Physical examination, laboratory tests, and ultrasonography are needed to check for hyperthyroidism. 1. Physical examination: eye movements can help diagnose Graves’ ophthalmopathy. Visual examination and palpation of the front of the neck can observe whether the thyroid gland is enlarged or not. Auscultation of the heart can help diagnose thyrotoxic heart disease. 2. Laboratory tests: thyroid stimulating hormone, thyroxine, triiodothyronine, etc. can clarify the presence of hyperthyroidism. Antithyroid antibody tests can help identify autoimmune thyroiditis by clarifying the presence of antibodies against thyroid tissue. 3. Ultrasonography: Thyroid ultrasound can observe the texture of the thyroid gland and the blood flow around it, as well as whether there are nodules in the thyroid gland. Patients with suspected hyperthyroidism are advised to go to the hospital in time for further examination and treatment as prescribed by the doctor after a clear diagnosis.
