Treating Vertigo: Balancing Fluid in the Ear
How to Reverse Your Inner Ear DizzinessPeter is a young man in his mid-forties without any health issues. He has three children, and he and his wife have been married for over twenty years. His job isn’t unusually stressful. He plays tennis every week, and has no problem keeping up with the ball. However, he came into the office with several months of dizziness and nausea. It comes and goes, and seems to happen mostly at night when he lies down, or in the morning when he wakes up. Sometimes dizziness will wake him up at night. He can work all day, including exercise without any symptoms.
Vertigo is often confused with dizziness. Let’s look at all the different types of dizziness.
- Dizziness – the general term for feeling movement when there is none.
- Lightheadedness – what we feel when standing up too fast; a “head rush.”
- Giddiness – the sensation you get when you are at the top of the Empire State Building, and you look straight down.
- Presyncope – the feeling of almost passing out, usually including vision and hearing changes, or numbness and tingling.
- Disequilibrium – a lack of strength or stability from peripheral muscles and nerves.
- Anxiety – panic, a sense of impending doom.
- Vertigo – a specific feeling of spinning or movement in a certain direction, such as after being on a merry-go-round, and continuing to feel the spinning after stopping.
One of the problems is that these symptoms can overlap, so there isn’t a way to distinguish them well.
There are two primary types of vertigo.“Peripheral” or a problem with the fluid balance in the ear.
- “Central” or a problem with the nervous system, like the brain.
A sensation of spinning can happen from the “vestibular system” in the inner ear. This is an amazingly tiny system of three circular canals that have fluid in them. As the fluid moves, a signal is sent to the brain that the body is moving.
This tiny sensory apparatus is absolutely brilliant in its simplicity and effectiveness! There are three little tubes in a circle that are oriented in three different directions. One is up-down, another is side-to-side, and the third is front-back.
Thus, any direction you move will cause the fluid inside the tubes to move. The fluid then moves a cluster of little sand crystals that push against hairs attached to nerve fibers that send a signal to the brain: “We’re moving in this direction!”
There are many different sized hairs in each – longer hairs trigger easier, while shorter hairs require more pressure. Thus, we can know if there is a little movement, or a lot. Moreover, the combination of impulses from the three canals can indicate any direction.
However, when the tiny amount of fluid in these canals changes and you are not moving, your brain still registers motion. When it happens in only one canal, it is usually a feeling of spinning. This is vertigo.
The best way to tell if vertigo is from the inner ear is if the sensation happens with a specific movement. Typically, someone might say, “Every time I turn to the left, I feel like I just got off a merry-go-round.” It may take anywhere from seconds to several minutes for the sensation to diminish or go away.
A note about nausea…some people get nausea when they have sensations of movement and they aren’t moving. This is the basis for seasickness and other motion sickness. On the boat, everything looks stable so the eyes are sending a message of no movement. But the inner ear, the vestibular system, is telling the brain that you’re moving. This conflict often results in sickness. Some people are very sensitive to the eye-ear connection, and others can tolerate more conflict.
Thus, when some people get even tiny amounts of vertigo, even riding a roller-coaster, Ferris wheel, or merry-go-round, it can elicit nausea and vomiting. Some people with vertigo will do anything to stop it because they feel sick every time it happens. Thus, they will only turn their heads very slowly, or only in one direction.
Causes of Peripheral Vertigo
Anything that changes the nature or movement of the fluid in the inner ear can cause peripheral vertigo. This fluid is connected to the “cochlea” or the organ that translates sound waves into nerve impulses. Peripheral vertigo can be caused by:
- Loud noises that vibrate the fluid in the inner ear, producing a sensation of movement.
- Inflammation of any kind changes the nature and amount of fluid in the canals, or affects the crystals.
- Injury from head and neck trauma or tumor growths can create vertigo symptoms.
- Viral infections, such as herpes, or shingles are common, causing fluid shifts and inflammation.
- Bacterial infections such as syphilis were a common cause of peripheral vertigo, but are now rare since we use antibiotics.
- Fluid shifts – the balance between the cells that make the fluid and the ones that reabsorb it.
- Changes in the vestibular apparatus, such as plugging of the canal with calcium deposits, or the calcium crystals sticking together. It is thought that sometimes the crystals get “stuck” against the hair trigger of a nerve, causing it to be jammed in the “on” position.
Of course, the treatment of vertigo will depend on the cause. The most common cause called BPPV or Benign Paroxysmal Positional Vertigo seems to be caused by a displaced crystal in the inner ear. The treatment for this is called “Epley Maneuvers,” named after the doctor who developed it. These movements intend to relocate
