Benign Paroxysmal Positional Vertigo (BPPV)

BPPV results when crystals inside the inner ear shift into the wrong position. BPPV causes episodes of vertigo (spinning). Episodes most often occur when the head is moved in a certain way.

Infection or Inflammation


Meniere’s Disease

Meniere’s disease happens when there is too much fluid in the semicircular canals. This causes vertigo. It also causes hearing problems and buzzing or ringing in the ears (called tinnitus). You may also have a feeling of pressure or fullness in the ear.



Other Causes


  • Anxiety: Being anxious can lead to breathing changes, such as hyperventilation. These can lead to dizziness and fainting.
