With the progress of society and the accelerated pace of life, the incidence of hyperthyroidism is getting higher and higher, and it is reported that the incidence of the disease in the population is about 0.2% to 0.3% per year, and the incidence of the disease in the female population can be up to 0.5%. The causes of hyperthyroidism are mainly immune disorders, endocrine disorders and neuropsychiatric factors, such as quarrels with others, and family members, coworkers, unpleasant, angry after the disease, or because of long-term mental trauma, mental stimulation (grief, anger, extreme panic, long-term too nervous, too worried) can be induced by hyperthyroidism, and in addition there are colds, tonsillitis, pneumonia, and other infections and all kinds of Trauma and overwork can also trigger hyperthyroidism. If you have hyperthyroidism and go to the hospital, people are used to go to the internal medicine department of endocrinology to find a doctor to treat it, or go to the surgery department to do surgical treatment, but do you know that you can go to the “nuclear medicine department” for treatment? Most of the patients may not know or even heard of the name of this department, in fact, hyperthyroidism in the Department of Nuclear Medicine treatment has better results. The treatment of hyperthyroidism with Iodine-131 is very simple, inexpensive and effective. Some people may see “nuclear”, a little talk about nuclear color change, fear of rays, in fact, in our lives there will be rays everywhere, cosmic radiation, environmental materials, drinking water and food have varying amounts of rays, to the hospital, fluoroscopy filming, CT, radiotherapy and so on is the use of rays, in fact, iodine-131 treatment of hyperthyroidism is not as large as a fluoroscopy of the rays. The amount of rays used in the treatment of hyperthyroidism is not as large as the amount of rays used in a fluoroscopy. In the United States and other economically developed countries, iodine-131 has been the most commonly used treatment of hyperthyroidism, in the United States about 80% of hyperthyroidism patients receive iodine-131 treatment, Europe about 43%. It is understandable that only 12% of the patients with hyperthyroidism in Japan, our eastern neighboring country, received iodine-131 treatment due to the fear of “nuclear rays” after the “atomic bomb” during the Second World War, but only 2% of the patients with hyperthyroidism in our country received iodine-131 treatment, which is a bit puzzling. But only 2% of hyperthyroid patients in our country receive iodine-131 treatment is a bit puzzling. There is only one explanation for this, and that is a lack of understanding of nuclear medicine, and a lack of understanding or little knowledge of nuclear radiation. Iodine-131 treatment of hyperthyroidism has gone through more than half a century of course, since 1942 after more than half a century of extensive clinical practice and long-term follow-up surveys have proved that iodine-131 is a safe and effective radiopharmaceutical for the treatment of hyperthyroidism. Within the therapeutic dose range, there are no other significant adverse reactions. At present, more and more doctors and patients are willing to accept iodine-131 treatment, foreign dignitaries such as former U.S. President George W. Bush, former Japanese Prime Minister Kakuei Tanaka, who suffered from hyperthyroidism, were diagnosed with iodine-131 treatment by medical experts. Iodine-131 treatment for hyperthyroidism is simple, safe and effective, suitable for all age groups, with a short cure time, low cost and very few relapses. Patients usually only take the medicine once, two weeks after the hyperthyroidism symptoms began to ease, hyperthyroidism symptoms, the more serious, the more obvious improvement in symptoms, when the patient’s enlarged thyroid gland began to retract, weight gain, three months after the recovery of the hyperthyroidism effective rate of more than 95%, the cure of hyperthyroidism recurrence rate is very low, only a few patients line second treatment, a very small number of patients need multiple treatments. Compared with the internal medicine treatment, it is very convenient, eliminating the trouble of long-term medication and regular checking of T3, T4, TSH, liver function and blood routine. Drug treatment generally requires long-term medication, the course of treatment at least 2 to 3 years, the cure rate is less than 40%, about 50 to 60% of patients relapse after stopping the drug. In addition, medication has many side effects. For example, it has an effect on the liver, and some patients will suffer from liver function damage or even cirrhosis after taking antithyroid drugs such as tapazole, and it has an effect on blood cells, which can cause the blood cells to drop to a very low level and jeopardize the life of patients, and some patients will suffer from allergies, and so on. Drug therapy must be checked once a month T3, T4, TSH, liver function, blood routine in order to adjust the dose of antithyroid drugs, such as drug dosage is too large will lead to hypothyroidism, insufficient dosage of hyperthyroidism symptoms can not be controlled, hyperthyroidism for a long time control is not good, it will lead to hyperthyroidism heart disease, cardiac enlargement, atrial fibrillation, heart failure, the age of people caused by osteoporosis, peripheral pain, so the drug treatment is more complicated. Iodine-131 treatment has almost no side effects. The Iodine-131 Treatment of Hyperthyroidism Collaborative Group, which consists of 23 hospitals in the United Kingdom and the United States, has conducted research on a large number of patients for 47 years and found that: Iodine-131 treatment is very safe, and it will not cause any discomfort or other side effects within the therapeutic dosage, and even if it does, they are also very mild. At the same time, Iodine-131 treatment can rapidly control hyperthyroidism symptoms and improve the quality of life of patients. 