Dizziness after hypertensive surgery may be related to the effect of anesthesia drugs, anemia, recurrence of the disease, and bad mood. 1. Effect of anesthesia drugs: the anesthesia is not fully metabolized within a short period of time after the surgery, which may also lead to dizziness, and it is necessary to have an interview with the doctor; 2. Anemia: if the patient has anemia, it may also lead to dizziness, and it is recommended to go to the regular hospital to check the blood routine in time; 3. Relapse: Relapse of disease may also cause dizziness, which needs to be informed to the doctor in time and given appropriate treatment; 4. Adverse emotions: anxiety and irritability can also lead to postoperative dizziness. Adverse emotions can affect physical health, and family members need to take good care of them after surgery. Abnormalities after surgery for high blood pressure should be promptly informed to the doctor and appropriate treatment should be given.
