Overview
Diabetes is a disease in which our bodies do not produce enough "Insulin" or effective insulin. Most of the components of our meal contain sugar. When we eat food, it is broken down into simple sugar called glucose. This glucose is taken by blood and it travels there freely till it is used by the cells to produce energy. Our cells use glucose to produce energy to work such as daily activities of walking, sitting, running etc. Apart from this, our body needs glucose for proper functioning of all organs like brain, heart, muscles, kidneys, lungs etc. However, insulin is required for the uptake of glucose by the cells. Without insulin our bodies are not able to use glucose effectively and our blood sugar levels increases. A gland in our bodies, known as, "Pancreas" produces exact amount of insulin, to breakdown the sugar produced in the body. A particular type of cells, known as, Beta Cells produce insulin in pancreas.

Type 1 Diabetes
Type 1 Diabetes is also known as Juvenile Onset Diabetes, it is a condition in which body fails to produce insulin. It occurs most often in childhood or in teens. Individuals with this type of diabetes need daily injections of insulin. They must balance their daily intake of food and activities carefully with their insulin shots to keep sugar levels under control. 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. 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. Almost 5 percent of the population suffers from juvenile diabetes.
