What happens in Diabetes?

We all rely on insulin, a hormone made in the pancreas, to move glucose from the blood into the body's cells.
When we eat, digestion of food breaks down carbohydrates into glucose that is absorbed into the blood in the small intestine.

If the insulin is working properly, then the glucose levels rise and fall normally, as insulin moves glucose into the cells to produce energy.

Insulin is the key that opens up the cell to allow glucose to enter.

People with diabetes have partial or complete lack of insulin production in the body. The key to open the cell is not working and so instead, glucose levels pile up in the bloodstream. The unused glucose circulates through the kidneys. When the amount of glucose is more than what the kidneys can handle, the extra glucose spills out into the urine.
