Stroke and brain damage

Diabetes can affect the brain and cause stroke

Stroke

Damage can occur in the brain with type 2 diabetes, mainly as a result of circulation problems.

 

There are a few reasons why the brain is vulnerable to stroke when a person has high blood pressure. One is that the arteries and smaller blood vessels in the brain are more brittle and can thus break open – the blood then spills out into the brain (brain haemorrhage) and parts of the brain die – that is, a stroke occurs.
A stroke can occur when damaged blood vessels allow blood to leak
The second way that a stroke can occur is through clots. These clots can break off or form in any part of the body and then travel in the blood stream into the brain where they will become stuck in a small blood vessel. This means that the part of the brain supplied by the blocked blood vessel dies – that is, a stroke occurs.
A stroke may occur when a clot travels to small blood vessel in the brain.

Did you know?

Myth: Eating too much sugar causes diabetes

Reality: This myth is false. Eating sugar is not the cause of the onset of diabetes. This disease is caused by a combination of genetic and environmental factors (such as diet). A diet high in fat and sugar may cause somebody to become overweight. Being overweight may increase the risk of type 2 diabetes. Anybody who has a family history of diabetes should eat a healthy and balanced diet and exercise regularly.
