In our ear, more specifically in a structure called the vestibule, are calcium carbonate crystals called otoliths. Their role? To help the body detect movement and maintain balance. They work in conjunction with sensory hairs, much like position sensors.
But sometimes, these crystals move to places they shouldn't. As a result, the brain receives conflicting information, and you feel like the room is spinning when everything is actually still. This is called benign paroxysmal positional vertigo (or BPPV).
Why do these crystals move?
Several factors can contribute to this imbalance:Head trauma: a fall or impact can dislodge the crystals.
Aging: with age, these structures become more fragile.
Certain ENT infections: these can disrupt the balance system.
Medications: some drugs influence calcium metabolism.
Calcium or vitamin D deficiency: our diet also plays a key role!
