To give energy to cells, glucose must move from the blood into the cells. Insulin is what makes it happen.

Insulin works like a key opening a lock. It attaches to the cell and “opens the door” so glucose, also known as sugar, can enter the cell and be used for energy.

When insulin doesn’t open the cells, glucose can’t get in and provide them with energy. With all that glucose not getting into the cells, the result is LOT of glucose building up outside of the cells.
