Elderly people who do not pay attention to nutritional care are prone to anemia. In addition, anemia can be secondary to dyspepsia, peptic ulcer, gastrointestinal bleeding, and chronic inflammatory diseases in elderly patients. If there is dizziness accompanied by weakness and pallor, the possibility of anemia should be considered. In a healthy state, the amount of hematopoietic tissue present in the body as well as the quality and quantity of hematopoiesis has decreased in the elderly, and the aging of the red blood cells themselves makes their utilization of iron much less than before. Therefore, elderly people are prone to anemia if they do not pay attention to nutritional care. In addition. Patients with dyspepsia, peptic ulcer, gastrointestinal bleeding and chronic inflammatory diseases can be secondary to anemia.

Patients with cervical spondylosis such as osteophytes and herniated discs often experience neck tightness, limited flexibility, occasional pain, numbness and coldness in the fingers. If cervical vertebral hyperplasia squeezes the vertebral artery in the neck and causes insufficient blood supply to the brain, it can cause dizziness, which should then be seen by an orthopedic surgeon for timely treatment of the primary cause in order to relieve the symptoms of dizziness.
