How does Type 1 diabetes primarily differ from Type 2 diabetes?

Type 1 diabetes is characterized by its autoimmune nature and typically presents in early childhood or adolescence, distinguishing it from Type 2 diabetes. In Type 1 diabetes, the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas, leading to an absolute deficiency of insulin. This condition often manifests suddenly and requires careful management through insulin therapy for life.

Unlike Type 1, Type 2 diabetes is usually associated with insulin resistance and has a slower onset, often developing later in life. It is more common in adults, although there has been an increase in cases among children and adolescents due to rising obesity rates and sedentary lifestyles. Additionally, while genetic factors can play a role in both types of diabetes, Type 1 is not strictly hereditary and has specific genetic markers associated with its autoimmune process.

The other options present misconceptions about the nature and severity of both types of diabetes, which provides clarity on why the correct statement highlights the distinct autoimmune and early-onset characteristics of Type 1 diabetes. This understanding is essential for recognizing the different management and treatment approaches necessary for each type.
