Ouadie Rhabbouron

Some pains rightly worry us. But there's a word often shrouded in mystery: aneurysm. Behind this somewhat vague medical term lies a reality that's essential to understand better, not to panic, but to know when and how to react. Because in this kind of situation, information can truly make all the difference.

What exactly is an aneurysm?

Imagine a balloon forming on the wall of an artery: that's a bit like an aneurysm. It's a weakened area of ​​a blood vessel that dilates abnormally. If this dilation becomes too large, it risks rupturing and causing internal bleeding.   But not all aneurysms rupture   : some silent ones remain for a lifetime and never cause any problems.

What causes this fragility of the blood vessels?

Several factors can weaken the walls of our arteries over time. Here are the most common:

  • High blood pressure   : excessive pressure wears down the arteries and makes them more fragile.
  • Atherosclerosis   : the accumulation of fatty deposits in the vessels reduces their elasticity.
  • Genetics   : some people are more susceptible, although there is not always an obvious cause.
  • Infections or trauma   : inflammation or shock can weaken a localized area
