Hyperthyroidism is a condition where the thyroid gland produces too much thyroid hormone, speeding up the body's metabolism. In children, this can lead to symptoms such as rapid heart rate, weight loss despite a good appetite, irritability, excessive sweating, and difficulty sleeping. If left untreated, hyperthyroidism can lead to more serious complications like growth issues, bone loss, and heart problems. Treatment typically involves antithyroid medications to reduce hormone production, radioactive iodine therapy, or in rare cases, surgery. The benefits of treatment include better hormone regulation, improved growth, and alleviation of symptoms. The duration of treatment can vary, with medications often required for months or even years, while radioactive iodine therapy can provide long-term results.
