Benign positional vertigo is the most common type of vertigo. Vertigo is the feeling that you are spinning or that everything is spinning around you. It may occur when you move your head in a certain position.
Vertigo - positional; Benign paroxysmal positional vertigo; BPPV: dizziness- positional
Benign positional vertigo is also called benign paroxysmal positional vertigo (BPPV). It is caused by a problem in the inner ear.
The inner ear has fluid-filled tubes called semicircular canals. When you move, the fluid moves inside these tubes. The canals are very sensitive to any movement of the fluid. The sensation of the fluid moving in the tube tells your brain the position of your body. This helps you keep your balance.
BPPV occurs when a small piece of bone-like calcium breaks free and floats inside the tube. This sends confusing messages to your brain about your body's position.
BPPV has no major risk factors. But, your risk for developing BPPV may increase if you have:
- Family members with BPPV
- Had a prior head injury (even a slight bump to the head)
- Had an inner ear infection called labyrinthitis
