The symptoms of dizziness and coughing may be due to the following reasons: a. Some people cough too hard, which may cause a rise in blood pressure. Inflammation of the inner ear caused by infection in some coughing patients may also cause changes in inner ear pressure, resulting in dizziness when coughing; third, coughing in some patients with cerebral vascular stenosis may lead to hypoxia, which may cause a transient spasm of the cerebral vessels, aggravating the lack of blood supply to the brain and causing dizziness. Therefore, the causes of coughing and dizziness are very diverse and should be seen immediately at a hospital to clarify the cause and treat the symptoms.
