Type 1 diabetes causes the level of glucose (sugar) in your blood to become too high.
It happens when your body cannot produce a hormone called insulin, which controls blood glucose.
You need to take insulin every day to keep your blood glucose levels under control.
Managing type 1 diabetes can take time to get used to, but you can still do all the things you enjoy. This guide is here to help.
Type 1 diabetes is not linked with age or being overweight – these things are linked with type 2 diabetes.
