Smoking damages more than your lungs. The chemicals in cigarette smoke weaken artery walls, trigger inflammation and accelerate plaque buildup throughout your vascular system, including the abdominal aorta.
An abdominal aortic aneurysm (AAA) is a bulge in this major artery. It grows silently for years and research shows smoking increases AAA risk by 4 to 8 times compared to non-smokers.
What Smoking Does to the Aorta
Cigarette smoke contains over 7,000 chemicals. Many break down the elastic fibers that give artery walls their strength. When these fibers deteriorate, the aortic wall can no longer withstand normal blood pressure and bulges begin to form.
Inflammation and Oxygen Loss
Smoking triggers chronic inflammation that weakens structural proteins in artery walls. It also activates enzymes that break down the proteins holding the aortic wall together. Carbon monoxide from cigarettes reduces oxygen in the blood, limiting the artery’s ability to repair everyday wear.
The effects of smoking on veins and arteries extend well beyond the aorta, impacting your entire vascular system.
Why AAA Grows Without Warning
An aneurysm under 5 centimeters typically produces no symptoms. You feel normal while the bulge slowly expands.
When Symptoms Appear
Some people notice deep abdominal pain, back pain, or a pulsing sensation near the navel as the aneurysm enlarges. These are vague and easily mistaken for other conditions.
The Rupture Risk
When an AAA ruptures, approximately 80% of people die before reaching the hospital or during emergency treatment. Early detection is the only reliable defense.
Who Should Get Screened for AAA
| Risk Factor | Screening Recommendation |
| Men 65-75 who have ever smoked | One-time ultrasound strongly recommended |
| Men 65-75 who never smoked | Consider if family history present |
| Women 65-75 with smoking history | Discuss with your doctor |
| Family history of AAA | Screening recommended regardless of smoking |
AAA risk increases with age as arteries lose elasticity. Combined with decades of smoking damage, this creates peak risk between 65 and 75. Women with AAA face rupture at smaller sizes and should not assume low risk.
Signs That Need Immediate Attention
Emergency Warning Signs
Call 911 immediately for sudden severe abdominal pain, intense unexplained back pain, a visible pulsing sensation in the abdomen, fainting, clammy skin with rapid heartbeat, or sudden weakness combined with severe pain.
Symptoms Worth Evaluating
Persistent deep abdominal discomfort, unresponsive back pain, or awareness of abdominal pulsing combined with smoking history and age over 60 warrant a vascular evaluation.
How Quitting Smoking Affects AAA Risk
Quitting provides real vascular benefits, though it does not erase decades of accumulated damage.
What Improves After Quitting
Quitting slows aneurysm growth, lowers rupture rates compared to current smokers and reduces surgical complications if repair is ever needed. It also protects your heart, brain and kidneys. Smokers with reduced blood flow to the legs may also benefit from peripheral arterial disease treatment.
Screening Still Applies
Even quitting after age 60 provides measurable benefits. However, a significant smoking history still warrants screening regardless of when you quit.

What AAA Screening Involves
Screening is painless and takes 10 to 15 minutes. A technician uses an ultrasound probe on your abdomen to measure the aorta’s diameter.
Understanding Your Results
- Normal aorta: Less than 3 cm
- Small aneurysm: 3 to 4.4 cm (monitoring recommended)
- Medium aneurysm: 4.5 to 5.4 cm (closer monitoring)
- Large aneurysm: 5.5 cm or greater (treatment typically recommended)
How AAA Is Treated Once Detected
Finding an aneurysm does not automatically mean surgery.
Monitoring and Medical Management
Aneurysms under 5.5 cm with slow growth are watched with periodic ultrasounds. Blood pressure control is critical because high blood pressure accelerates growth.
Surgical Repair Options
When aneurysms reach 5.5 cm or grow rapidly, surgery becomes the next step. A vascular surgeon recommends the best approach based on aneurysm size, location and overall health. Early detection gives patients access to effective AAA treatment before rupture becomes a risk.
Protect Yourself Before Symptoms Appear
Get Screened if You Qualify
If you are between 65 and 75 and have ever smoked regularly, a one-time ultrasound could save your life. Do not wait for symptoms because most aneurysms cause none until they become dangerous.
Early Detection Changes Outcomes
Small aneurysms can be safely monitored. Larger ones can be repaired before rupture occurs. Modern treatment options are highly effective when applied at the right time.
