An aneurysm is a dangerous bulge in a blood vessel wall that can rupture without warning—leading to life-threatening internal bleeding. While some aneurysms cause no symptoms until they burst, certain signs may appear as the aneurysm grows or leaks. Men are at higher risk for certain types (like abdominal aortic aneurysms), especially after age 65 or with risk factors like smoking, high blood pressure, or family history.
If you experience any of these symptoms—especially suddenly—seek emergency medical care immediately. A ruptured aneurysm is fatal in about 40% of cases, and half of those who reach the hospital alive don’t survive.
⚠️ Key Warning Signs by Type
1. Brain (Cerebral) Aneurysm – “The Worst Headache of Your Life”
- Sudden, severe headache unlike any before—often described as being “hit on the head”
- Nausea or vomiting
- Stiff neck
- Blurred or double vision
- Drooping eyelid
- Sensitivity to light
- Seizure or loss of consciousness
📌 This is a medical emergency—even if the headache fades. It could be a “sentinel leak,” a small rupture that precedes a larger one.
2. Abdominal Aortic Aneurysm (AAA) – Often Silent Until Rupture
