Surgery for fracture patients may affect blood glucose. Trauma can cause fractures, and after trauma, the body will produce a stress response, which will regulate some hormones in the body, resulting in an increase in blood glucose, which is usually able to return to normal levels after timely treatment. In addition, major surgery is also a stressful situation, which may also cause elevated blood glucose. Therefore, surgery for fracture patients may affect blood glucose. Fracture patients who need to undergo surgery can have their blood glucose monitored before, during and after surgery to help detect any abnormalities in blood glucose. It is recommended to inform the doctor in case of blood sugar abnormalities and ask him/her to take care of it.
