Hyperthyroidism is short for hyperthyroidism. It is caused by the body’s thyroid gland producing too much thyroid hormone. Most patients start the disease slowly and gradually feel unwell before going to the doctor. Its clinical manifestations are varied, and its main symptoms include: panic, heartburn, irregular heart rate, excessive sweating, weakness, loss of weight, polyphagia, insomnia, agitation, talkativeness, trembling of hands, increased frequency of bowel movements, thickening of the neck, protruding of the eyeballs outward, and in some cases, low-potassium paralysis, irregular menstruation in females, impotence in males, etc. These symptoms do not occur in every patient, and they are not always recognized. These symptoms do not manifest in every patient at the same time, and most patients show some of these symptoms predominantly, and other symptoms are not very typical. The diagnosis of hyperthyroidism patients generally need to make the following tests: 1, blood test FT3, FT4, TSH, blood routine, etc., if possible, can be tested for TRAb, TPOAb; 2, thyroid iodine absorption rate test; 3, if necessary, need to be made of thyroid ultrasound or isotope scanning (ECT) and other tests. As the causes of hyperthyroidism are more, clinical typing is more, and the clinical manifestations are also diverse, generally in the primary hospitals do not have the necessary instrumentation, coupled with the lack of systematic understanding of this disease, so misdiagnosis, misdiagnosis and treatment occurs from time to time. It is often misdiagnosed with coronary heart disease, colitis, periodic paralysis, hysteria or psychosis, menstrual irregularities or infertility. In the clinical diagnosis of the disease is not difficult, as long as the conditions of the regular hospital by a specialist doctor’s examination is very easy to diagnose. In the diagnosis and treatment of hyperthyroidism, do not only rely on the results of laboratory tests to make a diagnostic conclusion, do not only look at the laboratory tests of FT3, FT4 a high diagnosis of hyperthyroidism, should be out of the diagnosis of this misunderstanding. Doctors should perform the necessary palpation and auscultation of the thyroid gland to see if the thyroid gland is enlarged? Is it soft or hard? Are there nodules? Whether there is a vascular murmur and so on, and then a comprehensive analysis, only to distinguish between different types, in order to be suitable for the treatment of the disease, and the effect of treatment is not the same. This is the patient often ask a question, “Why some patients treatment for a few months on the good, and some patients treatment for several years is not good? One of the main reasons. It is because of the different types of the disease. Generally commonly referred to as hyperthyroidism is diffuse goiter with hyperthyroidism (i.e. Graves’ disease) and is one of the more persistent types. It is often necessary to distinguish from the following types of hyperthyroidism: 1, subacute thyroiditis with hyperthyroidism; 2, chronic lymphatic thyroiditis (i.e., Hashimoto’s thyroiditis) with hyperthyroidism; 3, nodular goiter with hyperthyroidism; 4, high-functioning adenomas with hyperthyroidism; 5, thyroid cancer with hyperthyroidism; and so on and so forth, as well as many other diseases accompanied by hyperthyroidism. Only by identifying the type of hyperthyroidism can a specific treatment plan be developed.
