Why is my blood glucose level high? How does this happen?

The process of digestion includes breaking down the food you eat into various different nutrient sources. When you eat carbohydrates (for example, bread, rice, pasta), your body breaks this down into sugar (glucose). When glucose is in your bloodstream, it needs help – a "key" – to get into its final destination where it's used, which is inside your body's cells (cells make up your body's tissues and organs). This help or "key" is insulin.

Insulin is a hormone made by your pancreas, an organ located behind your stomach. Your pancreas releases insulin into your bloodstream. Insulin acts as the “key” that unlocks the cell wall “door,” which allows glucose to enter your body’s cells. Glucose provides the “fuel” or energy tissues and organs need to properly function.

If you have diabetes:

• Your pancreas doesn’t make any insulin or enough insulin.

Or

• Your pancreas makes insulin but your body’s cells don’t respond to it and can’t use it as it normally should.

If glucose can’t get into your body’s cells, it stays in your bloodstream and your blood glucose level rises.
