Dizziness is a general feeling of being off-balance or lightheaded – you may feel woozy or as if you might faint. Vertigois a specific kind of dizziness – a false sensation that you or your surroundings are spinning.
Common Symptoms
Dizziness and vertigo can show up in a few different ways. You may experience:
- Spinning sensation: A feeling that you or the environment is spinning or tilting.
- Lightheadedness: Feeling faint, woozy, or as if you might pass out.
- Loss of balance: Difficulty staying steady on your feet, which can lead to staggering or falls.
- Nausea or vomiting: An upset stomach or vomiting often accompanies more intense vertigo.
- Ear-related issues: Ringing in the ears (tinnitus) or muffled hearing, especially when inner ear problems are the cause.
These symptoms can be alarming, but noting when and how they happen will help with diagnosis. Pay attention to what triggers your dizziness (such as standing up quickly, turning your head, or being in certain positions) and any other symptoms that occur with it. This information helps the doctor figure out whether the cause is likely in the inner ear, the brain, or elsewhere.
Causes of Dizziness and Vertigo
There are many possible causes. Typically, they are divided into two categories: peripheral causes (issues in the inner ear or vestibular nerve) and central causes (issues in the brain or nervous system).
Peripheral Causes (Inner Ear)
Peripheral vertigo results from problems in the inner ear balance system. Common examples include:
- Benign Paroxysmal Positional Vertigo (BPPV): Brief, intense spinning episodes triggered by certain head movements, caused by tiny calcium crystals shifting into the wrong part of the inner ear.
- Vestibular neuritis (labyrinthitis): A sudden, severe vertigo attack due to inflammation of the vestibular nerve (often from a viral infection). It can last hours or days and may be accompanied by nausea and, if the inner ear is involved, some hearing loss.
- Meniere’s disease: An inner ear disorder involving fluid buildup. It causes episodes of vertigo along with ringing in the ear, a feeling of fullness, and fluctuating hearing loss.
Central Causes (Brain)
Central vertigo is dizziness originating from the brain or nerve pathways. Common examples include:
- Migrainous vertigo: In some people, a migraine attack triggers vertigo even if there’s no severe headache. The vertigo can last minutes to hours and may include sensitivity to light or sound.
- Stroke or TIA: A stroke or transient ischemic attack in the balance centers of the brain can cause sudden vertigo and loss of balance. It often comes with other symptoms like double vision, difficulty speaking, or weakness in part of the body.
Dizziness can affect anyone, but certain factors increase the risk. Older adults, people with a history of migraines or inner ear disorders are more prone to vertigo. Anxiety can also trigger dizzy spells.
