Why Diabetes is Caused?

The cause of type 1 diabetes is unknown. Scientists understand type 1 diabetes causes the body to attack the cells that make insulin. Research is happening to understand why that is.

The cause of type 2 diabetes is a problem with the amount of insulin being made or used. The body can’t control its blood sugar levels so they keep rising. It’s often linked to:

being physically inactive
having excess weight or obesity
having a family history of type 2 diabetes
having pre-diabetes – when your blood sugar levels are above the normal range but not high enough to be diagnosed as diabetes.
It usually develops gradually and affects more adults over the age of 40. But it can develop at any age. And if you have a South Asian, African Caribbean or Black Asian background, you might have an increased risk of developing Type 2 diabetes.
