Catching your balance or perceiving the world is spinning can be both disconcerting and baffling. Dizziness and vertigo are phenomena shared by most individuals at some stage in their lives, yet they are confusing. Dizziness is an all-encompassing term—it can describe being lightheaded, unstable, or faint. Vertigo is more precise. It’s that odd, whirling feeling, like you or the space around you is turning even when you are perfectly motionless.
At the heart of our balance is the vestibular system—an intricate network inside the inner ear and brain that functions like our body’s internal gyroscope. It scans continuously for head and body motion and sends signals to enable us to stay balanced, know where we are in space, and orient ourselves. When this system is interrupted, either by disease or trauma, we may experience dizziness, vertigo, or both.
There are several reasons why one may feel dizzy or have vertigo. WebMD states that the majority of vertigo incidents are caused by problems with the inner ear. BPPV, Ménière’s disease, and vestibular neuritis are the usual causes. BPPV occurs when small crystals within the inner ear become dislodged and disrupt the signals your brain uses to balance you. Ménière’s disease is a buildup of fluid and pressure in the inner ear and may induce vertigo, hearing loss, and tinnitus. Vestibular neuritis or labyrinthitis—usually caused by viral infections—may cause inflammation of nerves that are responsible for balance.
But inner ear problems are not the sole reason. Dizziness also results from low blood pressure, medication side effects, dehydration, or even eye disorders. Occasionally, the cause is found in the brain. Stroke, tumors, or neurological disorders may disrupt the way the brain handles balance, resulting in worse or longer-lasting symptoms.
There is also a significant and frequently unseen connection between anxiety and dizziness. It is a two-way relationship. Dizziness can be caused by anxiety through mechanisms such as hyperventilation, which reduces oxygen levels to the brain, or a vasovagal reaction, in which blood pressure falls suddenly. Conversely, getting dizzy, and particularly doing so suddenly or unexpectedly, can make a person anxious or panicked. Medical News Today adds that individuals with anxiety disorders are at increased risk of developing certain forms of vertigo, and the anticipation of another episode of dizziness becomes a stressor in itself.
Symptoms associated with vestibular disorders can be quite variable. Aside from the spinning sensation that characterizes vertigo, individuals may have difficulty standing or walking, blurred vision, nausea, vomiting, tinnitus, or even difficulties concentrating. Some complain that they feel as though they’re being tugged in one direction, or that they’re swaying. Others can experience abnormal eye movements or a feeling of fullness in one ear. These symptoms may occur in short bursts or persist for hours or even days.
Determining what’s behind dizziness or vertigo requires time and a little detective work. Physicians may order a series of tests, beginning with a physical examination and monitoring closely the movement of your eyes. They might conduct specific maneuvers, such as the Epley maneuver, to determine if displaced crystals are the problem in instances of BPPV. If there is suspected brain difficulty, imaging such as MRI or CT scans may be required.
Treatment varies depending on the underlying cause. In most situations, vertigo will resolve by itself as the brain adapts. But when intervention is necessary, there are lots of choices. Vestibular rehabilitation therapy, a type of physical therapy, can retrain your brain and body to adjust and regain balance. Medications can be taken to alleviate nausea or to decrease swelling, and in some extreme cases, surgery is indicated. Small lifestyle modifications can also be of great help: remaining well-hydrated, rising slowly, reducing caffeine and alcohol intake, and employing breathing exercises to cope with anxiety or stress.
Having constant dizziness or vertigo can be draining, both physically and mentally. The lack of predictability of the symptoms may cause individuals to shun normal activities, resulting in social isolation or even depression. The Cleveland Clinic also mentions that vestibular conditions that are left untreated can lead to complications such as repeated falls, hearing loss, and excessive emotional stress.
Understanding how our body’s balance system works—and how closely it’s tied to our mental health—can be the first step toward relief. Whether your symptoms come from a physical issue, anxiety, or a mix of both, there are ways to get better. With the right diagnosis and a personalized treatment plan, many people can regain their balance and get back to living with more confidence and peace of mind.
