Type 1 Diabetes is which of the following?

Type 1 Diabetes is which of the following?

• A. Reversible disease
• B. Irreversible disease that typically starts in childhood and pancreas cannot make insulin
• C. Caused by poor diet
• D. Caused by overeating

Answer: (B)

Type 1 diabetes is an autoimmune process in which the body's immune system destroys the insulin-producing beta cells of the pancreas, leading to an absolute lack of insulin. This typically presents in childhood or adolescence and is not reversible—once the beta cells are gone, the pancreas cannot produce insulin, so lifelong insulin therapy is required. It is not caused by poor diet or overeating; those factors are more associated with Type 2 diabetes, which involves insulin resistance rather than complete insulin deficiency.
