Type ___ diabetes usually starts in childhood and requires daily doses of insulin.

Type 1 diabetes is characterized by the body's inability to produce insulin due to the autoimmune destruction of insulin-producing beta cells in the pancreas. It often presents in childhood or early adulthood, hence its previous classification as juvenile diabetes. Individuals with Type 1 diabetes require daily insulin therapy to manage their blood glucose levels effectively, as their bodies are unable to produce this crucial hormone naturally. The dependency on external insulin is essential for survival and the management of blood sugar levels in these patients.

In contrast, Type 2 diabetes generally develops in adults and is often associated with insulin resistance, which means the body still produces insulin but does not use it effectively. Type 3 and Type 4 diabetes are not recognized classifications as commonly as Type 1 and Type 2, with Type 3 sometimes used to describe specific conditions related to diabetes, such as gestational diabetes or the effects of diabetes on the brain. Therefore, Type 1 diabetes is correctly linked to the need for daily insulin administration, starting typically in childhood.
