Have you ever felt like the whole world was spinning when you got out of bed or turned your head to one side? It's normal to feel a little scared at times like that. In most cases, this can be caused by a condition called BPPV (Benign Paroxysmal Positional Vertigo), which we're going to talk about today. Although the name is a bit long, it's not a dangerous disease.
What is BPPV (Benign Paroxysmal Positional Vertigo)? Let's understand it simply.
Simply put, BPPV is a minor problem in our inner ear. What happens is that when you move your head in different directions, look up, get out of bed, or roll over in bed, you suddenly feel like the whole room is spinning (vertigo). It can feel like you're on a ship or on a spinning toy.
"Benign" means that this is not dangerous, not something like cancer. "Paroxysmal" means that this dizziness comes on suddenly, suddenly, and goes away after a while. "Positional" means that this occurs when the position of the head changes. "Vertigo" refers to that spinning sensation I mentioned. So, the name itself has a meaning, right?
Although BPPV is not a serious condition, its symptoms can be quite frightening. People over the age of 65 are at increased risk of falling, especially if they have this condition. If they do, they can even break their limbs (fractures). Therefore, it is important to be aware of this.
Who is more likely to develop BPPV?
Although BPPV can occur at any age, it is most common in people over the age of 50. In fact, it is said that about half of people in this age group will experience BPPV at least once in their lives.
BPPV is very rare in young children, but it can be seen occasionally.
How common is BPPV?
In fact, BPPV is a very common inner ear disorder. It's been found that only 20% of people who go to a doctor with vertigo actually have BPPV. That means if you're experiencing this, you're not alone.
If you develop BPPV, will it be permanent?
No, BPPV often goes away on its own . However, if it is not treated and controlled properly, it can come back. For some people, the vertigo can return months or even years later.
What are the symptoms of BPPV?
The main symptom of BPPV is a feeling that the world is spinning (vertigo). This spinning sensation can be mild or severe. It can last from a few seconds to a minute. It can be accompanied by other symptoms, including:
- Dizziness
- Lightheadedness, feeling like you're floating
- Loss of balance while walking or standing (Balance problems)
- Nausea and vomiting
- Blurred vision
- Rapid, continuous eye movements (Nystagmus) - Even if you don't notice this, a doctor can see it.
BPPV usually affects one ear at a time, but very rarely it can affect both ears.
What causes BPPV to suddenly appear?
BPPV often occurs when you change the position of your head. Some people may experience these symptoms when lying down or getting out of bed. Others may experience them when they tilt their head back or turn it to one side. As we age, the delicate parts of our inner ear wear down, so these symptoms can increase.
Sometimes, BPPV can be a symptom of another condition in the inner ear. For example:
- An infection or swelling of the inner ear (Labyrinthitis)
- Vestibular neuritis (swelling of the nerve related to balance)
- Acoustic neuroma, a non-cancerous tumor that develops in the ear
Additionally, people who have migraines can develop BPPV. Or, BPPV can develop after a strong blow to the head, for example, a fall, an accident, or another accident while playing sports.
Why do I get dizzy when I shake my head? What's going on inside this?
Okay, this is a bit of a scientific story, but let me put it simply. In our inner ear, there is a part that controls balance. It has a system of channels called the `Semicircular canals` . Also, close to these channels is another small organ called the `Utricle`.
Inside this `Utricle`, there are very small powder-like particles made of calcium carbonate `(Otoconia) .` Think of these as little `pebbles` in the ear. Normally, these `Otoconia` should be inside that `Utricle`.
However, sometimes due to injury, infection, or aging, some of these `Otoconia` (Otoconia) escape from the `Utricle` (Utricle) and go into those `Semicircular canals` (Semicircular canals). That's when the problem starts.
When you shake your head, the `Otoconia` that are inside those canals roll back and forth. Inside these canals are very fine hair-like parts `(Cilia).` These `Cilia` are what send information about balance to our brain. When those `Otoconia` roll and hit these `Cilia`, the brain gets a wrong signal, as if you are spinning. That's why you feel dizzy. Do you understand? It's like a little "short circuit" in the balance system in our ears.
How does a doctor diagnose BPPV?
When you go to a doctor, they will examine you, ask about your symptoms, and ask about your other medical conditions to determine if you have BPV. Sometimes, a special test (Dix-Hallpike test) may be done. In this test, the doctor will have you lie down on a bed and turn your head from side to side to check for dizziness and nystagmus.
Is there a way to cure BPPV quickly?
