What term describes long-term undiagnosed adult-onset hypothyroidism?

• A. Myxedema
• B. Hyperthyroidism
• C. Goiter
• D. Thyroid storm

Answer: (A)

Myxedema describes long-standing, undiagnosed adult-onset hypothyroidism. When thyroid hormone is chronically low, interstitial mucopolysaccharide deposits lead to nonpitting edema, especially in the face and tongue, along with fatigue, weight gain, cold intolerance, dry skin, and mental slowing. The term specifically captures the chronic hypothyroid state rather than acute or opposite conditions. Hyperthyroidism is the condition of excess thyroid hormone, producing symptoms like heat intolerance, weight loss, and rapid heart rate. Goiter simply means enlargement of the thyroid gland and can occur with various thyroid disorders, not necessarily chronic hypothyroidism. Thyroid storm is an acute, life-threatening surge of thyroid hormones, seen in severe hyperthyroidism, not chronic hypothyroidism.
