Graves' disease is the most common cause of hyperthyroidism in children and adolescents. It most frequently occurs during adolescence and predominantly affects girls. In Graves' disease, the body produces antibodies to thyroid-stimulating hormone (TSH) receptors. These antibodies activate the receptors, causing excessive production of thyroid hormones and enlargement of the thyroid gland. The diagnosis is most often based on clinical presentation. The main symptoms in children and adolescents include пoiter (enlarged thyroid gland), rapid heartbeat, decreased academic performance and attention and concentration disorders. Modern highly sensitive tests for TSH receptor antibodies allow for accurate confirmation of the diagnosis. Treatment methods for Graves' disease include: Antithyroid drug therapy, surgical intervention amd radioiodine therapy (RAI). Choosing the appropriate treatment for Graves' disease in children is a complex process that requires an individualized approach and joint decision-making between physicians and parents.
