What characterizes type 1 diabetes?

Type 1 diabetes is characterized by the pancreas producing little or no insulin due to autoimmune destruction of the insulin-producing beta cells in the islets of Langerhans. This lack of insulin production leads to an inability to regulate blood glucose levels effectively, resulting in hyperglycemia. Unlike type 2 diabetes, where insulin resistance is a significant factor, type 1 diabetes requires insulin therapy for management and typically presents in childhood or adolescence.

In contrast, conditions like type 2 diabetes are associated with insulin resistance, where the body does not respond properly to insulin, often linked to overweight or obesity in patients. Understanding the specific nature of type 1 diabetes is essential for recognizing its management requirements and differentiating it from other forms of diabetes.
