Most of the food people eat is turned directly into glucose when digested, and the body uses it as energy. The pancreas is responsible for making the hormone insulin which helps to get glucose into the cells of the body.
Diabetes is a long-term disease that occurs due to the pancreas not producing enough insulin or the body being unable to use the insulin it produces effectively.
The body is unable to process food properly to use for energy. Glucose builds up in the blood, which can lead to severe health problems.
There are two main types of diabetes. Type 1 diabetes is usually diagnosed in children and young adults and is also known as juvenile diabetes. With type 1 diabetes the body does not produce insulin.
