Detailed explanation-1: -When thyroxine is secreted in lower concentration by the thyroid gland, it leads to a condition called goitre. In goitre, the thyroid gland swells up and a lump appears at the front of the neck.
Detailed explanation-2: -Hyperthyroidism happens when the thyroid gland makes too much thyroid hormone. This condition also is called overactive thyroid. Hyperthyroidism speeds up the body’s metabolism. That can cause many symptoms, such as weight loss, hand tremors, and rapid or irregular heartbeat.
Detailed explanation-3: -Hypothyroidism, caused by an underactive thyroid gland, typically manifests as bradycardia, cold intolerance, constipation, fatigue, and weight gain. In contrast, hyperthyroidism caused by increased thyroid gland function manifests as weight loss, heat intolerance, diarrhea, fine tremor, and muscle weakness.
Detailed explanation-4: -So the correct answer is cretinism.
