Most aneurysms cause no symptoms at all. In fact, many are discovered accidentally during imaging tests performed for unrelated reasons.
However, some aneurysms-particularly those in the brain-can grow large enough to press on nearby nerves and tissues before they rupture. When that happens, warning signs may appear.
Understanding these symptoms could help someone seek medical attention before a life-threatening emergency occurs.
What Is an Aneurysm?
An aneurysm is a weakened area in the wall of a blood vessel that bulges outward, somewhat like a balloon.
They can occur in various parts of the body, including:
- The brain (cerebral aneurysm)
- The aorta (the body’s largest artery)
- Other blood vessels
The greatest danger occurs when an aneurysm ruptures, causing internal bleeding.
12 Possible Warning Signs
It’s important to remember that these symptoms can have many causes besides an aneurysm. However, persistent, unusual, or sudden symptoms should never be ignored.
