Dizziness, particularly when described as vertigo, is a sensation of spinning, movement, or loss of balance that can make a person feel unsteady or lightheaded. Vertigo often results from disturbances in the inner ear or vestibular system, which helps control balance, and may be caused by conditions such as benign paroxysmal positional vertigo (BPPV), inner ear infections, Meniere’s disease, or vestibular neuritis. Other forms of dizziness can stem from low blood pressure, dehydration, anemia, anxiety, or neurological disorders. Symptoms may include nausea, vomiting, imbalance, blurred vision, or difficulty concentrating. Because dizziness can have many underlying causes, persistent, severe, or recurrent episodes—especially when accompanied by weakness, confusion, or chest pain—should be medically evaluated.
