How to determine if it is hyperthyroidism

By symptoms, thyroid examination, laboratory tests and other aspects to determine whether hyperthyroidism. 1. Symptoms Hyperthyroidism patients usually appear irritability, sweating, hand shaking, palpitations, hyperappetite but weight loss, fatigue, insomnia and other symptoms. If these typical symptoms occur, especially when multiple symptoms exist at the same time, it is necessary to highly suspect the possibility of hyperthyroidism. For example, irritability, which is due to excessive thyroid hormone caused by increased nervous system excitability; hyperhidrosis is caused by hypermetabolism and increased heat production. 2. Thyroid examination mainly includes thyroid palpation and ultrasound examination. Palpation can find whether the thyroid gland is enlarged, texture and so on. Ultrasound can more clearly observe the size, shape and internal structure of the thyroid gland. If diffuse goiter is found, it can provide important clues for diagnosis. 3. Laboratory examination of thyroid function is the key basis for diagnosis of hyperthyroidism. If serum thyrotropin (TSH) level is reduced, and free triiodothyronine (FT3) and free thyroxine (FT4) levels are increased, hyperthyroidism can be diagnosed basically. This is because abnormal changes in thyroid hormone levels are a central feature of hyperthyroidism.
