What condition is caused by a deficiency of thyroid hormone in adults?

• A. Hyperthyroidism
• B. Myxedema
• C. Hypoparathyroidism
• D. Hashimoto's disease

Answer: (B)

Myxedema is a condition that results from a significant deficiency of thyroid hormone in adults, often due to an underactive thyroid, also known as hypothyroidism. This deficiency can lead to a range of symptoms, including fatigue, weight gain, cold intolerance, and depression. Myxedema specifically refers to the severe form of hypothyroidism, where the body experiences a slowing down of metabolic processes. It can also cause alterations in the skin, creating a characteristic swelling or thickening, particularly noticeable around the eyes and lower legs. This condition emphasizes the critical role that thyroid hormones play in regulating metabolism and overall health. In contrast, hyperthyroidism leads to an excess of thyroid hormone, resulting in symptoms such as weight loss and increased heart rate. Hypoparathyroidism relates to the parathyroid glands and calcium levels, while Hashimoto's disease is an autoimmune disorder characterized by the thyroid being attacked by the body’s immune system, which can lead to hypothyroidism, but is not itself a direct deficiency of thyroid hormone in adults.
