An aneurysm is a weakened area in a blood vessel wall that bulges outward. Many aneurysms cause no symptoms until they become large or rupture, which is why some are discovered during imaging done for another reason.
🚨 Signs of an aneurysm that should not be ignored
Possible brain (cerebral) aneurysm warning signs
A ruptured brain aneurysm is a medical emergency. Symptoms may include:
- Sudden, severe “worst headache of your life”
- Neck stiffness
- Nausea or vomiting
- Sensitivity to light
- Loss of consciousness or fainting
- Seizure
- Sudden weakness, numbness, confusion, trouble speaking, or vision changes
An unruptured brain aneurysm may sometimes cause:
- Pain above or behind an eye
- A drooping eyelid
- Double vision
- Changes in vision
- Difficulty moving an eye
Possible aortic aneurysm warning signs
Depending on location, symptoms may include:
- Chest or upper back pain
- Deep, constant abdominal or back pain
- A pulsating feeling in the abdomen
- Shortness of breath or trouble swallowing (in some cases)
Seek emergency care immediately if:
- You have a sudden, extremely severe headache.
- You have sudden neurological symptoms (face drooping, arm weakness, speech difficulty, confusion).
- You develop sudden severe chest, back, or abdominal pain.
Risk factors that can increase aneurysm risk
- High blood pressure
- Smoking
- Family history of aneurysms
- Older age
- Certain inherited connective tissue disorders
- High cholesterol and vascular disease
Many aneurysms are treatable when found early, so people with risk factors or concerning symptoms should discuss evaluation with a healthcare professional.
