The primary issue requiring management is that of the glucose cycle. In this, glucose in the bloodstream is made available to cells in the body; a process dependent upon the twin cycles of glucose entering the bloodstream, and insulin allowing appropriate uptake into the body cells. Both aspects can require management. Another issue that ties along with the glucose cycle is getting a balanced amount of the glucose to the major organs so they are not affected negatively.
Imagine our bodies to be a sugar bowl. A bowl of sugar. When we are young, our sugar bowl is empty. Over decades, we eat too much of the wrong things – sugary cereals, desserts and white bread. The sugar bowl gradually fills up with sugar until completely full. The next time you eat, sugar comes into the body, but the bowl is full, so it spills out into the blood.

Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas. This release of insulin promotes the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
