Aneurysm: Warning Signs You Shouldn’t Ignore
An aneurysm is a weakened area in the wall of a blood vessel that bulges outward. Many aneurysms cause no symptoms and are found accidentally, but if one grows, leaks, or ruptures, it can become a medical emergency.
Possible warning signs of an aneurysm
1. Sudden, severe “worst headache of your life”
A ruptured brain aneurysm may cause:
- A sudden explosive headache
- A headache that feels very different from usual
- Nausea or vomiting
- Neck stiffness
This requires emergency medical attention.
2. Vision changes or eye symptoms
A brain aneurysm can sometimes press on nearby structures, causing:
- Blurred or double vision
- Drooping eyelid
- Pain around the eye
- Enlarged pupil
3. Weakness, numbness, or trouble speaking
Possible signs include:
- Weakness on one side of the body
- Difficulty speaking or understanding speech
- Confusion
- Loss of coordination
4. Chest, back, or abdominal pain (depending on location)
An aneurysm in the aorta (the body’s largest artery) may cause:
- Sudden severe chest or back pain
- Abdominal pain or a pulsating feeling in the abdomen
- Lightheadedness or fainting if rupture occurs
5. A sudden change in symptoms
Any sudden neurological or severe pain symptoms should be treated seriously.
Risk factors that increase aneurysm risk
- High blood pressure
- Smoking
- Older age
- Family history of aneurysms
