What causes dizziness in elderly people?

Generally, dizziness in elderly individuals may be caused by factors such as sleep deprivation, malnutrition, anemia, hypotension, cervical spondylosis, and others. Treatment may include general measures and medication under the guidance of a physician. Specific analyses are as follows:

1. Sleep Deprivation

Due to physiological changes such as reduced melatonin secretion and increased nighttime awakenings, older adults may experience decreased sleep quality and insufficient sleep. Chronic sleep deprivation can interfere with the brain's normal rest and recovery processes, affecting nervous system function and leading to dizziness. It is important to establish a regular sleep schedule and create a comfortable sleeping environment.

2. Malnutrition

Weakened digestive and absorptive capacity, reduced appetite, and unbalanced diets in the elderly can easily lead to malnutrition. This condition may cause anemia or neurological dysfunction, thereby triggering dizziness. A balanced diet should be maintained, with increased intake of foods rich in protein, iron, folic acid, and other essential nutrients.

3. Anemia

Anemia in the elderly is often due to malnutrition, chronic blood loss, or decreased bone marrow hematopoietic function. Anemia reduces the blood’s oxygen-carrying capacity, leading to cerebral hypoxia and resulting in dizziness. Symptoms may include pallor and palpitations. Patients should follow medical advice and take medications such as compound ferrous sulfate and folic acid tablets, ferrous fumarate granules, or iron dextran injection.

4. Hypotension

Hypotension may be related to genetic factors, prolonged bed rest, dehydration, and other causes. Low blood pressure leads to inadequate cerebral perfusion, causing dizziness. Symptoms may include blurred vision, lightheadedness, and unsteadiness when standing. Medications such as Shengmai Yin oral solution, midodrine hydrochloride tablets, or fludrocortisone acetate tablets may be used under medical supervision.

5. Cervical Spondylosis

Cervical spondylosis is mainly caused by degeneration of intervertebral discs, excessive strain on the cervical spine, and poor posture. Spinal lesions may compress the vertebral artery or sympathetic nerves, leading to insufficient cerebral blood supply or nerve dysfunction, thus causing the aforementioned symptoms. Additional symptoms may include neck pain and stiffness. Treatment may involve medications such as ibuprofen gel, Jingkang capsules, or eperisone hydrochloride tablets, as prescribed by a doctor.

Elderly individuals should maintain healthy lifestyle habits, including regular作息 (sleep-wake cycles), a balanced diet, moderate exercise, prevention of cervical spondylosis, and regular monitoring of blood pressure and nutritional status to reduce the occurrence of discomforts such as dizziness.
