Stroke is serious. It is characterized by a brain damage caused by a shortage of blood flow to the brain. In order to function properly, the brain requires energy which is provided by oxygen. If blood flow is constrained, brain cells die which will lead to permanent brain damage. People who suffered stroke survive but with disability. You know how to prevent stroke.

The Health Promotion Board (HPB) is encouraging everyone to eat healthy and exercise regularly to reduce the risks of stroke and other chronic illnesses. It is up to you to heed the advice of HPB. You should know that there are two types of stroke – Ischemic and Hemorrhagic. Ischemic strokes refer to an impediment in the artery (carotid arteries).

The impediment develops by a process called thrombosis. Thrombosis is characterized by a development of clot inside the blood vessel. Ischemic stroke also develops when the clot travels which is called embolus. This type of stroke accounts for 80% of stroke cases. Hemorrhagic stroke on the other hand occurs when the blood vessels burst and bleed through the adjoining tissue. The blood can constrict the adjoining vessels thereby cutting the blood flow.

Hemorrhagic stroke accounts for 20% of stroke cases. This type of stroke is more severe than Ischemic because it can affect large areas of the brain and worse, it can lead to death. Your vulnerability to stroke should never be ignored. Prevention is better than cure so as early as now, lead a healthy life.
