If diabetic patients’ blood glucose reaches a stable state and there is no corresponding complication, they are generally allowed to work night shifts if the intensity of night shifts is not too high, but if their blood glucose fluctuates greatly, it is generally not recommended to work night shifts. If the diabetic patient’s blood glucose control is stable, such as fasting blood glucose <7.0mmol/L, two-hour postprandial blood glucose <10.0mmol/L, it is generally possible to work night shift. If the blood glucose control is not up to standard, or the blood glucose fluctuation is relatively large, it is not recommended to work night shifts. This is because night shift will increase the secretion of adrenocorticotropic hormone, which is a stronger glucose-raising hormone, and will easily lead to fluctuations in blood glucose. In order to avoid further increase in blood sugar, it is recommended not to work night shifts. During night shifts, diabetic patients also need to pay attention to observing the changes in blood sugar, during which they need to strictly follow the doctor's instructions.
