The symptoms of dizziness in the afternoon may be caused by abnormal blood pressure, cervical spine disease, anemia, and hypoglycemic reaction. In some patients with hypertension treated with oral medication, the blood pressure is normally well controlled, but the symptoms of dizziness are caused by high blood pressure in the afternoon. Such hypertensive patients need to monitor their blood pressure regularly, and if necessary, they can switch to antihypertensive drug therapy. If there is cervical spine disease, usually overworked, after a day of work is not good for the cervical spine, can cause symptoms of dizziness. In addition, diabetic patients, if the application of hypoglycemic drugs, may cause hypoglycemic reaction, dizziness, panic and other symptoms, need to check the blood sugar to confirm the diagnosis. Dizziness can also occur after a long afternoon break and requires further examination at the hospital to confirm the diagnosis. Common tests include blood pressure, blood glucose, blood lipids, and routine blood tests.
