The risk of stroke is two and a half times higher in people with diabetes. A stroke is a damage to part of the brain tissue as a result of a loss of blood and oxygen. Brain tissue needs a constant supply of oxygen and nutrients to keep nerve cells and other parts of the tissue alive and functioning. The brain cannot store oxygen, so it relies on a network of blood vessels to provide it with blood that is rich in oxygen.
A stroke occurs when one of these blood vessels becomes damaged or blocked, preventing blood from reaching a part of the brain tissue. When the tissue is cut off from its supply of oxygen for more than 3 - 4 minutes, it begins to die.
A stroke is a medical emergency. If you experience any of the major stroke warning signs listed below, call 999. You must get to the hospital immediately.
