Type 1 diabetes causes the level of glucose (sugar) in your blood to become too high.
It happens when your body can't produce enough of a hormone called insulin, which controls blood glucose.
You need daily injections of insulin 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.
Symptoms and getting diagnosed
See your GP if you have symptoms of type 1 diabetes:
feeling very thirsty
peeing more than usual, particularly at night
feeling very tired
losing weight without trying
thrush that keeps coming back
blurred vision
cuts and grazes that aren't healing
Type 1 diabetes symptoms can come on quickly, particularly in children.
