Vertigo can be a frightening and uncomfortable experience. People who have vertigo often feel as if the room is spinning around them, even when they are standing still.
This sensation can cause dizziness, nausea, loss of balance, and difficulty walking. One of the most common causes of vertigo is a condition called benign paroxysmal positional vertigo, usually shortened to BPPV.
BPPV happens when tiny crystals inside the inner ear move out of place. The inner ear helps control balance and tells the brain how the head is moving. When these crystals shift into the wrong part of the ear, they send confusing signals to the brain. As a result, a person may suddenly feel that they or their surroundings are spinning.
Episodes of BPPV often occur when the head changes position. For example, symptoms may appear when someone lies down, rolls over in bed, tilts their head back, or bends forward. The spinning feeling usually lasts less than a minute, but it can still be very unsettling.
Although BPPV is not usually dangerous, it can greatly affect daily life. Some people experience repeated attacks that come back again and again over months or years. These repeated episodes can increase the risk of falls, especially in older adults.
Researchers have been looking for ways to reduce how often vertigo returns. A new study from scientists at Chungnam National University suggests that a simple approach may help. The research found that taking vitamin D and calcium supplements may lower the chance that BPPV will come back.
The study was led by Seong-Hae Jeong and colleagues and was published in the medical journal Neurology. The researchers wanted to see whether improving vitamin D levels in people with BPPV could reduce the risk of future vertigo episodes.
Vitamin D is an important nutrient that supports many parts of the body. It helps the intestines absorb calcium and phosphorus from food, which are essential for building strong bones. Vitamin D also helps keep the level of calcium in the blood stable and supports healthy muscle function.
Calcium and vitamin D work closely together. Calcium helps build and maintain bones, while vitamin D ensures that the body can absorb calcium effectively. Without enough vitamin D, the body cannot use calcium properly.
Scientists believe these nutrients may also influence the tiny crystals in the inner ear that are responsible for balance. Because these crystals contain calcium, changes in calcium metabolism may affect how stable they are. This idea led researchers to investigate whether vitamin D and calcium supplements could help prevent vertigo from returning.
In the study, researchers analyzed medical data collected from eight hospitals between December 2013 and May 2017. The study included patients who had been diagnosed with BPPV.
The participants were divided into two groups. One group received treatment with vitamin D and calcium supplements, while the other group was simply observed and received routine medical follow-ups.
People in the treatment group were given vitamin D at a dose of 400 international units and calcium carbonate at 500 milligrams. They took these supplements twice each day for one year. However, the supplements were only given to patients whose vitamin D levels were below 20 nanograms per milliliter at the start of the study, which is considered a low level.
The observation group did not receive extra vitamin D testing or supplements. Instead, these patients continued their usual medical care and follow-up visits.
At the end of the study period, the researchers compared how often vertigo returned in the two groups. The results showed a clear difference.
Patients who took vitamin D and calcium supplements experienced fewer repeated episodes of vertigo compared with those who did not take the supplements. In other words, the recurrence rate of BPPV was lower among people who received the vitamin treatment.
These findings suggest that improving vitamin D levels and ensuring enough calcium intake may help stabilize the balance system in the inner ear.
The researchers believe this approach may be especially helpful for people who frequently experience vertigo or who have low vitamin D levels. Because vitamin D deficiency is common in many parts of the world, correcting this deficiency could provide a simple and low-risk way to reduce vertigo recurrences.
The study also highlights the importance of maintaining adequate levels of key nutrients for overall health. Vitamin D supports bones, muscles, and balance, while calcium plays a critical role in the structure of bones and other tissues.
Although the results are encouraging, the researchers note that further studies could help confirm the benefits in different populations and determine the best doses for preventing vertigo.
Even so, the research suggests that a simple combination of vitamin D and calcium may offer a practical strategy to help people who suffer from repeated vertigo attacks. For many patients, ensuring proper nutrition and addressing vitamin deficiencies could make a meaningful difference in reducing future episodes and improving quality of life.
