Diabetes prevention

What is diabetes and how can we prevent it?

Diabetes is a long-term condition that causes a person's blood sugar level to become too high. There are two main types of diabetes – type 1 and type 2. Type 2 diabetes is far more common than type 1 diabetes, which is an autoimmune disease and cannot be prevented.  

In type 2 diabetes, the body either doesn't produce enough insulin to function properly, or the body's cells don't react to insulin. This leads to raised blood sugar levels that can lead to serious complications including stroke, heart and kidney disease, and amputations, if not well managed. 

There's lots of help and advice to help you reduce your risk of diabetes. And we can all reduce our risk of developing type 2 diabetes through maintaining a healthy weight, being active and eating a healthy diet.
