Final answer:
Hyperthyroidism is characterized by symptoms such as rapid heartbeat, heat intolerance, and goiter, caused by excessive thyroid hormone production. Treatment typically involves medication to balance hormone levels or, in severe cases, removal of the thyroid gland.
Step-by-step explanation:
The Symptoms and Treatment of Hyperthyroidism
The symptoms described, including rapid and irregular heartbeat, heat intolerance, weight loss, goiter, exophthalmos, feeling too hot all the time, along with anxiety and nervousness, are indicative of an overactive thyroid condition known as hyperthyroidism. The thyroid gland, located in the neck, plays a crucial role in the regulation of growth, metabolism, and appetite by producing thyroid hormones. When it releases too much thyroxine, symptoms of hyperthyroidism or Grave's disease such as agitation, bulging eyes, and weight loss occur.
Treatment for hyperthyroidism often includes medications that restore hormonal balance. Anti-thyroid drugs, for instance, can reduce the production of thyroid hormones. In severe cases where medication is not effective, the thyroid gland might be partially or entirely removed surgically, or through the administration of radioactive iodine, which leads to hypothyroidism and requires ongoing management.
