Why Is Smoking Bad for Brain Aneurysm?

Researchers say smoking may cause the brain's blood vessels to develop multiple aneurysms, or weak spots. These weak spots can rupture and cause bleeding that can lead to stroke, disability, and death. Doctors note that half the patients who suffer a ruptured aneurysm in their brain will die.

Can smoking make aneurysm worse?

Smoking also causes a temporary spike in blood pressure, which can weaken the arterial walls and make them more prone to form an aneurysm and rupture, Dr. Brown says.

What should you avoid if you have a brain aneurysm?

Stop smoking. Lower your blood pressure with diet and exercise. Limit your caffeine, because it can suddenly raise blood pressure. Avoid lifting heavy things; this also can raise your blood pressure.
