Abdominal Aortic Aneurysm (AAA) Causes and Symptoms

Jan 25, 2024

An abdominal aortic aneurysm (AAA) is a bulge or ballooning in the lower part of the aorta, the main artery that carries blood from your heart to your abdomen and legs. The aorta normally has a diameter of about 2 centimeters, but with an AAA, it can bulge to several times that size.

Here's a breakdown of AAA:

Causes:

  • Atherosclerosis: The most common cause of AAA, this is a buildup of fatty deposits (plaque) in the artery walls that weakens them.
  • High blood pressure: Puts additional strain on the aorta, making it more likely to bulge.
  • Smoking: Damages the aorta and promotes atherosclerosis.
  • Family history: If your close relatives have had an AAA, you're at higher risk.
  • Age: AAA is more common in people over 65.
  • Gender: Men are more likely to develop AAA than women.

Symptoms:

  • Most AAAs don't cause any symptoms until they rupture.
  • If you do have symptoms, they may include:
    • A pulsating feeling in your abdomen
    • A deep, constant pain in your abdomen or back
    • Feeling full or unable to eat much
    • Nausea or vomiting
    • Fatigue

Complications:

The most serious complication of AAA is rupture, which is a medical emergency. A ruptured AAA can cause severe internal bleeding and is often fatal.

Treatment:

Treatment for AAA depends on the size of the aneurysm and whether it's causing symptoms.

  • Small AAAs: If the AAA is small and not causing symptoms, your doctor may recommend monitoring it with regular ultrasounds.
  • Large AAAs: If the AAA is large or causing symptoms, your doctor may recommend surgery to repair or replace the affected part of the aorta.

Prevention:

You can reduce your risk of AAA by:

  • Quitting smoking
  • Controlling your blood pressure
  • Maintaining a healthy weight
  • Exercising regularly
  • Eating a healthy diet
