Whether hyperthyroidism or hypothyroidism can work at night depends on the degree of hyperthyroidism or hypothyroidism, and it is necessary to consult a doctor to further see whether the night shift can be tolerated, as well as to consider the intensity of night shift work. If mild to moderate hyperthyroidism has no symptoms of cardiovascular system or over-excitement of the nervous system, the patient may be able to tolerate night work, but he should pay attention to the rest afterward, so as to avoid further aggravation of hyperthyroidism caused by the disruption of the endocrine system. However, in severe hyperthyroidism and hypothyroidism, if the nervous system is over-excited or inhibited, and there are symptoms of cardiovascular system, it is recommended not to work at night. To summarize, patients are advised to combine their own symptoms and go to the hospital for further examination.
