An Aneurysm is a weakened, bulging area in the wall of a blood vessel. Many aneurysms cause no symptoms until they grow large or rupture, so they can go unnoticed.
Signs you shouldn’t ignore
The symptoms depend on where the aneurysm is located.
Possible signs of a brain aneurysm (especially if it ruptures):
- Sudden, extremely severe headache (“the worst headache of your life”)
- Nausea and vomiting
- Stiff neck
- Blurred or double vision
- Sensitivity to light
- Confusion, seizures, or loss of consciousness
Possible signs of an aortic aneurysm:
- Sudden, severe chest, back, or abdominal pain
- Pain that may spread to the back or legs
- Dizziness, fainting, or signs of shock if it ruptures
- A pulsating feeling in the abdomen (sometimes)
When to seek emergency care
Call your local emergency services immediately if someone develops:
- A sudden, severe headache unlike any they’ve had before
- Sudden severe chest, back, or abdominal pain
- Fainting, loss of consciousness, or symptoms of a stroke (such as weakness on one side or difficulty speaking)
Risk factors
Factors that can increase the risk of an aneurysm include:
- High blood pressure
- Smoking
- Older age
- A family history of aneurysms
- Certain inherited connective tissue disorders
The phrase “signs you shouldn’t ignore” is reasonable in the sense that these symptoms can indicate a medical emergency, but it’s also important to know that many aneurysms produce no warning signs before they’re discovered or rupture. If you have concerns because of your personal or family medical history, discussing screening with a healthcare professional may be appropriate.
