10 Causes of Dizziness
Cause #2: Inner Ear Problems
The inner ear contains calcium and protein-based sensing crystals called otoconia. When these crystals become dislodged and float in the inner ear canals, a person may experience a spinning sensation. The loose crystals cause vertigo because they are supposed to make you sensitive to gravity and help keep balance. This is called benign paroxysmal positional vertigo, or BPPV. It is possible to resolve this mechanical problem through physical therapy instead of medication or surgery. If you do experience BPPV, consider doing treatment at home with a series of body movements that reposition the crystals in your inner ear. Sit and turn your head 45 degrees to the right. Lie down on the left side and stay for 30 seconds. Return slowly to the seated position and wait a few minutes before doing the same on the opposite side.
This is a common inner ear-related balance disorder that affects 1 out of 1000 people each year, typically in older adults. It is usually for no apparent reason, however, trauma and infections may trigger this to occur.
The Dix-Hallpike test is primarily used to diagnose BPPV. During the test, you are placed in a position that causes vertigo. Then, the doctor checks for involuntary eye movements associated with BPPV. The test may be done in several ways to determine which side is causing the problem.
