Everyone knows that ears are for hearing, but did you know that your ears are also responsible for balance? When you stand up quickly and feel light-headed, your ears are to blame. Read on to learn how healthy ears control balance, plus the causes and treatments of vertigo.
What is Vertigo?
Vertigo is dizziness caused by problems with the inner ear, the brain, or sensory nerve pathways. Symptoms include:
- Feeling dizzy and off balance.
- Feeling like you are spinning or like the world is spinning around you.
- Swaying or feeling pulled to one side.
- Nausea and vomiting.
- In some cases, ringing in the ears.
Usually, the cause of vertigo is a problem in the inner ear.
The inner ear is the innermost part of your ear and is a series of semicircular canals plus the cochlea. The cochlea is an essential component in your hearing pathway. It converts sound pressure patterns into electrochemical pulses that pass to the brain through the auditory nerve.
The vestibular system is a sensory system of three semicircular canals that come together near the cochlea. It sends signals to your brain about your altitude, linear movement, and head and body movement. The system detects your body’s position through fluids and fine, hair-like sensors inside your ear.
What is BPPV?
BPPV, or benign paroxysmal positional vertigo, is one of the most common forms of vertigo.
BPPV develops when calcium carbonate crystals, also called otoconia, shift and become trapped in the semicircular canals of the inner ear. Otoconia occur naturally in the ear and dissolve over time when they land in the utricle, a portion of the inner ear near the semicircular canals. Unlike the utricle, the semicircular canals cannot dissolve otoconia. Instead, the otoconia roll over the cilia, which are hair-like structures in the inner ear that send signals to your brain about your balance.
Tilting your head up and down, standing up, and sitting down may cause the otoconia to move across the cilia, causing bouts of dizziness.
BPPV is often episodic and recurring, but the actual dizziness comes and goes quickly. While BPPV is uncomfortable and unpleasant, it’s not usually a significant problem. The primary danger with this type of vertigo is the risk of falling or bumping into objects.
The specific cause of BPPV is unknown in most people. In some cases, it may be due to head impacts, migraines, or extended time laying on your back. It is most common in people aged 50 and over, but it can present in people of any age. It is more common in women than in men.
Other Causes of Vertigo
BPPV is the most common cause of vertigo, but dizziness can also be from:
- Meniere’s Disease – An inner ear problem caused by fluid buildup in the ear. The pressure changes from the fluid cause vertigo symptoms, and it can also be accompanied by tinnitus (ringing in the ear).
- Vestibular Neuritis or Labyrinthitis – Dizziness caused by an infection. The inflammation from the infection affects the ear nerves that control balance.
- Less common causes of vertigo are head and neck injuries, brain issues such as strokes and tumors, some medications, and migraines.
When to See Your Doctor
If your vertigo is sudden, severe, or lasts for long bouts, if you experience recurring dizziness over a long time, or if your symptoms do not go away on their own, make an appointment with your doctor.
When you experience vertigo, keep yourself safe by sitting as soon as you begin to feel dizzy. Use a cane when you walk if your episodes are frequent or prolonged and turn lights on when you get up during the night.
Your family practice doctor may refer you to an ENT (ear, nose, and throat) specialist, or you can schedule an appointment with Excel ENT directly.
The form of treatment depends upon the cause of vertigo. Often, time is the best treatment because vertigo usually resolves on its own. Your brain is incredibly adaptable, so it can compensate for inner ear issues and rely on other bodily mechanisms for balance.
For severe or persistent cases of vertigo, your doctor may treat you through:
- Vestibular Rehabilitation – A form of therapy that strengthens your vestibular system. This form of treatment is for recurring vertigo. It trains you to use your other senses to compensate for inner ear issues.
- Canalith Repositioning – A series of head and body movements that treat BPPV. Your doctor or audiologist will guide you through a few positions that will dislodge the calcium deposits from the canal and move them into the inner ear chamber so your body can reabsorb them. You’ll hold each position for approximately 30 seconds before moving to another position. Vertigo usually resolves itself over time, so canalith repositioning isn’t always necessary. However, it can dramatically shorten your healing.
- Surgery – If the vertigo is due to a brain tumor or a head injury, surgery may be necessary.
What Do I Do if My BPPV Comes Back?
For some people, BPPV will come back over time. You can make another appointment with your doctor or audiologist, or you can do the canalith repositioning yourself at home. A few treatments are all that it takes to dislodge the calcium crystals and alleviate your symptoms.
