Healthy arteries are flexible, strong and elastic, said the Mayo Clinic.
The health site continued: “Their inner lining is smooth so that blood flows freely, supplying vital organs and tissues with nutrients and oxygen.
“Hypertension gradually increases the pressure of blood flowing through your arteries. As a result, you might have an aneurysm.
“Over time, the constant pressure of blood moving through a weakened artery can cause a section of its wall to enlarge and form a bulge (aneurysm).
“An aneurysm can potentially rupture and cause life-threatening internal bleeding.
“Aneurysms can form in any artery, but they’re most common in your body’s largest artery (aorta).”
