Loss of balance refers to difficulty in maintaining a stable posture, whether standing or in motion. This disorder is based on the dysfunction of at least one of the three systems that regulate stability: the vestibular system (inner ear), vision, and proprioception (muscle and joint sensors). When one of these systems sends contradictory information to the brain, the sensation of instability arises.
Chronic balance loss and professional life: an underestimated angle
Persistent balance disorders are not limited to the risk of falling. When they persist for several weeks, they profoundly alter the ability to work. Driving, prolonged standing, carrying loads, moving on construction sites or in warehouses: these common situations become risky, even impossible.
Cognitive fatigue often accompanies these episodes. The brain continuously mobilizes additional resources to compensate for the imbalance, which reduces concentration and responsiveness. Even seemingly sedentary office jobs are affected: quick head movements in front of a screen or rotations in a swivel chair can trigger dizziness in some individuals.
To delve deeper into the disease of balance loss and its causes, it is essential to distinguish between occasional forms and recurrent forms, as the consequences on daily activities differ radically.

Prolonged work stoppage, loss of confidence in physical abilities, and social isolation create a cycle that exacerbates symptoms. Among seniors still in the workforce, polypharmacy (notably antihypertensives) increases the risk of orthostatic hypotension, a cause of balance loss that is on the rise.
Inner ear and vestibular system: the mechanisms at play
The inner ear houses the vestibular apparatus, composed of three semicircular canals and two organs (utricle and saccule). The canals detect head rotations, while the utricle and saccule perceive linear accelerations and gravity. These sensors continuously send signals to the brain via the vestibular nerve.
When small crystals of calcium carbonate (otoliths) detach and migrate into a semicircular canal, they cause a benign paroxysmal positional vertigo (BPPV). This type of vertigo is triggered by changes in head position, such as turning in bed or suddenly lifting the head.
Other common vestibular disorders
- Vestibular neuritis corresponds to inflammation of the vestibular nerve, often of viral origin, causing intense rotary vertigo that lasts several days before gradually subsiding.
- Meniere’s disease combines episodes of vertigo with tinnitus and fluctuating hearing loss, related to an excess of fluid (endolymph) in the inner ear.
- Vestibular schwannoma (acoustic neuroma) is a benign tumor that develops on the vestibular nerve and causes progressive balance disorders, often accompanied by unilateral hearing loss.
In each of these cases, the ENT doctor or neurologist establishes the diagnosis through specific examinations (videonystagmography, audiometry, MRI). Accurate identification of the mechanism determines the choice of treatment.
Non-vestibular causes of balance disorders
Not all balance losses originate from the inner ear. Several other mechanisms produce similar symptoms.
Orthostatic hypotension causes feelings of discomfort when transitioning to a standing position. Blood pressure drops sharply, the brain receives less blood for a few seconds, and the sensation of imbalance occurs. This phenomenon particularly affects seniors treated with multiple antihypertensive medications.
Neurological disorders constitute another group of causes. Multiple sclerosis, certain cerebellar lesions, or spinal stenosis disrupt the nerve transmission between the brain and stabilizing muscles. Balance loss then gradually sets in, accompanied by gait disturbances.
The role of proprioception and medications
Proprioception, the ability to perceive the position of one’s body in space through receptors located in muscles and joints, decreases with age. When it weakens, the body compensates through vision and the vestibular system. If one of these pathways is also impaired, balance becomes precarious.
Some medications directly disrupt balance. Baclofen (muscle relaxant), anxiolytics, antiepileptics, and certain ototoxic antibiotics are among the most frequently involved substances. Any recent loss of balance warrants a review of the prescription with a doctor, especially in cases of polypharmacy.
Vestibular rehabilitation and appropriate treatments
Treatment depends on the identified cause. For BPPV, maneuvers to reposition the otoliths (Epley or Semont maneuver), performed by a trained physician or physiotherapist, often resolve the issue in one to three sessions.
Vestibular rehabilitation is the reference treatment for chronic disorders. It aims to train the brain to compensate for the faulty information by engaging the remaining systems. The exercises combine eye movements, position changes, and work on static and dynamic balance.
The Health Insurance has expanded the reimbursement of vestibular rehabilitation via teleconsultation since January 2025, facilitating access for patients living in rural areas where specialized physiotherapists are scarce.
Recent protocols integrating virtual reality into traditional vestibular exercises show promising results, particularly in reducing recurrences of BPPV in active patients, according to feedback presented at specialized physiotherapy conferences.
- BPPV is treated with liberating maneuvers, without medication.
- Vestibular neuritis first requires symptomatic treatment (antivertiginous), followed by early vestibular rehabilitation.
- Meniere’s disease is managed with a low-salt diet, diuretics, and, in resistant forms, more specific treatments discussed on a case-by-case basis.
- Orthostatic hypotension necessitates adjustments to medications and postural measures (getting up slowly, wearing compression stockings).
Consulting a doctor at the first episodes of balance loss remains the most effective approach. An isolated and brief vertigo does not necessarily indicate a serious pathology, but repeated episodes or those accompanied by hearing loss, unusual headaches, or gait disturbances require prompt evaluation. Early diagnosis shortens the duration of symptoms and limits complications, particularly the risk of falls in seniors.
