BPPV


Benign Paroxysmal Positional Vertigo

or

BPPV

What is it?

BPPV is an inner ear balancing problem that causes brief spinning sensation due to change in the position of head.

BPPV is an acronym that stands for and means: Beneficial (it is often not a serious condition), Paroxysmal (happens abruptly and briefly), Positional Vertigo (dizziness occurs by changes in head position like when you tilt your head up or down, lying flat, turning to the other side of the bed, or bending over)

How does BPPV happen?

Inner ear structure:

Each of our inner ear has 5 balance organs: 3 semicircular canals and 2 otolith organs (saccule and utricle) which contains tiny calcium carbonate crystals (otoconia) and are all connected by inner ear fluid.

Cause of BPPV

BPPV is caused by free floating crystals within the sensitive parts of inner ear. These crystals are made up of calcium carbonate. There is a structure within the inner ear called Otoconia made up of calcium carbonate crystals. The otolith organs are the organ which detect movements and transmit it to the brain, allowing us to determine which way is up, down, forward or backward. Sometimes minor injuries or sudden head movements can cause displacement of these crystals into the fluid inside the inner ear. These crystals will then float freely in the inner ear fluid and moves with the position of head. Moving your head in certain positions will cause these crystals to shift and travel inside the semicircular canal fluid to the posterior semicircular canal (The most common form, accounting for 81% to 90% of all cases).This may irritate the balance organs inside the inner ear and send out false signals to the brain causing vertigo

BPPV happens when some of the tiny crystals (otoconia) become loose and disconnected from their location, they will float freely in the inner ear fluid. When this happens moving your head in certain positions will cause these crystals to shift and travel inside the semicircular canal fluid to the posterior (The most common form, accounting for 81% to 90% of all cases). This causes the onion-shaped structure (known as the cupula), which provides our body’s sense of direction, to send incorrect signals to the brain, resulting in vertigo.

Symptoms

  • Dizziness/lightheadedness (vertigo)
  • Trouble with balance
  • Difficulty concentrating
  • Nausea (moderate to vomiting)

Very often, the symptoms go away and then come back weeks or months later. Without treatment, symptoms might continue for a few weeks before going away. For some people, the symptoms never come back after the first time.

Although BPPV can be bothersome, it's rarely serious. However, if it raises your risk of falling, please see your doctor.
