Hyperthyroidism is a common endocrine disorder caused by an increase in metabolic rate due to excessive secretion of thyroxine by the thyroid gland. At present, the incidence of hyperthyroidism in men and women is 1:6. Patients with hyperthyroidism often show symptoms such as thinness, easy hunger, thick neck, rapid heartbeat, excessive sweating, hand trembling, etc. Some patients also have protruding eyes. Hyperthyroidism has a great impact on patients, causing insomnia and irritability, affecting daily life and interpersonal relationships: female patients may experience menstrual disorders and low menstrual flow, making it difficult to get pregnant, and even if they do get pregnant, there is a possibility of stillbirth. Severe hyperthyroidism can also lead to cardiovascular disease, liver dysfunction, muscle weakness, etc. The causes of hyperthyroidism are multifaceted. The main factors include: heredity, some cases have family clustering phenomenon, parents with hyperthyroidism, children are also prone to develop the disease; iodine intake, such as excessive iodine intake; emotional depression and long-term high pressure or stressful working and living environment are important triggers of hyperthyroidism. In hyperthyroidism, excessive secretion of thyroid hormones promotes the metabolism of fat, protein and other nutrients, and accelerates oxidation. The body’s heat production and heat dissipation increase significantly, and the basal metabolic rate increases abnormally, so the energy must be increased every day to correct the energy consumption in the body. For these reasons, the diet of hyperthyroid patients must pay attention to high calorie, high protein, high vitamin and supplementation of calcium, phosphorus and zinc to correct the consumption caused by hypermetabolism and improve the general condition. One, three high, one forbidden and one moderate: refers to high calorie, high protein, high vitamin diet, avoid iodine diet, moderate supplementation of potassium, calcium, magnesium, phosphorus, etc. (1) increase the supply of calories: sufficient carbohydrates should be given daily to correct overconsumption, and the daily energy supply should be 12540~14630 kJ (3000~3500 kcal), which is 50%~75% more than normal to meet the increased metabolic rate caused by excessive thyroxine secretion; (2) ensure protein supply: 15 grams of protein per kg of body weight should be supplied daily, but (3) pay attention to the supply of vitamins: it is appropriate to supply a rich supply of multivitamins, because high metabolism consumes energy and consumes a lot of enzymes, a variety of water-soluble vitamin deficiency, especially B vitamins, vitamin D is the main vitamin to ensure the absorption of calcium and phosphorus, should ensure the supply, while supplementing vitamin A and vitamin C; (4) appropriate calcium and phosphorus supply: in order to prevent osteoporosis, pathological fractures (5) Avoid iodine food and drugs: Iodine is the raw material for synthesizing thyroid hormone, if there is a large amount of iodine in the thyroid gland, thyroid hormone synthesis will be accelerated, thus iodine can induce hyperthyroidism and aggravate the symptoms of hyperthyroidism, so food containing iodine and iodine drugs should be avoided. All kinds of iodine-containing contrast agents should also be used with caution. (1) Food: According to the patient’s usual diet, various starchy foods such as rice, noodles, steamed bread, vermicelli, potatoes, pumpkin, etc.; various animal foods such as beef, pork, mutton, various freshwater fish, etc.; various fresh fruits and foods rich in calcium and phosphorus such as milk, nuts, fresh fish, etc. When the potassium is low, more oranges, apples, bananas, etc. can be chosen. (2) Avoid choosing foods: Avoid iodine-containing foods, such as seaweed, nori, hairy vegetables, iodized salt, etc. Chinese medicines such as seaweed, salvia, genistein, aromatic herbs, zhebei, etc. are also contraindicated. Iodized salt can be used after dry frying or exposure to the sun. (3) Pay attention to the sexual taste function of food. From the viewpoint of Chinese medicine, food selection has the effect of nourishing Yin, such as tortoise, turtle, water duck, etc., and less warm, spicy and stimulating food, such as rooster, etc. (4) It is recommended to consume a variety of fresh colored fruits and vegetables, such as carrots, celery, fungus, lily, mulberry, wolfberry, yam, gorgonzola, jujube, watermelon, orange, apple, etc. Alert: Stress is the trigger for hyperthyroidism! Don’t put too much pressure on yourself. Most of the hyperthyroidism patients who come to the clinic are energetic professional women who pursue perfection in everything and are dedicated to their work, such as employees of foreign companies, teachers, accountants, etc., as well as female high school students who are facing high school entrance exams. They are mostly around 25 years old. This is related to their endocrine activity and stability. When they are under great work and life stress, mental stimulation and other triggers, women are more likely than men to have abnormal autoimmune regulation, leading to hypermetabolic symptoms of excessive thyroid hormone secretion. Hyperthyroidism makes people sensitive and often, in the end, these strong women can’t go to work or take care of their families. In terms of mental state, they may suffer from insomnia due to excessive arousal, overreaction to external stimuli, and even personality changes. When these health crises occur in strong women, they should be examined by a hyperthyroid physician immediately and treated as soon as possible, otherwise they will easily age. In addition, once hyperthyroidism occurs, it is difficult to return to normal. The most important thing is to maintain a normal state of mind to prevent hyperthyroidism. Although hyperthyroidism has a certain genetic predisposition, it is only a predisposing factor, but the key lies in the psychological quality of individuals and their attitude towards the world, because bad emotions can affect appetite and sleep, or immune function and health. A good outlook on life is a good medicine for the prevention of hyperthyroidism. We should maintain an optimistic and open-minded attitude towards things around us, not to take the bull by the horns in the face of setbacks and failures, and to face life with a normal mind that is “unfazed by changes”. In addition, busy young people should try to maintain a relaxed work environment, maintain the harmony of family life, pay attention to the regularity of life, do not stay up late. Try to de-stress yourself, do more outdoor sports, play in the mountains, relax.
