If the high blood glucose after surgery is a transient elevation caused by the body’s stress response, no treatment is usually required. If it is due to complications of various infections, general measures as well as medication are required. 1. If the post-surgery blood glucose increase is caused by the body’s stress reaction, for example, when the body is overly tense during the surgery, or during general anesthesia, fatigue and other stresses, the body will produce growth hormone, adrenaline and other hormones that fight against insulin, which will promote the decomposition of glycogen, and the post-surgery blood glucose transiently rises. In this case, there is no need for treatment, and the blood glucose will return to normal after a period of appropriate rest. 2. If the high blood glucose after surgery is caused by various infections, patients need to apply antibiotics according to the doctor’s prescription, remove the triggers of elevated blood glucose, adjust the dietary structure, and exercise appropriately. When the situation of elevated blood glucose occurs after surgery, it is necessary to complete the relevant examinations to clarify the specific causes, and cooperate with the doctor to actively treat.
