Feeling that the world is spinning or that you will lose your balance is a frightening experience many go through. This "vertigo" may be brief or recurrent and bothersome, and most of its causes trace to the inner ear responsible for balance. The ClinicsJo Editorial Team offers this guide to understanding vertigo, its causes, and treatment.
Vertigo vs. Dizziness
Vertigo is a false sense that the surroundings are spinning or that you are spinning, often linked to the inner ear. Dizziness is a broader term including unsteadiness, near-fainting, or light-headedness, and may relate to blood pressure, anemia, or other causes. Distinguishing them matters for diagnosis.
How Does Vertigo Happen?
The inner ear contains the balance organ (vestibule) that sends signals to the brain about head position and movement. When this system malfunctions or its signals conflict with the eyes, a person feels vertigo and loss of balance.
Common Causes
- Benign paroxysmal positional vertigo (BPPV): the most common, caused by tiny crystals moving in the inner ear, triggered by head-position changes.
- Vestibular neuritis: sudden severe vertigo often after a viral infection.
- Meniere disease: vertigo episodes with tinnitus, hearing loss, and ear fullness.
- Vestibular migraine.
- Other causes: low blood pressure, anemia, certain drugs, and less common neurological problems.
Associated Symptoms
- A sense of spinning or tilting.
- Loss of balance and difficulty walking.
- Nausea and vomiting.
- Tinnitus or hearing loss (in some causes).
- Sweating and pallor.
How Is It Diagnosed?
- Clinical exam, balance and eye-movement tests.
- Diagnostic maneuvers (such as the Dix-Hallpike test for BPPV).
- Hearing tests and sometimes imaging to exclude neurological causes.
Treatment
- Repositioning maneuvers (such as the Epley): very effective and quick for BPPV.
- Medication to ease vertigo and nausea in acute attacks (short term).
- Vestibular rehabilitation: specialized exercises to retrain balance.
- Treating the cause: such as Meniere disease or migraine.
Medical tip: BPPV — despite its frightening intensity — is among the easiest vertigo types to treat, resolved by a simple maneuver the doctor performs in minutes. Do not tolerate recurrent vertigo without diagnosis.
When to See a Doctor
See a doctor for recurrent or severe vertigo. Seek urgent care if vertigo comes with a sudden severe headache, facial or limb weakness, slurred speech, or double vision — possible signs of a neurological emergency.
Frequently Asked Questions
Is vertigo dangerous?
Most causes (especially ear-related) are not dangerous and are treatable, but a few cases may indicate a neurological problem needing urgent evaluation.
Does BPPV recur after treatment?
It can recur in some people, but the treatment maneuver is effective and can be repeated.
To diagnose and treat the cause of vertigo, book with an ENT doctor on ClinicsJo.
