Episodes of loss of balance may seem temporary at first, but their recurrence can affect the ability to walk and perform daily activities and increase the risk of falls and injuries. Recurrent loss of balance may be accompanied by dizziness, a sensation that the surroundings are spinning, or a feeling of unsteadiness, and sometimes by nausea, blurred vision, or weakness in one limb.
Loss of balance is not a disease in itself, but rather a symptom that may be associated with inner ear disorders, nervous system problems, low blood pressure, or certain chronic diseases and medications. Identifying the cause depends on the nature of the symptoms, accompanying signs, and the duration of the episodes; therefore, recognizing warning signs and diagnostic methods helps ensure the right treatment is administered at the right time.
What is recurrent loss of balance?
Recurrent loss of balance refers to repeated episodes in which a person feels unsteady or as if they are about to fall, and may have difficulty walking in a straight line or maintaining posture while standing or moving. An episode can last for seconds, minutes, or longer. They may appear suddenly or develop gradually, and may be accompanied by dizziness, blurred vision, or nausea.
Balance loss happens when coordination among the inner ear, eyes, muscles, joints, and nervous system, which determine body position and maintain stability, is disrupted. Recurrent episodes of losing balance are not a diagnosis on their own; they are a symptom that requires further investigation to identify the underlying cause, especially if they become more frequent or are accompanied by other neurological or auditory symptoms.
How does the body maintain its balance?
Maintaining balance depends on the coordination of several systems that continuously send the brain information about the body’s posture and movement. The vestibular system in the inner ear detects head movement and its relationship to gravity, while the eyes provide a visual reference to the surrounding environment, and sensory receptors in the muscles, joints, and skin convey information about the position of the limbs and the body.
The brain, particularly the cerebellum and the brainstem, receives and compares these signals, then sends rapid commands to the muscles of the eyes, trunk, and limbs to maintain stable vision and correct body posture while standing and walking. Therefore, disruption in any part of this system, or a mismatch in the signals it receives, can lead to unsteadiness, dizziness, or loss of balance.
Symptoms associated with loss of balance
Symptoms associated with loss of balance vary by cause; they may appear suddenly or gradually and last from a few seconds to hours or longer. The most common symptoms include:
- A sense of unsteadiness or body swaying
- Vertigo or a sensation that the surroundings are spinning
- Staggering and difficulty walking in a straight line
- A feeling of being about to fall or actually falling
- Lightheadedness or a sensation of impending fainting
- Blurred vision or difficulty focusing the eyes
- Nausea or vomiting
- Tinnitus, hearing loss, or a sensation of ear fullness
- Confusion or difficulty with spatial orientation
- Fatigue and fear or anxiety about recurring episodes
Some of these symptoms may occur on their own, while in other cases several symptoms occur together; their pattern, duration, and triggering factors help identify the likely cause of the imbalance.
What are the causes of recurrent loss of balance?
Recurrent loss of balance may result from a disorder of the inner ear, the nervous system, or the circulatory system, and may also be associated with impaired vision, muscle weakness, or certain medications. In some cases, several factors may interact, particularly in older adults. The most common causes include:
Inner ear disorders
These are among the most common causes of dizziness and loss of balance, and include:
- Benign paroxysmal positional vertigo (BPPV), triggered by specific head movements
- Vestibular neuritis
- Labyrinthitis (inflammation of the inner ear)
- Ménière’s disease, sometimes accompanied by tinnitus and hearing loss
- Fluid accumulation or inner ear injuries
- Acoustic neuroma or vestibular schwannoma (less common)
Neurological disorders
Diseases affecting the brain or nerves can impact motor coordination and the perception of body position, such as:
- Vestibular migraine
- Stroke or transient ischemic attack (TIA)
- Multiple sclerosis
- Parkinson’s disease
- Cerebellar diseases or injuries
- Peripheral neuropathy, especially in diabetic patients
- Head injuries
Blood pressure and circulatory disorders
Low blood pressure upon standing may temporarily reduce blood flow to the brain, causing lightheadedness and unsteadiness. Similar symptoms may also occur with dehydration, anemia, heart rhythm disturbances, or poor circulation.
Vision, muscle, and joint disorders
Balance depends on clear vision, sufficient muscle strength, and a good sense of limb position; therefore, poor vision, arthritis, weak leg muscles, or gait disorders can lead to frequent loss of balance.
Metabolic causes and nutrient deficiencies
This imbalance may be linked to low blood sugar, thyroid disorders, vitamin B12 deficiency, electrolyte imbalances, or malnutrition; diabetes may also damage the nerves that control sensation in the feet and body posture.
