Hyperthyroidism patients have high basal metabolic rate because of high concentration of thyroxine. The food eaten is digested and metabolized quickly, so the weight does not increase but decreases; However, after taking antithyroid drugs, the basal metabolic rate returns to normal, and abnormal thinness will return to the original relatively "heavy" weight due to the recovery of metabolic rate. If you don't cooperate with diet control, you will definitely get fat. Some people mistakenly think that antithyroid drugs are steroids, which is a wrong concept; Or fear of obesity and dare not accept treatment is also very dangerous behavior, because severe hyperthyroidism may lead to thyroid storm and endanger life. Therefore, if you want to keep your figure from being deformed, you should eat properly and exercise regularly while treating hyperthyroidism. Generally, you can engage in isotonic aerobic exercise, such as swimming, indoor cycling or brisk walking, which can improve the cardiopulmonary function and achieve the effect of losing weight. Try to avoid holding your breath for equal length (such as lifting weights) and activities that are easy to cause sports injuries (such as jogging for obese people, which is easy to damage the knee joint). In addition, in the first two weeks after taking antithyroid drugs, some people may have a rash, which is usually not serious and temporary. Therefore, unless the situation worsens, there is no need to stop taking drugs. As for the product named "Nometine", it mainly acts on the satiety center of the hypothalamus of the brain, which can suppress appetite and produce satiety, thus achieving the effect of losing weight. But its side effects include: dry mouth, insomnia, palpitation, hypertension and other central autonomic nervous symptoms; Therefore, for patients with hyperthyroidism, the use of "Nometine" may aggravate the condition, so it is taboo.
