What is vertigo and how does vertigo differ from general dizziness? 

Vertigo is a specific medical symptom where you feel as though you or your surroundings are spinning, tilting, or moving when you are actually perfectly still. While people often use the terms vertigo and dizziness interchangeably, they describe different physical sensations. General dizziness is a broad term that covers feelings of being lightheaded, off balance, or faint, whereas vertigo is a distinct sensation of motion that often stems from a problem within the inner ear or the brain. 

In the UK, balance disorders are a common reason for GP visits. Distinguishing between a spinning sensation and a general feeling of instability is the first step in helping your doctor identify the underlying cause. While most cases of vertigo are related to minor inner ear issues that resolve with time or simple physical manoeuvres, persistent or sudden onset symptoms require careful medical evaluation to rule out more serious conditions.

• Common causes of vertigo including BPPV and Labyrinthitis 

• Why the vestibular system in the inner ear is central to balance 

• Behavioural signs and associated symptoms like nausea and tinnitus 

• When dizziness indicates a cardiovascular rather than an ear issue 

• Red flag symptoms that require immediate emergency medical attention 

Defining the sensation of vertigo 

Vertigo is more than just feeling unsteady; it is a sensory hallucination of movement. Patients often describe it as feeling like they have just stepped off a fast playground roundabout. This sensation can be constant or triggered by specific head movements, such as rolling over in bed or looking up at a high shelf. Because the brain receives conflicting signals about the body’s position in space, vertigo is frequently accompanied by physical symptoms like nausea, vomiting, and a loss of balance that can lead to falls. 

The most common form is Benign Paroxysmal Positional Vertigo (BPPV), which occurs when tiny calcium crystals in the inner ear become dislodged and move into the balance canals. This causes brief but intense bursts of spinning whenever the head changes position. Other types of vertigo may be caused by inflammation of the inner ear nerves, such as vestibular neuritis, or more chronic conditions like Meniere disease. 

How does dizziness differ from vertigo? 

Dizziness is a non specific umbrella term used to describe several different sensations of impaired spatial orientation. Unlike vertigo, general dizziness does not usually involve a spinning sensation. Instead, it might feel like a momentary swimming in the head or a feeling that you are about to pass out. This is often referred to medically as light-headedness or presyncope. 

Another form of dizziness is disequilibrium, which is a feeling of being unsteady on your feet without any sensation in the head. This is often linked to joint problems, muscle weakness, or issues with the nerves in the feet. While vertigo is almost always related to the vestibular system or the neurological pathways in the brain, general dizziness can be caused by anything from low blood sugar and dehydration to anxiety or heart rhythm problems. 

What are the primary causes of balance issues? 

The causes of balance issues vary depending on whether the symptom is true vertigo or general dizziness. Vertigo is typically categorised as peripheral, meaning it originates in the inner ear, or central, meaning it originates in the brain. Peripheral vertigo is far more common and usually less severe than central vertigo. 

Peripheral and central triggers 

Peripheral triggers include viral infections that cause Labyrinthitis or a buildup of fluid pressure in the ear as seen in Meniere disease. Central triggers, which are less common, include migraines, multiple sclerosis, or in rare cases, tumors affecting the balance nerve. General dizziness is often triggered by a sudden drop in blood pressure when standing up, known as orthostatic hypotension, or by side effects from certain medications like blood pressure pills or sedatives. 

Comparison: Vertigo vs General Dizziness 

Feature	Vertigo	General Dizziness (Light-headedness)
Sensation	Spinning, whirling, or tilting	Faintness, floating, or wooziness
Primary Source	Inner ear or brain	Heart, blood pressure, or metabolic
Nausea	Very common and often severe	Occasional or mild
Duration	Seconds to days	Usually brief or situational
Trigger	Head movement or ear infection	Standing up quickly or dehydration
Balance	Significantly impaired	Feeling unsteady but can usually walk

To Summarise 

Vertigo is a specific type of dizziness characterised by a false sensation of spinning or motion, usually caused by inner ear disturbances. General dizziness is a broader feeling of being lightheaded or off balance, often related to blood pressure or systemic issues. Identifying which sensation you are experiencing helps healthcare professionals narrow down the cause and provide the correct treatment, whether that involves physical therapy for the ear or managing a primary health condition. 

If you experience severe, sudden vertigo accompanied by a sudden change in vision, difficulty speaking, facial drooping, or weakness in your arms or legs, call 999 immediately.
