans
- Blood pressure control
- Lifestyle modifications
- Possibly medications to slow the aneurysm’s growth
For larger aneurysms or those growing rapidly, surgical repair may be necessary to prevent rupture.
When to Seek Medical Attention
If you’re over 65, have a family history of AAA, or have risk factors like smoking or high blood pressure, talk to your doctor about screening. The U.S. Preventive Services Task Force recommends one-time screening for men aged 65-75 who have ever smoked.
Remember, many people with AAAs don’t experience symptoms until an emergency occurs. Being proactive about your vascular health, especially if you have risk factors, could potentially save your life.
Living with the knowledge of an AAA can be stressful, but many people with small aneurysms never experience serious problems, especially with proper monitoring and care. Work closely with your healthcare provider to develop the right plan for your situation.
Your health journey is unique, and understanding conditions like AAA empowers you to make informed decisions about your wellbeing.
