Generally, when dizziness occurs, sometimes it is accompanied by vertigo, and if there are gastrointestinal symptoms such as nausea, vomiting, and so on, it should be seen by a doctor for emergency treatment, rapid diagnosis, and rapid identification of the cause for targeted treatment to achieve a good effect. The causes are very complex, including Meniere’s disease, otolith syndrome, posterior circulation disorders, cervical spondylosis (especially vertebral artery type cervical spondylosis), and other cardiovascular and cerebrovascular diseases, or other brain diseases.

Therefore, it should be a multi-disciplinary expert consultation for examinations to find the cause and carry out etiological treatment, which can achieve a truly good clinical effect. This is a comprehensive examination process, including orthopedics, otorhinolaryngology, neurology, internal medicine, surgery, and other departments, which requires imaging diagnosis, laboratory tests, ultrasound, and other examinations. This process is complex, and good treatment methods can only be obtained after diagnosis, which will not delay the condition.

Therefore, there are many causes of dizziness and nausea. For example, dizziness and nausea caused by cerebrovascular diseases such as hypertension, hypotension, insufficient cerebral blood supply, brain infection, cerebral infarction, cerebral hemorrhage, and cervical spondylosis belong to neurological diseases and it is recommended to visit the neurology department. Dizziness and nausea caused by vestibular neuritis, Meniere’s syndrome, and otolith syndrome are recommended to visit the otorhinolaryngology department. Dizziness and nausea caused by gastrointestinal diseases, gastroenteritis, and other conditions are recommended to visit the gastroenterology department. For other causes such as anemia, poor sleep quality, and anxiety, it is recommended to ensure adequate sleep, pay attention to nutritional supplements, and relieve stress.

The patient experiences dizziness and nausea, which requires medical attention from the neurology department to conduct examinations and determine the cause of the illness for targeted treatment. Since there are many causes of dizziness and headache, such as subacute cerebral infarction, cerebral hemorrhage, or due to intracranial tumors and space-occupying lesions, dizziness and vomiting can be severe and require comprehensive physical examinations by doctors to establish a diagnosis and actively take medication for treatment. If treatment is not timely, some diseases may lead to patient death or risk the occurrence of dysautonomia with impaired physical activity, therefore, it is necessary to investigate.
