Iron deficiency may increase stroke risk by making the blood more sticky, scientists have discovered. 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. In the last few years, several studies have shown that iron deficiency, which affects around two billion people worldwide, may be a risk factor for ischaemic stroke in adults and in children.-link
Too much iron is bad, and too little is bad too. Biological enhancements will hopefully one day allow the body to store a large reserve safely, and eliminate easily excess. For now it's best to check iron levels and ensure excess and deficiency is avoided, as the present bodies are fragile.
