Benign Paroxysmal Positional Vertigo (BPPV)

Ear anatomy, with detail of stones in semicircular canal

Benign paroxysmal positional vertigo (BPPV) is caused by a problem in the inner ear. Tiny calcium "stones" inside your inner ear canals help you keep your balance. Normally, when you move a certain way-such as when you stand up or turn your head-these stones move around. Sometimes these stones move into an area of your inner ear called the semicircular canal. When you move your head in certain ways, the stones in your semicircular canal move. Sensors in the semicircular canal are triggered by the stones, which causes a feeling of dizziness.
