What is the Epley maneuver?

A series of head position changes performed to relocate displaced inner ear crystals back to their proper chamber. It cures BPPV in about 80% of cases in one session.

Dizziness and Nausea: Vestibular Causes and Quick Relief

Important Disclaimer

This guide is for informational purposes and does not replace professional medical advice. If you are experiencing a medical emergency, call 911 or your local emergency services immediately.

Overview

Dizziness and nausea are tightly linked because the vestibular system (inner ear balance center) connects directly to the brain's vomiting center. When the balance system sends conflicting signals, nausea is the natural result.

Possible Causes

BPPV

common

Displaced calcium crystals in the inner ear cause brief spinning episodes with intense nausea triggered by head movements.

View Condition Details

Labyrinthitis

less-common

Inner ear inflammation (usually viral) causes sustained vertigo with nausea, sometimes with hearing changes.

Motion Sickness

common

Sensory mismatch between visual input and vestibular signals triggers nausea during travel.

When It Is Serious

Sudden vertigo with hearing loss, double vision, difficulty speaking, or numbness may indicate stroke affecting the brainstem or cerebellum.

When It's Likely Benign

Brief spinning triggered by rolling over in bed or looking up, resolving in under a minute, is classic BPPV — highly treatable.
