What is the ballooning out of an artery and thinning of the artery wall is?

The ballooning out of an artery and thinning of the artery wall is a condition known as an aneurysm. It occurs when the wall of an artery becomes weak and bulges outwards like a balloon. Aneurysms may be caused by a variety of factors including aging high blood pressure and genetic disorders. If left untreated an aneurysm can rupture or tear leading to life-threatening bleeding.

Symptoms of an aneurysm may include:

• A pulsing sensation in the abdomen or neck
• Pain in the abdomen or back
• Nausea and vomiting
• Loss of consciousness

If you experience any of these symptoms it is important to seek medical attention right away. Treatment for aneurysms typically involves repairing the weakened artery wall with open surgery or an endovascular procedure. In some cases doctors may recommend lifestyle changes or medications to help reduce the risk of an aneurysm.