Medicines and substances affecting balance
Loss of balance may occur as a side effect of certain sedatives, sleep aids, anticonvulsants, antidepressants, blood pressure medications, and certain antibiotics that affect the inner ear. Alcohol consumption can also impair motor coordination and balance.
Anxiety and psychological causes
Anxiety and panic attacks may cause a feeling of dizziness or unsteadiness, and imbalance can persist after recovery from a vestibular disorder in what is known as Persistent Postural Perceptual Dizziness (PPPD). However, organic causes should be ruled out before considering the symptoms to be psychological.
The cause cannot be determined from the presentation alone; the episode’s duration, triggers, and any accompanying auditory, neurological, or cardiac symptoms help guide the diagnosis.
Causes of loss of balance while walking
Loss of balance may be particularly noticeable while walking, as this movement requires constant coordination between the inner ear, vision, the nervous system, and the leg muscles. The likely cause varies depending on the type of gait and accompanying symptoms; the most common patterns include:
- Leaning to one side accompanied by dizziness: May indicate a disorder of the inner ear or the vestibular nerve.
- Walking with a wide base and staggering: May be linked to a cerebellar disorder, as the cerebellum is responsible for movement coordination.
- Walking with short, slow steps: May be associated with Parkinson’s disease and certain neurological disorders.
- Stumbling accompanied by numbness in the feet: May result from peripheral neuropathy caused by diabetes or vitamin B12 deficiency.
- Dragging one leg or weakness on one side of the body: May be linked to a stroke or another neurological issue, especially if the onset is sudden.
- Instability in dark places: May indicate poor vision or impaired proprioception (sense of foot position).
- Swaying due to leg weakness or joint pain: May occur with muscle weakness, arthritis, or following a period of inactivity.
- Loss of balance after taking specific medication: May be a side effect of sedatives, sleep aids, blood pressure medications, or certain neurological drugs.
Loss of balance while walking may be more noticeable when changing direction, climbing stairs, or walking on uneven ground. Assessing gait, muscle strength, sensation, and balance helps identify the affected system and the likely cause.
Causes of sudden loss of balance
A sudden loss of balance may be caused by a brief, minor disturbance, such as a rapid change in head position, but it can also signal a neurological or cardiac emergency. The most common causes include:
- Benign Paroxysmal Positional Vertigo (BPPV): A brief episode of vertigo and unsteadiness triggered by rising, rolling over in bed, or moving the head.
- Vestibular neuritis or inner ear inflammation: Causes sudden, severe vertigo with nausea and difficulty walking; inner ear inflammation may also cause hearing loss.
- Ménière’s disease: Sudden episodes of vertigo accompanied by tinnitus, hearing loss, or a sensation of fullness in the ear.
- Vestibular migraine: May cause vertigo and imbalance along with headache or sensitivity to light and sound; it can sometimes occur without a distinct headache.
- Sudden drop in blood pressure: Often occurs after standing up quickly and may cause lightheadedness or a near-fainting sensation.
- Low blood sugar or dehydration: May include sweating, trembling, weakness, and confusion.
- Heart rhythm disorders: May reduce blood flow to the brain, causing loss of balance or fainting.
- Medication side effects: Particularly after starting a new medication or adjusting the dosage.
- Stroke or transient ischemic attack (TIA): May cause a sudden loss of balance and coordination, especially if accompanied by weakness or numbness on one side, or disturbances in speech or vision.
A sudden loss of balance requires calling an ambulance immediately if it is accompanied by facial drooping, weakness in a limb, difficulty speaking, double vision, a new severe headache, or loss of consciousness.
The difference between loss of balance, dizziness, and vertigo
| Comparison point | Loss of balance | Dizziness | Vertigo |
|---|---|---|---|
| Definition | Inability to maintain body stability and balance | A general feeling of lightheadedness, confusion, or unsteadiness | A false sensation that you or your surroundings are moving |
| Primary sensation | Swaying or a tendency to fall | Lightheadedness or feeling faint | Spinning or rotating sensation |
| When it occurs | Often while standing, walking, or changing direction | Can occur in any position and may worsen when standing | May start spontaneously or after head movements |
| Associated symptoms | Unsteady gait, difficulty walking, and falls | Weakness, sweating, blurred vision, and nausea | Nausea, vomiting, nystagmus, and sometimes tinnitus |
| Common causes | Disorders affecting balance, nerves, vision, muscles, or joints | Low blood pressure, low blood sugar, dehydration, anemia, medications, or anxiety | Inner ear disorders, vestibular migraine, and certain neurological conditions |
When is a loss of balance dangerous?
