Multiple Aneurysms: Causes, Risks, and What You Should Know

Yes, a person can have multiple aneurysms simultaneously. Some individuals are born with familial aneurysmal disease, a genetic condition that predisposes them to develop multiple aneurysms throughout life. Additionally, having one aneurysm increases the likelihood of developing another, as shared risk factors—such as smoking, high blood pressure, and diabetes—contribute to new aneurysm formation.

Key Risk Factors

• Genetics: Family history of aneurysms or connective tissue disorders (e.g., Ehlers-Danlos, Marfan syndrome).
• Lifestyle: Smoking, heavy alcohol use, and uncontrolled hypertension.
• Medical conditions: Atherosclerosis, polycystic kidney disease, and certain infections.

Regular screening is recommended for first-degree relatives of aneurysm patients. If you have one aneurysm, discuss surveillance imaging with your doctor to monitor for others.
