Dizziness and vertigo are similar conditions that may strike without warning. However, there are some differences between the two.
With dizziness, you have a sense of light-headedness or may feel faint. You may feel as though your head is spinning and may feel disoriented. Your balance may also be affected, increasing risk of injury.
Dizziness often remains unexplained, but can be caused by ear problems or can be a side effect of medication. Dizziness can also be a consequence of a heart or brain condition or of advancing age.
Vertigo produces a sensation of spinning, whirling or turning. Many people experiencing vertigo feel that the room is actually moving and have difficulty standing or walking.
Headaches, such as migraines, may be a cause of vertigo. Positional vertigo may occur when you move your head quickly and can result in nausea, vomiting, imbalance and light-headedness. Other known causes are Meniere's disease, vestibular neuritis, perilymph fistula and inner ear disease.
It is important to see your doctor for correct diagnosis and treatment of dizziness or vertigo. Medical treatment of the cause of the condition will often relieve the symptoms.
