Vertigo isn’t just dizziness; it’s the unsettling feeling that you or your surroundings are moving when they aren’t. Roughly 40% of people experience this at some point, but the sensation is often misunderstood. It’s more than just lightheadedness; it disrupts balance and can significantly impact daily life.
What Causes Vertigo?
Vertigo arises from a problem in your inner ear or the brain’s balance systems. There are two main types: peripheral vertigo, the more common form, which stems from issues within the inner ear itself, and central vertigo, a rarer occurrence linked to brain problems like infections, injuries, or strokes. Researchers are also investigating a third form related to head movements and severe motion sickness.
Recognizing the Symptoms
Symptoms vary widely. Peripheral vertigo often presents with dizziness, vision problems, hearing loss, tinnitus (ringing in the ears), and nausea. Central vertigo, however, can include more severe signs like double vision, difficulty swallowing, facial paralysis, slurred speech, and limb weakness. These sensations are often worse when standing, walking, or moving your head, and can last from minutes to months.
Risk Factors and Underlying Conditions
Certain factors increase your likelihood of experiencing vertigo. Women over 50 with a family history of the condition or a history of head injury or osteoporosis are at higher risk. Underlying medical issues can also play a role, including Ménière’s disease (fluid buildup in the ear), neuronitis (inflammation of the vestibular nerve), migraines, and even stroke.
Diagnosis and When to Seek Help
Diagnosing vertigo can be tricky because symptoms are subjective. Doctors will likely start with a physical exam and may order imaging tests like CT scans or MRIs to pinpoint the cause. Hearing, vision, and blood tests may also be used. If symptoms are frequent or severe, or if they accompany chest pain, severe headache, vision changes, or limb weakness, seek immediate medical attention.
Treatment and Prevention
Many cases resolve on their own within days, but chronic vertigo may require treatment. For benign paroxysmal positional vertigo (BPPV), head-positioning exercises can help. Other treatments depend on the underlying cause. Falling is a significant risk with vertigo, especially for older adults, so fall prevention measures are crucial.
Vertigo is a symptom, not a disease. It’s a signal that something is off balance in your body, and understanding the cause is key to finding relief. If vertigo is interfering with your daily life, consult a doctor to get a proper diagnosis and treatment plan.