1998 American scholars refer to 160 literature review, hyperthyroidism, especially children’s hyperthyroidism treatment, comparing the advantages and disadvantages of drugs, surgery and Iodine-131 treatment, especially emphasizing the safety and effectiveness of Iodine-131 treatment of children’s hyperthyroidism, and they pointed out that, after a few years of antithyroid medication remission rate of 50-60%, generally less than 30-45%, and the rate of remission of 30-45%, and the rate of remission of 30-45%. They pointed out that the remission rate of antithyroid drugs after several years is at most 50-60%, generally less than 30-45%, and the remission rate of adolescent hyperthyroidism is 30%. While the remission rate of children is 17%, the common side effects of the drug are more, such as liver function impairment 28%, leukopenia 25%, rash 9%, 1/3-1/4 patients can not tolerate the drug and stop the drug. Some serious side effects such as acute hepatic necrosis, granulocyte deficiency can be fatal, and aplastic anemia can also occur. Subtotal thyroidectomy for hyperthyroidism has a high remission rate of up to 80%. Symptoms and signs of hyperthyroidism rapidly improve after surgery, and the recurrence rate of hyperthyroidism is about 10%. However, hyperthyroidism surgery is dangerous, expensive and has many side effects. Surgery for hyperthyroidism is an unwise choice. 1998, the American scholar David Cooper wrote that “in the near future, the commonly used partial thyroidectomy will become history”. Some patients are worried that iodine-131 treatment of hyperthyroidism will have more side effects. Swedish scholars of more than 40,000 routine iodine-131 treatment of hyperthyroidism patients for 38 years of clinical research, found that iodine-131 treatment of hyperthyroidism, whether in the near future or in the long term are no significant side effects. In the past, people were worried that Iodine-131 treatment of hyperthyroidism would affect fertility, whether it could cause cancer, lead to hypothyroidism, etc. After long-term clinical research by scholars in Europe and the United States, the following conclusion was reached: Iodine-131 will not affect the fertility of patients, on the contrary, the drug treatment will affect the development of the fetus. Therefore, experts suggest that women of childbearing age with hyperthyroidism should use iodine-131 treatment as early as possible for the purpose of eugenics. Iodine-131 treatment of hyperthyroidism will not lead to an increase in the incidence of cancer, on the contrary, the incidence of oral cancer, brain tumors, lung cancer in patients with hyperthyroidism treated with medication is 5% higher than that in the normal population and the group treated with iodine-131, so in a sense, iodine-131 treatment of hyperthyroidism is safer than the drug treatment. Regarding hypothyroidism, European and American scholars have pointed out that it is not unique to iodine-131 treatment of hyperthyroidism, but also occurs in drug and surgical treatments, and its incidence is not different from that of iodine-131 treatment, indicating that hypothyroidism is not related to iodine-131 treatment. Studies have shown that hyperthyroidism and hypothyroidism may be different processes of the same disease, with hyperthyroidism progressing to hypothyroidism. Studies have also shown that about 70% of patients with hyperthyroidism will become hypothyroid if they are observed long enough. Regardless of the method of treatment of hyperthyroidism, as long as the cure of hyperthyroidism, hypothyroidism may occur, its incidence of about 2 to 5%, with the use of which method has nothing to do. Therefore, European and American scholars believe that hypothyroidism is not a complication of iodine-131 treatment. At present, our scholars also gradually recognize this point, the iodine-131 treatment of hyperthyroidism is no longer restricted, that hyperthyroidism iodine-131 treatment is the preferred method of treatment. European and American scholars believe that: since hypothyroidism is not a complication of iodine-131 treatment, in order to rapidly control the symptoms of hyperthyroidism, improve the quality of life of patients, can be applied to high-dose iodine-131 treatment of hyperthyroidism, even if hypothyroidism, hypothyroidism is good to find a good treatment, oral thyroxine treatment without toxic side effects, and the patient’s symptoms of hyperthyroidism rapidly improve the quality of life has been significantly improved, weighing the pros and cons of iodine-131 treatment should be treated as the preferred treatment method. The preferred treatment method. Most of the scholars in China are more cautious to implement “personalized” treatment for hyperthyroidism patients, which is different from person to person, with small dosage, and the rate of hypothyroidism is very small. The world’s authoritative medical tome, “Xie’s Internal Medicine” 1995 edition in the discussion of iodine-131 treatment of hyperthyroidism concluded that: “due to the safety and effectiveness of iodine-131 treatment, it is the most effective treatment of hyperthyroidism, in many internal medicine, only iodine-131 treatment of hyperthyroidism can be said with certainty that it is completely cured without any obvious side effects, is the most cost-effective treatment method today. the treatment with the highest cost-effectiveness ratio.” The world’s most influential medical journal “American Journal of Medicine” pointed out that: “In the United States, iodine-131 has been the most commonly used method of hyperthyroidism treatment, the method will not cause cancer, will not reduce the patient’s fertility, pregnancy before treatment with iodine-131 has no adverse effects on the offspring.” China’s application of iodine-131 treatment of hyperthyroidism began in 1956, a hospital with iodine-131 treatment of hyperthyroidism began in 1980, after more than 20 years of unremitting efforts of nuclear medicine workers, more and more doctors and patients choose to use iodine-131 treatment of hyperthyroidism, and has now cured thousands of hyperthyroid patients. Therefore, after getting hyperthyroidism, the first thing you should choose is: Iodine-131 treatment.
