Aneurysm: Signs You Shouldn’t Ignore
An aneurysm is a weakened area in the wall of a blood vessel that causes it to bulge. Many aneurysms cause no symptoms until they grow large or rupture, which is why some can be dangerous.
Warning signs can depend on where the aneurysm is located:
Brain aneurysm
A ruptured brain aneurysm is a medical emergency. Warning signs may include:
- Sudden, severe headache (often described as the “worst headache of my life”)
- Neck stiffness
- Nausea or vomiting
- Sensitivity to light
- Loss of consciousness
- Confusion
- Seizures
- Weakness, numbness, trouble speaking, or vision changes
Abdominal aortic aneurysm (AAA)
Possible signs include:
- A deep, persistent pain in the abdomen or side
- A pulsating feeling or lump in the belly
- Sudden severe abdominal or back pain (possible rupture)
- Dizziness, fainting, rapid heartbeat, or signs of shock
Thoracic aortic aneurysm (in the chest)
Possible symptoms:
- Chest or upper back pain
- Shortness of breath
- Trouble swallowing
- Hoarseness
- Cough
Seek emergency help immediately if:
- You have sudden, severe chest, abdominal, or back pain.
- You experience a sudden “thunderclap” headache.
- You faint, become confused, have seizures, or develop stroke-like symptoms.
Risk factors for aneurysm include:
- High blood pressure
- Smoking
- Older age
- Family history of aneurysms
- Certain inherited connective tissue disorders
- Atherosclerosis (hardening of the arteries)
Prevention and monitoring
You can reduce risk by:
- Keeping blood pressure under control
- Avoiding tobacco
- Maintaining healthy cholesterol levels
- Getting medical screening if you have significant risk factors or a family history
Many aneurysms are found incidentally during imaging for another reason. If you are concerned about a specific symptom (for example, a headache, chest pain, or abdominal pain), tell me where the pain is, how it started, your age, and any risk factors, and I can help you understand what it may suggest and how urgent it might be.
