Diabetes (type 1) is a disease in which the body does not make insulin.

• A. Diabetes (type 1)
• B. Diabetes mellitus
• C. Hyperthyroidism
• D. Endocrinologist

Answer: (A)

Type 1 diabetes is defined by autoimmune destruction of pancreatic beta cells, leading to little or no insulin production. The statement describes this form specifically, making it the best match. Diabetes mellitus is a broader category that includes both Type 1 and Type 2; not all diabetes results from a complete lack of insulin—Type 2 often has insulin resistance with some insulin production. Hyperthyroidism is a thyroid condition unrelated to insulin, and an endocrinologist is a physician who treats hormone disorders, not a disease. In Type 1, insulin replacement is essential because the body cannot produce it adequately.
