Final answer:
Type 1 diabetes generally develops before reaching puberty and is an autoimmune disorder that commonly manifests during childhood.
Step-by-step explanation:
Most type 1 diabetics develop the condition before reaching puberty. Type 1 diabetes is an autoimmune disorder where the individual's immune system attacks the insulin-producing beta cells in the pancreas. It commonly manifests in childhood or adolescence, and unlike type 2 diabetes, it is not typically associated with lifestyle factors such as diet or obesity. Instead, the disease develops as a result of an immune response, possibly triggered by genetic predispositions or environmental factors like viral infections.
