Fast facts about type 1 diabetes
What does glucose do in the body?
Short answer: The cells of your body use glucose for energy. The body gets glucose externally and internally: from food, and from stores in the liver and muscles. Glucose travels through your blood to the cells. To get into cells, glucose needs insulin.

When you eat, you take in energy from three different sources: carbohydrate, protein, and fat.
The foods you eat are broken down into glucose by your body. Glucose is a sugar or form of carbohydrate.
It is the sugar circulating in your bloodstream. It provides energy for movement and chemical reactions in the body.
The amount of glucose in your blood is called your blood glucose level. It is measured in milligrams per deciliter of mg/dl (in the U.S. and Germany) or as mmol/liter (in the U.K., Scandinavia, and Canada). You divide mg/dl by 18 to get mmol/liter.
To feel good and stay healthy, blood glucose should not be too low (hypoglycemia) or too high (hyperglycemia).
Glucose stimulates the pancreas to release insulin, if it is able to. In people with type one diabetes, there is no, or very little, insulin production, so it must be taken by injection or pump.
In people with type 1 diabetes who are not given insulin, blood glucose rises to high and dangerous levels.
