Alcohol and Strokes
Strokes happen when your brain is damaged by a blockage or bleeding in its blood vessels. Bleeding in the brain causes Haemorrhagic stroke, and Ischaemic stroke is caused by lack of blood from a blocked artery.

How is alcohol linked to stroke?
Alcohol is linked to strokes in a number of ways; firstly it can affect your blood pressure and heart, as well as affect clotting and bleeding in your blood vessels. Secondly less blood clotting can also increase the risk of bleeding in your brain, which can cause a Haemorrhagic stroke. More blood clotting could lead to a blocked artery, which is the cause of Ischaemic stroke.

Can drinking increase your risk of stroke?
If you’re a higher risk drinker, you’re more likely to suffer both types of stroke compared to non-drinkers. For increased risk drinkers, Haemorrhagic stroke is about one and a half times more likely for women and nearly twice as likely for men. Strokes are even more probable for higher risk drinkers: ranging from two to four times as likely. The risk of Ischaemic stroke also increases.
