Diabetes is a condition where the amount of glucose (a type of sugar) in the blood is higher than normal because the body cannot store or use it effectively.

Glucose is a key source of energy for the body’s cells. When we eat food it is broken down to glucose. During digestion, glucose moves through the body via the bloodstream to feed the body cells where it is used as fuel for energy. The amount of glucose in the blood is controlled by a hormone called insulin, which is made by the pancreas (a small organ behind the stomach). Insulin helps glucose enter into the body cells. 

If our body is not making enough insulin or becomes resistant to insulin, it won’t be able to keep up with the amount of glucose in your bloodstream. This means that the glucose stays in the blood resulting in high glucose (or high sugar) levels in the blood. If this keeps happening over a period of time you will develop diabetes.
