Dizziness is a common clinical symptom and one of the more common complaints of patients. The main manifestations are dizziness of the head, heaviness of the head, shaking in the brain and the feeling of blurred eyes. The causes of dizziness are varied and require careful clinical examination for differential diagnosis. Dizziness is commonly associated with the following diseases, including: hypertension, cerebral blood supply deficiency, cranial trauma, neurological disorders, and fever. In addition to these, it can also be seen in anemia, heart disease, hypoglycemia, drug intoxication, vestibular problems, and cervical spine pathology. Poor rest can also cause dizziness. Dizziness can occur alone or in combination with headache. Patients who show dizziness, weakness, and pallor should promptly go to the hospital for laboratory tests to see if they are anemic. In addition to dizziness, patients with hypertension are often accompanied by headache, panic, irritability and other discomforts. Insufficient blood supply to the heart muscle due to coronary atherosclerosis can also cause dizziness due to insufficient blood supply to the brain. Patients who eat a meat-based diet or those with endocrine disorders should pay attention to the presence of dyslipidemia, as elevated blood lipids can also cause fatigue and weakness. Patients with cerebrovascular arteriosclerosis or stenosis may suffer from vascular problems, which may cause dizziness due to insufficient blood supply to the brain. Cervical spondylosis, which compresses the vertebral artery in the neck and causes insufficient blood supply to the brain, can also cause dizziness, in addition to stiffness in the neck, limited flexibility, and numbness in the fingers. Hypoglycemia, which is common in young people, can also cause dizziness and panic, dizziness on an empty stomach or during exertion, and in severe cases, convulsions and loss of consciousness. Respiratory alkalosis can be caused by emotional overstimulation or hyperventilation, which in turn can cause dizziness and weakness. Careful clinical differentiation of dizziness is required, combined with history, physical examination, and ancillary tests to establish the diagnosis.
