An aneurysm occurs when a blood vessel wall weakens, causing it to bulge or balloon. While some aneurysms develop slowly without causing any immediate problems, others can rupture suddenly, leading to life-threatening complications. Early recognition of symptoms is crucial for prevention and timely treatment.

What Is an Aneurysm?

An aneurysm is an abnormal dilation of a blood vessel, most commonly affecting arteries in the brain (cerebral aneurysm) or the main artery in the body (aortic aneurysm). Risk factors include high blood pressure, smoking, high cholesterol, and a family history of aneurysms.

Common Symptoms to Watch For

Symptoms vary depending on the location of the aneurysm:

1. Brain (Cerebral) Aneurysm

Sudden, severe headache described as “the worst headache of my life”

Nausea or vomiting

Vision problems, such as blurred or double vision

Drooping eyelids

Stiff neck

Sensitivity to light

2. Aortic Aneurysm (Chest or Abdomen)

Severe, sudden chest or back pain

A pulsating feeling near the navel (for abdominal aneurysms)

Shortness of breath or difficulty swallowing (chest aneurysms)

Low blood pressure, rapid heartbeat, or fainting (if ruptured)

3. Peripheral Aneurysm (Limbs)
