Vertigo is the most common type of dizziness. The most common diseases that result in vertigo are benign paroxysmal positional vertigo (BPPV), MÃ©niÃ¨re's disease, and labyrinthitis. Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, and migraines.
Vertigo and other types of dizziness also may be affected by blood circulation problems, possibly worsened by stress or heart trouble. Taking in large amounts of caffeine â lots of coffee, for example, or caffeinated soda or energy drinks â can constrict blood vessels and increase your vertigo symptoms.
