Iron deficiency may increase stroke risk through sticky blood

Scientists at Imperial College London have discovered that iron deficiency may increase stroke risk by making the blood more sticky.

The findings, published in the journal PLOS ONE, could ultimately help with stroke prevention.

Every year, 15 million people worldwide suffer a stroke. Nearly six million die and another five million are left permanently disabled. The most common type, ischaemic stroke, occurs because the blood supply to the brain is interrupted by small clots.

The Imperial team found that iron deficiency increases the stickiness of small blood cells called platelets, which initiate blood clotting when they stick together. Although a link between iron deficiency and sticky platelets was first discovered almost 40 years ago, its role has been overlooked until now.
