Which term best matches the following definition: Condition that results from excessive activity of the thyroid gland?

• A. Hyperthyroidism
• B. Hypothyroidism
• C. Epilepsy
• D. Myocardial Infarction

Answer: (A)

Excessive activity of the thyroid gland means it is overproducing thyroid hormones (T3 and T4), which speeds up the body's metabolism. This condition is called hyperthyroidism. People with hyperthyroidism often experience weight loss despite appetite, a rapid or irregular heartbeat, sweating, anxiety or nervousness, heat intolerance, and tremors, and the thyroid may become enlarged (a goiter). The other terms refer to different problems: hypothyroidism is when the thyroid is underactive, epilepsy involves seizures from brain activity, and a myocardial infarction is a heart attack caused by blocked blood flow to the heart.
