An aneurysm is a weakened area in the wall of a blood vessel that can bulge outward. Some aneurysms cause no noticeable symptoms, while others may cause symptoms depending on their location and size.
Because symptoms can vary, it is important to know when sudden or unusual symptoms need urgent medical attention.
What Is an Aneurysm?
Aneurysms can develop in different parts of the body, including the brain and the aorta, the body’s main artery.
Many aneurysms are discovered during medical tests performed for other reasons. In some cases, an aneurysm may grow without causing obvious symptoms.
Possible Warning Signs
The signs depend on where the aneurysm is located. Potential symptoms can include:
A sudden, unusually severe headache
Sudden changes in vision
Difficulty speaking or understanding speech
Sudden weakness or numbness
Severe, sudden pain in the chest, back, or abdomen
Fainting or sudden confusion
New difficulty walking or maintaining balance
These symptoms can also be caused by other serious medical conditions, so they should not be ignored.
⚠️ When to Seek Emergency Help
Seek emergency medical care immediately if you or someone else develops a sudden severe headache, sudden weakness, trouble speaking, fainting, severe chest or back pain, or other sudden neurological symptoms.
Do not wait to see if severe symptoms improve on their own.
Risk Factors
Some factors associated with aneurysms include:
Older age
Smoking
High blood pressure
Family history of certain aneurysms
Certain inherited conditions
Having a risk factor does not mean that someone will definitely develop an aneurysm.
Can an Aneurysm Be Prevented?
Not all aneurysms can be prevented, but managing certain health factors may help reduce risk. This can include avoiding tobacco, managing blood pressure with professional guidance, staying physically active, and following medical advice for existing health conditions.
The Bottom Line
Many aneurysms do not cause symptoms until they become serious, which is why sudden and severe symptoms should always be taken seriously.
If you experience symptoms that could indicate a medical emergency, seek emergency care immediately. This article provides general information and is not a substitute for professional medical advice.
