Common Causes of Dizziness

In our earlier blog “Dizziness,” we discussed how dizziness can manifest in different patients, and what system in a person’s body maintains a sense of balance. But what are the root causes of dizziness? Like many symptoms, dizziness can be a symptom of a more serious medical issue, so it’s important to visit your ENT if you suffer from persistent dizzy spells.

Dizziness can be a symptom of high or low blood pressure, heart problems, stroke, a tumor, metabolic disorders or a side effect of certain medications. Other common causes include:
Acoustic Neuroma

This benign growth is located on the nerve connecting the inner ear to the brain. Your doctor may choose to monitor the growth of the neuroma, or they may recommend surgery to remove it.

Benign Paroxysmal Positional Vertigo (BPPV)

BPPV usually resolves in a matter of days, and typical causes short, sudden bursts of dizziness (usually as a result of quick head movement). There is no known cause of BPPV, but it occurs when small calcium crystals loosen and travel to the wrong part of the ear.

Inflammation of the Inner Ear

An inner ear infection could be the cause of dizziness. This is usually treated with antibiotics or anti-inflammatory medication.

Meniere’s Disease

Dizziness from Meniere’s disease usually lasts repeatedly for periods of thirty to sixty minutes, or more. It often also causes ringing in the ears, hearing loss, and a feeling of fullness in the ear. While there is no known cause or cure for Meniere’s disease, medication and behavioral changes can manage the symptoms.


Vestibular migraines have been known to cause vertigo and feelings of imbalance. They may also include hearing loss or ringing in the ears. Migraine-related vertigo can occur at the same time as the migraine, or separate from it.

As you can see, these conditions range from easily treatable to more serious. If your dizziness is at all repetitive or continuous, be sure to contact your doctor at Alexandria Otolaryngology Associates to determine the right treatment path for you.
