What is the difference between vertigo and dizziness?
Last updated September 3, 2026.
Dizziness is the umbrella term. Vertigo is specific: the room spins or you spin, often with nausea, usually from the inner ear. Lightheadedness (about to faint) points to blood pressure, hydration, or the heart; unsteadiness without spinning points to balance or nerves. The common vertigo causes: BPPV (brief spins triggered by rolling in bed or looking up, from loose inner-ear crystals, curable in minutes with the Epley maneuver), vestibular neuritis (days of spinning after a virus), Meniere's (episodes plus ear fullness, ringing, hearing loss), and migraine-related vertigo. The split matters because the fixes differ: BPPV-pattern spinning is an office visit with a quick cure, while faintness needs hydration, slow standing, and possibly a cardiac or blood check. The ER patterns: vertigo with double vision, slurred speech, one-sided weakness, inability to walk straight, or a worst-ever headache (stroke until proven otherwise), and lightheadedness with chest pain, palpitations, or fainting (cardiac until evaluated). During attacks: sit or lie down immediately, because vertigo plus standing equals falls.
What to do
- Room spinning: vertigo, usually inner ear.
- About to faint: blood pressure, hydration, or heart.
- Spins when rolling in bed: BPPV; the Epley maneuver fixes it.
- Vertigo plus double vision, slurred speech, weakness: ER.
- Sit or lie down during attacks: falls are the real danger.
