An aneurysm is a bulge or ballooning in a blood vessel caused by weakness in the vessel wall. This can happen in various parts of the body, but it is most commonly found in the brain or aorta, the large artery that carries blood from the heart. If an aneurysm grows too large, it can rupture, leading to serious health issues like internal bleeding or stroke. Symptoms of an aneurysm can vary depending on its location. Some people may not experience any symptoms at all, while others might feel pain or pressure. Regular check-ups and imaging tests can help detect aneurysms early, allowing for timely treatment and reducing the risk of complications.
