An aneurysm is a potentially serious condition that occurs when a weakened area in the wall of a blood vessel bulges outward. Many aneurysms cause no symptoms at all until they become large or rupture, which is why understanding possible warning signs is important.
What Is an Aneurysm?
An Aneurysm can develop in different parts of the body, including the brain and the body’s largest artery, the aorta.
Common types include:
- Brain aneurysm
- Abdominal aortic aneurysm
- Thoracic aortic aneurysm
Possible Warning Signs
Symptoms depend on the location and size of the aneurysm.
Brain Aneurysm
An unruptured aneurysm may cause:
- Headaches
- Pain above or behind one eye
- Blurred or double vision
- Drooping eyelid
- Dilated pupil
A ruptured brain aneurysm is a medical emergency and may cause:
- Sudden, severe headache (“worst headache of my life”)
- Nausea and vomiting
- Stiff neck
- Sensitivity to light
- Confusion
- Seizures
- Loss of consciousness
Abdominal Aortic Aneurysm
Possible symptoms include:
- Deep, persistent abdominal pain
- Back pain
- A pulsing sensation in the abdomen
A rupture can cause:
- Sudden severe abdominal or back pain
- Dizziness
- Fainting
- Shock
Thoracic Aortic Aneurysm
Symptoms may include:
- Chest pain
- Back pain
- Hoarseness
- Shortness of breath
- Difficulty swallowing
Risk Factors
Factors that increase the risk of aneurysms include:
- Smoking
- High blood pressure
- Older age
- Family history
- Atherosclerosis (hardening of the arteries)
When to Seek Immediate Medical Help
Call emergency services immediately if someone develops:
- A sudden, severe headache
- Sudden chest, abdominal, or back pain
- Loss of consciousness
- Symptoms of stroke
These may indicate a ruptured aneurysm or another life-threatening emergency.
Important Reality Check
Many aneurysms produce no symptoms before they are discovered. Some are found during routine imaging tests performed for unrelated reasons. That’s why controlling risk factors—especially smoking and high blood pressure—is so important.
Final Thoughts
An Aneurysm can be dangerous, particularly if it ruptures. While symptoms vary depending on location, sudden severe headache, chest pain, abdominal pain, or signs of stroke should never be ignored. If you experience any of these warning signs, seek emergency medical attention immediately.
