Some patients feel dizziness after surgery for smoky brain disease because the disturbance of blood flow to the brain after cranial surgery may cause dizziness, and some patients even experience vertigo, which is normal in the early stage. If dizziness occurs repeatedly one month after discharge from the hospital and stabilization, it is an abnormal situation. It is necessary to go to the hospital to see a doctor further to determine whether it is due to the surgery or a new situation after the surgery, and to treat according to the specific cause of the disease. Dizziness does not occur after surgery for smog disease. It may be caused by long bed rest time in the early period after surgery, going down to the ground after going home, and change of body position, which leads to abnormal cerebral blood flow and blood pressure, and causes dizziness. Often there is no persistent dizziness, and the patient can gradually get out of bed for exercise, dietary supplements, etc., which can significantly improve dizziness. If frequent dizziness occurs at a later stage, it is an abnormal situation and needs to go to the hospital for diagnosis and treatment.
