When food is digested, they are turned to glucose and enter the bloodstream. Then they go to the cells which need energy. However, these glucose need special keys called insulin produced by beta cells to enter the cells. The exact cause of juvenile diabetes is still unclear, but scientists believe that the main cause is either caused by toxins or genetic mutation which changes the body’s immune system. Normal immune system is only supposed attack the germs which enter the body. But mutated immune system mistakes beta cells for harmful cells from outside and starts attacking them. Therefore, the beta cells die out and there aren’t enough beta cells to make enough insulin. So the glucose can’t go into the cells and they stay in the bloodstream. Glucose level then rise high in bloodstream and this is the juvenile diabetes. High fat or high sugar diet is another factor for this disease. Also, people who have ancestors who had juvenile diabetes are more likely to have this disease than other people.