Loss of balance is considered serious when it occurs suddenly or is accompanied by symptoms that may indicate a stroke or a serious heart or nervous system disorder.
Signs requiring immediate emergency care
- Sudden weakness or numbness in the face, arm, or leg, especially on one side
- Drooping on one side of the face
- Difficulty speaking or understanding others
- Sudden loss of vision, blurred vision, or double vision
- Sudden, severe, and unusual headache
- Loss of consciousness or a seizure
- Sudden inability to stand or walk
- Chest pain, shortness of breath, or irregular heartbeat
- Loss of balance following a head injury
- Repeated vomiting accompanied by severe dizziness and inability to move
You should call an ambulance even if the neurological symptoms disappear after a few minutes, as they may be caused by a transient ischemic attack that precedes a stroke.
How is recurrent loss of balance diagnosed?
Diagnosis starts with a thorough medical history to identify when the episodes began, how long they last, and what triggers them, such as standing up or moving the head. The doctor will also inquire about any accompanying symptoms, including hearing loss, headaches, numbness, or palpitations. Additionally, the physician will ask about any chronic conditions, medications currently being taken, and any previous falls the patient may have experienced.
The doctor may then perform the following tests, depending on the situation:
- Clinical examination: Measuring blood pressure while lying down and standing; examining the ears, vision, muscle strength, sensation, and neurological reflexes.
- Gait and balance tests: Observing walking patterns, testing the ability to stand with feet together, and assessing the ability to change direction.
- Dix-Hallpike maneuver: Helps diagnose benign paroxysmal positional vertigo (BPPV).
- Hearing test: To detect hearing loss or inner ear disorders.
- Videonystagmography (VNG) or electronystagmography (ENG): Records eye movements to assess the vestibular system and balance-related nerves.
- Video Head Impulse Test (vHIT): Measures eye response to rapid head movements.
- Vestibular Evoked Myogenic Potential (VEMP) test: Assesses the function of specific parts of the inner ear.
- Rotary chair test or posturography: Determines the extent to which the inner ear, vision, and proprioception contribute to the problem.
- Blood tests: May include blood count, blood sugar, electrolytes, thyroid function, and vitamin B12 levels.
- Cardiac tests: Such as an electrocardiogram (ECG) or Holter monitoring, if palpitations or fainting occur.
- CT or MRI scans: Ordered if a stroke, tumor, or central nervous system disorder is suspected.
Not every patient needs all of these tests; the doctor selects the appropriate tests based on the patient’s symptoms and the results of the initial examination.
Treatment of recurrent loss of balance based on the cause
No one-size-fits-all treatment exists for all cases of balance loss; treatment depends on the cause, symptom severity, and fall risk. A treatment plan may include:
- Benign Paroxysmal Positional Vertigo (BPPV): The Epley maneuver returns calcium crystals to their normal position in the ear; the procedure may need to be repeated.
- Vestibular neuritis or inner ear inflammation: Doctors may prescribe vertigo and nausea medications for a short time, followed by vestibular rehabilitation to help the brain adapt.
- Ménière’s disease: Reducing salt intake and avoiding smoking and caffeine, alongside doctor-prescribed medications for vertigo or diuretics; other procedures may be used in severe cases.
- Vestibular migraine: Avoiding headache triggers and regulating sleep and meals, along with medications to treat or prevent attacks when necessary.
- Orthostatic hypotension: Increasing fluid intake, rising gradually, and reviewing medications; a doctor may recommend compression stockings or specific medications.
- Hypoglycemia, anemia, or vitamin B12 deficiency: Correcting the underlying condition through medication, supplements, or dietary adjustments.
- Neuropathy and neurological disorders: Managing diabetes or treating the neurological condition, combined with physical therapy and the use of walking aids if needed.
- Vision impairment or muscle and joint problems: Correcting vision, treating joint disorders, strengthening muscles, and improving gait.
- Medication-induced imbalance: Adjust the dosage or switch the medication under a doctor’s supervision; do not discontinue use on your own.
- Anxiety and Persistent Perceptual-Postural Dizziness (PPPD): A combination of vestibular rehabilitation, behavioral therapy, and appropriate medication may be beneficial.
Medications for vertigo and nausea should be used with caution because they may cause drowsiness and increase the risk of falls; furthermore, long-term use may slow the brain’s recovery in some vestibular disorders.
