Type 1 vs Type 2 Diabetes in details

Type 1 Diabetes usually appears first in children and adolescents, but it can also occur in adults. In type 1 diabetes the immune system attacks pancreatic beta cells so that they can no longer produce insulin.

Type 2 Diabetes is more likely to appear as people age, but children may still develop it. In this type, the pancreas produces insulin, but the body cannot use it effectively. Lifestyle factors appear to play a role in its development.
