Dizziness while driving is caused by cervical spondylosis, insufficient blood supply to the brain, mental stress, and elevated blood pressure. The presence of osteoarthritis or nerve root syndrome in the cervical spine area will lead to disc herniation and compression of the neighboring nerve roots, thus causing a series of clinical symptoms. When the patient maintains a sitting position for a long time, it will lead to severe compression of the vertebral artery, thus causing the symptoms of dizziness. Emotional tension while driving will affect the blood volume of the brain, thus causing the brain to cause localized slight edema, causing dizziness. Patients with high blood pressure and mental stress while driving can also cause insufficient blood supply to the brain, exacerbating the phenomenon of dizziness. Heart disease, resulting in lower blood pressure and reduced heart output, can also affect the blood supply to other parts of the body, resulting in dizziness and fatigue, and stomach disorders can also cause similar symptoms.
