Type 1 diabetes is primarily caused by which of the following?

• A. A genetic mutation
• B. An autoimmune response
• C. Insulin resistance
• D. Obesity

Answer: (B)

Type 1 diabetes is primarily caused by an autoimmune response, where the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. This process typically leads to little or no insulin being produced, which is vital for regulating blood glucose levels. Unlike type 2 diabetes, where insulin resistance and factors such as obesity play significant roles, type 1 diabetes is primarily linked to this autoimmune mechanism. The onset is often during childhood or adolescence, though it can occur at any age and is not associated with lifestyle factors or obesity. Understanding this distinction is important as it informs management and treatment options for individuals with the condition.
