Hyperthyroidism is a condition in which the thyroid makes more thyroid hormones than the body needs.

• A. Hypothyroidism
• B. Endocrinologist
• C. Hyperthyroidism
• D. Diabetes mellitus

Answer: (C)

Overproduction of thyroid hormones defines hyperthyroidism. The statement describes a condition where the thyroid makes more thyroid hormones than the body needs, which is exactly what hyperthyroidism means. So this term is the correct match. The opposite condition would be hypothyroidism, involving too little thyroid hormone. An endocrinologist is a physician who treats hormone problems, not a disease. Diabetes mellitus involves insulin and blood sugar regulation, not thyroid hormones. Understanding how the term aligns with the description clarifies the correct choice.
