Juvenile diabetes is an autoimmune disorder which can be due to environmental trigger or virus, which hampers the function of beta cell. Once the beta cells are destroyed the body is unable to produce insulin. It is also believed that Type 1 diabetes results from an infectious or toxic insult to a child, whose immune system is predisposed to develop an aggressive autoimmune response either against molecules of the B cell or against altered pancreatic B antigens, resembling a viral protein. A child with diabetic siblings is more prone to develop juvenile diabetes than the child from a totally unaffected family. It is considered to be a more hereditary problem than excess eating or being obese.
Pancreas produces the exact amount of insulin, to breakdown the sugar produced in the body. The juvenile diabetic lack the production of insulin so, sugar builds up high in the blood, overflows into the urine and passes from the body unused.
It is estimated that about 10-15% in United States are suffering with juvenile diabetes. Approximately 35 American children are diagnosed with juvenile diabetes every day.
