An Overview On Hyperthyroidism

Hyperthyroidism is characterized by an overproduction and release of thyroid hormones from the thyroid gland. In contrast, thyrotoxicosis refers to the clinical symptoms arising from excessive circulating thyroid hormones, regardless of their source. Graves’ disease is the most common cause of hyperthyroidism, followed by toxic nodular goiter. Other significant causes of thyrotoxicosis include thyroiditis, iodine-induced or drug-induced thyroid dysfunction, and factitious ingestion of thyroid hormones. The treatment for hyperthyroidism typically Involves antithyroid drugs, radioactive iodine therapy, or surgery. However, antithyroid drugs are generally not used long-term in toxic nodular goiter due to a high recurrence rate of thyrotoxicosis. Beta-blockers are employed to manage the symptoms of thyrotoxicosis and may be the sole treatment required for conditions where thyroid hormones are not excessively produced or released. Thyroid storm, hyperthyroidism during pregnancy, and the postpartum period are special cases that necessitate careful evaluation and treatment.
