There are several common causes for dizziness and vomiting. First of all, we should consider whether the patient has dizziness, nausea and vomiting caused by cerebral insufficiency. If the symptoms of dizziness and cerebral insufficiency occur while working, we should consider whether they are caused by cervical spondylosis, and we need to do cervical spine MRI and CT to make a clear diagnosis. When dizziness and vomiting suddenly appear during work, we should also consider whether the patient has bradycardia. In particular, in third degree AV block or high AV block, the blood supply is affected during the activity and the symptoms of dizziness, nausea and vomiting occur. If you experience dizziness and vomiting while working, you should also consider whether you have cerebrovascular disease or cerebrovascular abnormalities, hemorrhage or infarction caused by increased blood pressure.
