Vertigo is a condition that makes you feel like you or your surroundings are spinning or moving when they’re actually not.
It can be very unsettling and affect daily activities. To better understand this condition, let’s look at the common causes of vertigo, explained in simple language.
One of the most common causes of vertigo is called Benign Paroxysmal Positional Vertigo (BPPV). BPPV happens when tiny calcium particles, called canaliths, move into the inner ear canals.
The inner ear is responsible for sending signals to your brain about head and body movements relative to gravity. When these particles disrupt this process, it can cause a brief spinning sensation, especially when you move your head in certain ways.
Researchers believe that these particles can become dislodged due to head injury, prolonged bed rest, or aging.
Another cause of vertigo is Meniere’s disease. This condition affects the inner ear and is characterized by sudden episodes of vertigo, hearing loss, ringing in the ears (tinnitus), and a feeling of fullness in the ear.
The exact cause of Meniere’s disease is not known, but it is thought to be related to changes in the fluid in the inner ear. Researchers are investigating factors such as genetics, viral infections, and autoimmune responses as potential triggers for this condition.
Vestibular neuritis, also known as labyrinthitis, is another common cause of vertigo. This condition is caused by an inflammation of the inner ear, typically due to a viral infection.
The inflammation interferes with the transmission of sensory information from the ear to the brain, resulting in vertigo. People with vestibular neuritis often experience sudden, severe vertigo that can last for days, accompanied by nausea and balance problems.
Migraines can also cause vertigo, even without the headache that usually accompanies them. This is known as vestibular migraine or migraine-associated vertigo.
The exact link between migraines and vertigo is still being studied, but it is believed that the same mechanisms that cause migraine headaches, such as changes in blood flow and nerve cell activity in the brain, may also affect the balance centers of the brain, leading to vertigo.
Inner ear infections can lead to vertigo as well. Bacterial or viral infections that affect the inner ear can cause swelling and fluid buildup, which disrupts the balance signals sent to the brain. This type of vertigo usually comes on suddenly and may be accompanied by ear pain, discharge, or hearing loss.
Another possible cause of vertigo is head or neck injuries. Trauma to these areas can damage the inner ear or the nerves responsible for balance, leading to vertigo. Whiplash from car accidents, for example, can cause neck injuries that result in vertigo.
Less commonly, vertigo can be a symptom of more serious conditions such as stroke or multiple sclerosis (MS). A stroke that affects the brain areas responsible for balance can cause sudden and severe vertigo.
Multiple sclerosis, a disease that affects the central nervous system, can also cause vertigo if it damages parts of the brain or spinal cord that control balance.
In summary, vertigo has various causes, including Benign Paroxysmal Positional Vertigo (BPPV), Meniere’s disease, vestibular neuritis, migraines, inner ear infections, and head or neck injuries.
Less commonly, it can be linked to more serious conditions like stroke or multiple sclerosis. Understanding these causes can help in managing and treating vertigo effectively.
If you experience vertigo, it’s important to consult a healthcare provider to determine the underlying cause and appropriate treatment. By staying informed about the potential causes of vertigo, you can better navigate this challenging condition and seek the help you need to feel better.
