Why do I feel dizzy for just a second with Benign Paroxysmal Positional Vertigo (BPPV)?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Benign paroxysmal positional vertigo (BPPV) is a common inner ear disorder that causes brief episodes of dizziness or spinning sensations triggered by specific head movements, such as rolling over in bed, tilting your head back, or bending down. It occurs when tiny calcium carbonate crystals (otoconia) become dislodged from their normal location in the inner ear and shift into the semicircular canals, disrupting your body's balance signals to the brain. Episodes typically last less than a minute but can be intense and disorienting.

Because dizziness can stem from many different conditions—some minor, others more serious—it's important to identify the likely cause early. Take a free, instant, online symptom check to better understand your symptoms and confidently navigate your next steps.

Explanation

Benign Paroxysmal Positional Vertigo (BPPV) is a condition that makes you feel dizzy for a short time, especially when you change the position of your head. This happens because small particles in your inner ear, which help control balance, get dislodged and move into parts of the ear where they shouldn't be.

Why Does This Cause Dizziness?

The inner ear has tiny canals filled with fluid that help you keep your balance.
When these particles move into the canals, they can disrupt the fluid's movement.
This sends confusing signals to your brain about your body's position, causing dizziness.

Characteristics of BPPV:

The dizziness is usually brief, lasting less than a minute.
It often happens when you tilt your head or change positions, like getting out of bed.

Understanding BPPV can help you manage and seek appropriate treatment, such as maneuvers to reposition the particles in your ear. If you experience frequent dizziness, you can use Ubie's free AI-powered symptom checker to help identify possible causes and determine whether you should consult a healthcare provider for proper diagnosis and treatment options.
