Diabetes is a lifelong condition that causes a person’s blood sugar level to become too high.

There are 2 main types of diabetes:

  • Type 1 diabetes – where the body’s immune system attacks and destroys the cells that produce insulin 
  • Type 2 diabetes – where the body doesn’t produce enough insulin, or the body’s cells don’t react to insulin
