An aneurysm is a weakened, bulging area in a blood vessel. Many cause no symptoms until they become large, leak, or rupture — which can be life-threatening. (Mayo Clinic)
Signs that need urgent medical attention can include:
- Sudden, extremely severe headache (“worst headache of your life”)
- Sudden chest, back, or abdominal pain
- Blurred or double vision
- Nausea, vomiting, confusion, or fainting
- Weakness, trouble speaking, or seizure
- A pulsating feeling in the abdomen
- Shortness of breath or sharp pain spreading through the back or chest (Mayo Clinic)
Risk factors include:
- Smoking
- High blood pressure
- Family history of aneurysms
- Older age
- Certain genetic/connective tissue disorders (Mayo Clinic)
If someone develops sudden severe symptoms — especially a thunderclap headache or tearing chest/back pain — it’s considered a medical emergency and emergency services should be contacted immediately. (Mayo Clinic)
