Living with Familial abdominal aortic aneurysm

A bulge in the main blood vessel in the belly that can run in families, most often in men aged 50 to 80.

Understanding Familial abdominal aortic aneurysm

Familial abdominal aortic aneurysm is a bulge (aneurysm) in the part of the aorta that passes through the belly, in a family with more than one affected person.

It can occur at any age but is most common in men between 50 and 80. Many people have no symptoms. Some feel a pulsing in the belly or have back pain. If the aneurysm tears, it can cause deep, severe pain, nausea, vomiting, a fast heartbeat, and clammy skin. It has genetic and environmental risk factors.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes:

  • Often no symptoms
  • A pulsing feeling in the belly
  • Back pain
  • Severe, deep pain if the aneurysm tears
  • Nausea and vomiting
  • Fast heartbeat

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