The best and quickest treatment for BPPV is physical therapy exercises. These exercises are called `Canalith Repositioning Procedures`. The goal of these is to move the `Otoconia` that are stuck in the `Semicircular canals` back to where they should be, the `Utricle`. Once there, the particles dissolve and are no longer a problem.
In addition to these exercises, you can take some motion sickness medications to reduce your dizziness. However, it is not advisable to take these medications continuously.
How do these BPPV exercises work?
These exercises, called ``Canalith Repositioning Procedures,'' usually take about 15 minutes to perform. In this, your head and body are manipulated one by one to reposition the misplaced ``Otoconia''.
Think of it like trying to get some small pebbles out of a bottle. You do this by turning the bottle from side to side. This exercise is like that.
One such exercise session will relieve about 80% to 90% of people with BPPV. However, if symptoms persist, you may need to do several more sessions.
Your doctor can show you these exercises. They can also teach you how to do them at home. Then you can do them whenever you feel dizzy.
Here are some simple exercise steps you can try at home (this is similar to the Epley Maneuver, but always consult a doctor ):
- Step 1: Sit upright in bed. Turn your head about 45 degrees toward the ear on the side that you are experiencing dizziness. (For example, if it is your right ear, turn to the right).
- Step 2: Quickly lie down in bed. Keep your head on the same side you turned, and lie down with your head slightly below the level of the bed (like sticking out of the corner of the bed). Wait for about a minute, or until your symptoms stop.
- Step 3: Without lifting your head, quickly turn your head to the other side. This means your "good" ear should now be parallel to the bed, slightly below. Hold for about a minute, or until the symptoms stop.
- Step 4: Roll over to the other side. Turn your head another 90 degrees in the same direction. Your nose should now be facing the floor. Hold for about a minute.
- Step 5: Keep your chin tucked to your chest and stand up on the same side as your body. Then follow the rest of the instructions given by the doctor.
Important: It's best to have someone with you when doing these exercises, as they may cause dizziness. Never do these exercises alone without a doctor's approval, especially if you have a neck problem.
Does BPPV get better on its own?
Yes, BPPV often goes away on its own. However, it can come back. If it does, your doctor will teach you how to manage your symptoms.
Can the risk of developing BPPV be reduced?
Unfortunately, BPPV cannot be completely prevented. However, you can manage the symptoms by doing the `particle repositioning exercises` I mentioned. To reduce the risk of BPPV from head injuries, don't forget to wear a helmet when riding a bike or playing contact sports.
What to expect if you have BPPV?
The good news is that BPPV is not a sign of a serious health problem. However, living with these symptoms can be a bit scary and annoying. Your doctor can teach you how to do BPPV exercises at home, so you can control it at the first sign of trouble.
How long can BPPV last?
Most of the time, the vertigo caused by BPPV lasts for 1 or 2 minutes. Your symptoms may be very mild, or they may be so severe that you vomit. You may lose your balance while standing or walking and fall.
When should I see a doctor?
If you have vertigo due to BPPV, see a doctor for advice. He or she will teach you physical therapy exercises to help reduce your symptoms.
However, if you experience dizziness along with a severe headache, chest pain, or an irregular heartbeat, call 911 immediately or go to the nearest hospital. These could be signs of another serious condition.
A few important words to understand about BPPV
To better understand what we've been talking about, let's learn a little about these parts of our inner ear:
- Semicircular canals: These are like a gyroscope in our head. They have channels in all three directions: up, down, and horizontally. Together, these channels send signals to our brain about the position of our head (e.g., when you are walking, turning).
- `Cupula`: This detects the flow of fluid inside the semicircular canals. This flow of fluid is what gives our body the sense of movement.
- `Utricle`: This is also an organ in the inner ear that helps control balance. It contains fine hair cells, which are covered with `Otoconia`. When these `Otoconia` oscillate with gravity, they send signals to the brain about the position of the head and body (such as upright or tilted).
- `Otoconia`: These are the tiny calcium crystal particles I mentioned earlier. These break away from the `Utricle` (where they can dissolve) and go into the `Semicircular canals` (where they don't dissolve).
- Cochlea: This is the "snail shell"-shaped hearing organ in our inner ear. It converts sound into nerve impulses and sends them to the brain.
Finally, things to remember (Take-Home Message)
BPPV is not a life-threatening condition, but it can have a significant impact on your quality of life. If you have symptoms of BPPV, such as sudden dizziness, vertigo, or loss of balance, you should see a doctor. In most cases, physical therapy exercises and home remedies can help control your symptoms. Don't panic, but be aware of this.
