An abdominal aneurysm is a bulge or swelling in the wall of the abdominal aorta, the large blood vessel that carries blood from the heart to the lower body. This condition occurs when the artery weakens, leading to a risk of rupture, which can be life-threatening. Symptoms may include back pain or a pulsing sensation in the abdomen, but many people do not experience noticeable symptoms. Risk factors for developing an abdominal aneurysm include high blood pressure, smoking, and a family history of aneurysms. Regular check-ups and imaging tests, such as an ultrasound or CT scan, can help detect an aneurysm early. Treatment options may include monitoring or surgical intervention, depending on the size and growth rate of the aneurysm.
