Vertigo is a common symptom that can be unsettling and confusing. It often feels like the world is spinning or tilting, even when you are standing still. This sensation is closely linked to the vestibular system, a complex part of the body that helps control balance and spatial orientation. Understanding what vertigo is, how the vestibular system works, and what causes these symptoms can help you better manage your health and seek the right treatment.
What Vertigo Feels Like
Vertigo is more than just feeling dizzy. People experiencing vertigo often describe it as:
A spinning sensation, as if the room or themselves are moving
Feeling off-balance or unsteady when standing or walking
Nausea or vomiting linked to the spinning feeling
Difficulty focusing or concentrating due to the sensation of movement
For someone without medical training, vertigo can be frightening because it disrupts normal movement and balance. It can make simple tasks like walking or turning your head feel dangerous.
What Does Vestibular Mean?
The term vestibular relates to the vestibular system, which is part of the inner ear and brain that helps control balance and eye movements. The word comes from vestibule, meaning an entrance or a small space, which in this case refers to the part of the inner ear that detects motion and position.
Other words related to vestibular include:
Balance system
Equilibrium system
Inner ear balance organs
These terms all point to the body’s way of sensing movement and maintaining stability.
The Organs That Make Up the Vestibular System
The vestibular system includes several key parts:
Semicircular canals: Three tiny, fluid-filled tubes positioned at right angles to each other. They detect rotational movements of the head, like turning or nodding.
Otolith organs (utricle and saccule): These detect linear movements, such as moving forward or up and down, and the position of the head relative to gravity.
Vestibular nerve: This nerve carries signals from the inner ear to the brain about head movement and position.
Brainstem and cerebellum: These brain areas process vestibular signals and coordinate balance, posture, and eye movements.
Together, these organs send constant information to the brain about where your head is and how it is moving. This helps you keep your balance and maintain a stable view of the world.
How the Vestibular System Affects How We Feel
When the vestibular system works well, you feel steady and balanced. Your eyes can focus clearly even when you move your head quickly. Your body knows how to adjust your posture to avoid falling.
If the vestibular system is not working properly, it can cause:
Vertigo or dizziness
Unsteady walking or a feeling of falling
Blurred vision or difficulty focusing
Nausea or motion sickness
For example, if the fluid in the semicircular canals moves incorrectly or if the brain receives mixed signals, you might feel like the room is spinning even though you are still.
Common Causes of Vertigo
Vertigo can result from many different conditions affecting the vestibular system, such as:
Benign paroxysmal positional vertigo (BPPV): Small crystals in the inner ear become dislodged and move into the semicircular canals, causing brief episodes of spinning when you change head position.
Vestibular neuritis or labyrinthitis: Inflammation of the inner ear or vestibular nerve, often caused by viral infections, leading to sudden vertigo and balance problems.
Meniere’s disease: A disorder involving fluid buildup in the inner ear, causing vertigo, hearing loss, and ringing in the ears.
Head injury or trauma: Damage to the vestibular organs or brain areas that process balance signals.
Migraines: Some people experience vertigo as part of migraine symptoms.
Understanding the cause is important because treatment varies depending on the condition.
How Physiotherapists Can Help with Vertigo
Physiotherapists with special training in vestibular rehabilitation can diagnose and treat many causes of vertigo. They use specific tests to identify which part of the vestibular system is affected. For example, they may perform head movement tests or balance assessments.
Treatment may include:
Vestibular rehabilitation exercises: These exercises help retrain the brain to adapt to changes or damage in the vestibular system. They often involve head and eye movements, balance training, and walking exercises.
Canalith repositioning manoeuvres: For BPPV, physiotherapists guide patients through movements that help move the dislodged crystals out of the semi-circular canals.
Balance and gait training: To improve stability and reduce the risk of falls.
Education and advice: Teaching patients how to manage symptoms and avoid triggers.
Many people find significant improvement with physiotherapy, reducing dizziness and improving their quality of life.
When to See a Healthcare Professional
If you experience vertigo that lasts more than a few minutes, happens frequently, or is accompanied by other symptoms like hearing loss, severe headache, weakness, or difficulty speaking, you should see a healthcare provider, and in some cases an emergency department. They can perform a thorough evaluation to rule out serious causes and recommend appropriate treatment.
Summary
Vertigo is a symptom that often signals a problem with the vestibular system, the body’s balance control centre located in the inner ear and brain. It can feel like spinning, dizziness, or loss of balance. The vestibular system includes the semi-circular canals, otolith organs, vestibular nerve, and brain areas that work together to keep you steady and oriented.
Many conditions can cause vertigo, from neurological conditions, inner ear infections, to displaced crystals in the ear. Physiotherapists with advanced training can diagnose these problems and offer effective treatments like vestibular rehabilitation exercises and repositioning manoeuvres.
