6 Common causes of hyperthyroidism

Hyperthyroidism is a condition where the thyroid gland produces excessive thyroid hormones (T3 and T4), leading to symptoms such as weight loss, anxiety, rapid heartbeat, and heat intolerance. The main causes of hyperthyroidism include Graves’ disease, thyroid nodules, excessive iodine intake, thyroiditis, and overuse of thyroid medications. Understanding these root causes is crucial for proper diagnosis and treatment. Early detection helps prevent complications like atrial fibrillation, osteoporosis, and thyroid storm.

For patients managing hyperthyroidism, learning about dietary support, thyroid medications, and lifestyle changes can make a significant difference. Explore how conditions like Hashimoto’s thyroiditis (which may cause hypothyroidism or temporary hyperthyroidism) and thyroid nodules influence thyroid health.
