The human inner ear consists of the cochlea and the vestibule, with the cochlea being responsible for hearing and the vestibule having three sets of semicircular canals responsible for balance. For people with sensitive vestibular function, dizziness may occur when walking or exercising, or when they are prone to motion sickness or seasickness, or when they are prone to dizziness when riding in amusement parks or rotating facilities, or even when they have gastrointestinal symptoms such as nausea or vomiting, or when they have otoliths or Meniere’s syndrome and are walking or exercising and become dizzy. This is the time to go to the hospital to test the vestibular function and let the ENT doctor help diagnose what is causing the problem.
