Metabolism is the general term for all chemical reactions in living cells, and it includes both material and energy metabolism. The metabolism of various organisms is different in the stages of growth, development and aging. Young infants and adolescents are in the process of growing their bodies and need more substances to build their own organisms, so their metabolism is vigorous and assimilation is dominant. In old age and later life, the body’s functions are degenerating and the metabolism is slowing down, so the relationship between anabolic and anabolic effects is transformed. The following points should be noted for the prevention of hyperthyroidism: 1) To regulate the mood and spirit Mental stimulation is a common cause of the disease, often aggravated by anxiety, emotional disturbance and nervousness. Therefore, patients with hyperthyroidism should pay attention to the regulation of their emotions and cultivate their moral character. They should not be angry when things happen, meditate and recuperate, often listen to elegant and beautiful music, and cultivate the habit of planting flowers, fish and birds, so as to enjoy their emotions and cultivate their moral character, and gradually eliminate their mental symptoms. Family members and colleagues should also sympathize and comfort, understand and care, and avoid direct conflicts. 2. Combination of work and rest During the onset of the disease, the patient should rest in bed appropriately. The resting environment should be quiet and the air should be circulated. Those who are mildly ill can get out of bed for light activities, to the extent that they do not feel fatigue, and should not overwork the household chores. When the disease is stable, should participate in some beneficial activities, work, to regulate the pleasure of life, but should not be overworked, and should not be long-term rest. 3, diet taboo tobacco and alcohol can prompt the patient excitement, agitation, and even irritability, heartbeat accelerated, will aggravate the disease, need to quit smoking and alcohol. Coffee, strong tea and other stimulating foods are forbidden to minimize the patient’s excessive excitement. The basal metabolic rate of hyperthyroidism increases and energy consumption increases, so a diet with high calories, high vitamins, sufficient protein and sugar starch should be the main food. Protein is generally not less than 1.5g per kg of body weight per day and should be mainly liver, fish, eggs, poultry and soy products. Eat more fresh vegetables and fruits, as well as milk, fish and shrimp with more calcium to supplement the calcium deficiency caused by hyperthyroidism. Try to eat less or no iodine-containing foods, such as seaweed and nori. Foods containing iodine are not conducive to the improvement of hyperthyroidism symptoms. 4, drink more tea and water Hyperthyroidism patients are prone to lack of water in their bodies due to accelerated basal metabolism and increased sweating, therefore, hyperthyroidism patients should drink more water, 1500-3000ml per day, to replenish the water lost due to excessive sweating. Excitement, agitation and other symptoms. 5.Rational pregnancy Generally speaking, there is no effect on pregnancy of hyperthyroidism patients, but we should consult endocrinologists and obstetricians and gynecologists to determine whether pregnancy is possible.
