Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin, a hormone needed to allow sugar (glucose) to enter cells to produce energy. The far more common type 2 diabetes occurs when the body becomes resistant to the effects of insulin or doesn't make enough insulin.
Various factors may contribute to type 1 diabetes, including genetics and exposure to certain viruses. Although type 1 diabetes typically appears during childhood or adolescence, it also can develop in adults.
Despite active research, type 1 diabetes has no cure, although it can be managed. With proper treatment, people who have type 1 diabetes can expect to live longer, healthier lives than they did in the past.
