Graves’ hyperthyroidism is the most common form of hyperthyroidism, accounting for about 85% of cases.The cause of hyperthyroidism in Graves’ disease is unclear, and it may be due to a variety of factors such as genetics, infections, immunity, etc., which lead to the production of anti-TSH receptor antibodies (TRAb) and excessive synthesis of thyroid hormones, exceeding the storage capacity of the thyroid follicles, and then “overflowing “overflow” into the blood, the level of thyroid hormone in the blood rises and leads to hyperthyroidism. Other disorders in which excessive hormone production causes hyperthyroidism include toxic multinodular goiter, autonomous high-functioning adenoma of the thyroid gland, and pituitary hyperthyroidism. After diagnosis of Graves’ hyperthyroidism, in addition to drug treatment, daily lifestyle and diet also play a vital role in the regression of the disease, therefore, we will Graves’ disease hyperthyroidism patient’s precautions are summarized in the following four points: 1, absolutely avoid iodine Iodine is the main raw material for the manufacture of thyroid hormones, excessive iodine intake can lead to the aggravation of the condition of hyperthyroidism or delayed recovery. We should do: 1, avoid eating all seafood, try to eat non-iodized salt. Normal people’s daily iodine intake is 150 micrograms/day, while hyperthyroid patients should be less than 50 micrograms/day. We categorize iodine-containing foods into three classes. The first class contains thousands to tens of thousands of micrograms of iodine per 100 grams or more, including: kelp, nori, moss strips, jellyfish, etc. The second class contains hundreds to thousands of micrograms of iodine per 100 grams or more, including: sea crabs, shellfish in the sea, etc. The third category contains tens to hundreds of micrograms of iodine per 100 grams or more, including: marine fish, marine shrimp, etc.; and iodized salt iodine content per gram of salt generally contains about 20-30 micrograms. Therefore, all seafood relative to hyperthyroidism patients are high iodine food, iodized salt should also try to avoid. Reduce the chance of eating out. Salt used in restaurants is usually iodized salt, and the same frying pan, we can’t guarantee that the last guest order is not seafood, in the cooking process there is inevitably a large amount of iodine mixed into the food. Avoid using iodine-containing medicines and cosmetics. Medicines include: anti-arrhythmic drug amiodarone, contrast medium for CT enhancement, iodine for disinfection, iodine-containing vitamin tablets; cosmetics include: seaweed-containing facial cleanser, shampoo, face mask, foot bath powder, etc. 4, avoid traveling to coastal cities. In short, in life, eat, use, play should try to pay attention to avoid excessive intake of iodine, to achieve “absolute avoidance of iodine”. In the diet of hyperthyroidism patients should also pay attention to: 1, stimulating food (such as: spicy food, coffee, strong tea, etc.): hyperthyroidism patients themselves can have panic, fear of heat, mental excitement, insomnia and other sympathetic excitation symptoms, stimulating food can lead to the aggravation of the above symptoms, should be avoided before the complete control of the function of the thyroid gland. In addition, some cold medicines, such as Tylenol, Bactrim, etc., the instructions are written on the “hyperthyroidism patients with caution”, that is because these drugs contain pseudoephedrine, which can lead to accelerated heart rate, can be taken after control. 2, calcium: high metabolism is one of the characteristics of hyperthyroidism, therefore, with osteoporosis of middle-aged and elderly patients should pay attention to supplemental calcium and vitamin D. 3, vitamins: hyperthyroidism is very easy to cause vitamin deficiencies, coupled with hyperthyroidism itself as well as hyperthyroidism in the treatment of the application of anti-thyroid medication, resulting in a decrease in white blood cells, but also need to increase the vitamin supplement. Second, avoid infection, the total number of white blood cells and granulocytes of hyperthyroid patients are low, which can easily lead to infection. If infection occurs, it will make the controlled hyperthyroidism relapse or aggravate, and even hyperthyroidism crisis. Studies have shown that infections can elevate TRAb, leading to a prolonged course of hyperthyroidism. Therefore, we should learn to prevent all kinds of infections, and once the signs of infection are found, they should be treated early, and it is not recommended to rely on their own resistance to fight. Third, pay attention to rest, hyperthyroidism patients should not often stay up late and long-distance running, swimming, climbing and other strenuous activities; the condition of the heavy, it is advisable to rest, or even bed rest. In addition, because some hyperthyroidism patients can be accompanied by protruding eyes, so that the extraocular muscles are paralyzed, easy to visual fatigue, eyeball swelling. After reading books and newspapers for a long time, especially after watching TV, the eyeballs often feel swollen and painful, so patients with this disease should pay attention to reducing eye irritation and visual fatigue. Fourth, follow the doctor’s prescription medication At present, anti-thyroid drugs are still the basic treatment of Graves’ hyperthyroidism, which does not destroy the structure of the thyroid follicle, safe and effective, the drug effect is reversible, will not cause permanent hypothyroidism. However, drug treatment is a long-term process, the average treatment time is two years, especially in the first six months of the onset of the disease need to be followed up regularly to adjust the drug dose, and some of the patients may have liver function damage and white blood cell decline, so in the early stage of the onset of hyperthyroidism need to be diligent to check the blood routine, liver function to understand the side effects of drugs. This requires the full cooperation of the patient to achieve regular treatment, follow the doctor’s instructions to take medication, in order to achieve the expected therapeutic effect.
