There are many reasons for dizziness, which may be due to poor nutrition, anemia or hypoglycemia, or mental stress, overwork, anxiety, insomnia, and neurasthenia. Some patients with anxiety disorder and depression will also have dizziness, such as those with anemia. Because of poor blood and oxygen supply to the brain, dizziness, malnutrition, poor physique, and hypoglycemia will also lead to insufficient blood supply to the brain and poor oxygen supply to brain cells, which will lead to dizziness. There are also some patients with hypertension whose blood pressure is poorly controlled, leading to arteriosclerosis and dizziness. Therefore, patients need to go to the hospital to improve various examinations, such as blood routine examination, brain CT, brain MRI. Usually, they also need to pay attention to rest and exercise regularly and properly, such as swimming.
