BPPV affects the balance organs in the inner ear and is triggered by certain head movements. When people have BPPV, if they move their head in certain directions, they can experience dizziness, lightheadedness, loss of balance, nausea or a spinning sensation (vertigo) for up to a minute. These effects are caused by calcium crystals coming out of where they’re supposed to be in the balance organ. Treatment of BPPV is carried out by a physiotherapist or balance specialist and includes a series of head movements that moves the crystals back to where they should be in the balance organ.
