There are many causes of dizziness, and the common causes are usually anemia, cervical spondylosis, benign positional vertigo, cerebellar infarction or hemorrhage, hypertension or hypotension, hyperglycemia or hypoglycemia, etc. 1. anemia: anemia is one of the common causes of dizziness, because the concentration of red blood cells and hemoglobin in the blood decreases, the ability of the blood to carry oxygen decreases, and the blood supply to the brain is insufficient, leading to symptoms of dizziness; 2. Cervical spondylosis: the patient’s cervical disc protrusion partially compresses the nerves or blood vessels, which can lead to nerve dysfunction or affect the blood supply to the brain, resulting in dizziness and other symptoms; 3. Benign positional vertigo: that is, otolithosis, which mainly manifests as strong vertigo when the head position changes and usually lasts for a short period of time; 4. Cerebellar infarction or hemorrhage: cerebellar infarction or hemorrhage belongs to cerebrovascular disease, which can produce symptoms such as dizziness, vomiting, and High or low blood pressure: High blood pressure can easily cause cerebral arteriosclerosis, which leads to narrowing of blood vessel lumen and thickening of blood vessel wall, which can easily cause poor blood flow, resulting in insufficient blood supply to the brain and causing dizziness. Low blood pressure also tends to cause dizziness caused by insufficient blood supply to the brain; 6. Hyperglycemia or hypoglycemia: hypoglycemia appears earlier and the symptoms should be obvious, accompanied by weakness, panic, sweating and other symptoms. Patients with hyperglycemia will have symptoms of dizziness when their blood sugar rises significantly, accompanied by weakness, thirst, polyuria, and in severe cases, hypotension and drowsiness.
