Over time, the wall can become so thin that it tears or breaks, which can lead to life-threatening bleeding.
Why is this information important?
Aneurysms are dangerous not only because of the risk of rupture, but also because they are often invisible until it is too late.
Understanding the facts helps people to:
Recognize warning signs early.
Identify personal risk factors.
Seek timely medical attention.
Even before the breakup, or right at the moment it begins, your body may send subtle or sudden signals:
Possible early signs of an aneurysm (without rupture):
Pain behind or above one eye
; dilated pupil;
blurred or double vision
; drooping eyelid;
numbness or weakness on one side of the face
These symptoms occur when the aneurysm presses on nearby nerves.
Emergency signs of rupture:
Sudden, severe headache (the worst you’ve ever had)
Nausea and vomiting
Stiff neck
Sensitivity to light
Confusion or loss of consciousness
Seizures
This is a medical emergency. Call emergency services immediately.
