Introduction
In general, dizziness and unsteadiness may be caused by various factors such as hypoglycemia, orthostatic hypotension, anemia, cervical spondylosis, or Ménière's disease. When blood glucose levels drop, the brain receives less energy, affecting normal brain function—particularly areas related to balance and coordination—leading to dizziness and difficulty maintaining balance. Promptly consuming sugary foods or drinks, such as glucose water or candy, is recommended.
Dizziness and unsteadiness when standing are commonly caused by various factors such as hypoglycemia, orthostatic hypotension, anemia, cervical spondylosis, or Ménière's disease. It is recommended to seek medical attention promptly to determine the underlying cause and receive appropriate, symptom-based treatment under the guidance of a qualified physician. Detailed explanations are as follows:
1. Hypoglycemia
Skipping meals for prolonged periods may lead to hypoglycemia. When blood sugar levels drop, the brain receives insufficient energy, impairing normal brain function—particularly areas responsible for balance and coordination—resulting in dizziness and instability when standing. Immediate intake of sugary foods or drinks, such as glucose water or candy, is advised.
2. Orthostatic Hypotension
When rising suddenly from a sitting or lying position, blood may not be rapidly redistributed to the brain, causing a temporary drop in blood pressure and resulting in dizziness and unsteadiness. To prevent this, change positions slowly and avoid sudden standing.
3. Anemia
Anemia is usually caused by impaired hematopoietic function, leading to insufficient quantity or quality of red blood cells. This reduces the blood’s oxygen-carrying capacity, failing to meet the body’s oxygen demands, thereby causing dizziness, lightheadedness, and difficulty maintaining balance. Symptoms may include pale complexion and fatigue. Patients should, under professional medical supervision, take medications such as ferrous sulfate tablets, ferrous succinate tablets, or danazol capsules to alleviate symptoms.
4. Cervical Spondylosis
Cervical spondylosis is primarily caused by degenerative changes in the intervertebral discs and bone spurs in the cervical spine. Compression of the vertebral artery or irritation of the sympathetic nerves can impair cerebral blood supply and neural regulation, leading to dizziness and unsteadiness. It is often accompanied by neck pain and limited neck movement. Under a doctor’s guidance, patients may use medications such as enteric-coated aspirin tablets, indomethacin tablets, or betahistine mesylate tablets for treatment.
5. Ménière's Disease
Ménière's disease may result from an imbalance in the production and absorption of endolymphatic fluid, causing abnormal accumulation of fluid in the inner ear. This affects the organs responsible for balance, leading to vertigo and postural instability. Additional symptoms may include tinnitus and hearing loss. As directed by a physician, patients may take medications such as racemic anisodamine tablets, betahistine hydrochloride tablets, or mecobalamin tablets to relieve symptoms.
Maintaining a regular daily routine, ensuring adequate sleep and rest, and avoiding chronic late-night hours can support overall recovery and well-being.
