An aneurysm is a bulge or weakening in a blood vessel wall. The danger is that it can enlarge and rupture, which is a medical emergency.
Aneurysm symptoms are often silent until something serious happens, but there are warning signs you shouldn’t ignore—especially depending on where the aneurysm is (brain, aorta, etc.).
🚨 Possible warning signs of a brain aneurysm (or rupture)
If an aneurysm in the brain leaks or bursts, symptoms can come on suddenly:
- Sudden, severe headache (often described as “worst headache of life”)
- Blurred or double vision
- Drooping eyelid or dilated pupil
- Stiff neck
- Nausea or vomiting
- Loss of consciousness
- Seizure
- Confusion or trouble speaking
⚠️ Possible warning signs of an aortic aneurysm (chest/abdomen)
These can be subtle until they become dangerous:
- Deep, constant pain in chest, back, or abdomen
- Pulsing feeling near the navel (abdominal area)
- Shortness of breath (if in chest)
- Sudden severe tearing pain (possible rupture)
- Dizziness, fainting, or shock symptoms
⛔ When to treat it as an emergency
Seek immediate medical help if there is:
- Sudden, intense pain (head, chest, or abdomen)
- Fainting or collapse
- Sudden neurological changes (speech, vision, weakness)
- Signs of shock (cold skin, rapid heartbeat, confusion)
Important note
Many aneurysms don’t cause symptoms until they grow large or rupture, which is why they’re often found incidentally on scans.
