Vertigo is not necessarily fear of heights. In medical terms, vertigo refers to a false sensation of movement due to which we feel dizzy. The most common type of vertigo is Benign Paroxysmal Positional Vertigo or BPPV. It is caused when our inner ear which helps us maintain balance by detecting motion and position of our body, doesn't function properly.
Normally, when we move our head, the cilia and calcium crystals in our inner ear move, thus sending signals to the brain about our movement. However, sometimes some crystals dislodge and move into the fluid filled semicircular canals. Now, when we move our head, the crystals move along with the fluid. However, even after our head movement has stopped, the crystals keep moving in the canals, thus sending wrong signals to the brain that our head is still moving. Due to this wrong information, the person gets a false sensation of movement which makes him feel dizzy, thus causing vertigo.
