International health insurance customers might want to discuss stroke risks in more detail with their doctor following a recent study.
Conducted by a Dutch team, the project found eight main triggers that seem to increase the risk of an intracranial aneurysm.
Published in Stroke: Journal of the American Heart Association, the report confirmed that drinking coffee can temporarily increase the risk of an aneurysm by 10.6 per cent.
If this occurs, the weakness in the wall of the brain's blood vessel can cause it to balloon. A rupturing of the blood vessel and a stroke can follow.
Vigorous physical exercise, nose blowing sexual intercourse and being angry are also risk factors.
Monique Vlak, lead author of the research, commented: "All of the triggers induce a sudden and short increase in blood pressure, which seems a possible common cause for aneurismal rupture.
"Subarachnoid haemorrhage caused by the rupture of an intracranial aneurysm is a devastating event that often affects young adults."
