title: Glucose metabolism disorders and vestibular manifestations: evaluation through computerized dynamic posturography.
abstract: BACKGROUND
  Global sugar consumption has increased in the past 50 years; its abusive intake is responsible for peripheral insulin resistance, which causes the metabolic syndrome - obesity, diabetes mellitus, hypertension, and coronary heart disease.
  
  
  OBJECTIVE
  To evaluate the effect of a fractionated diet without glucose as treatment for labyrinthine disorders associated with glucose-insulin index.
  
  
  METHODS
  The study design was a prospective randomized controlled trial. Fifty-one patients were divided into two groups: the diet group (DG), which comprised subjects treated with a fractionated diet with glucose restriction, and the control group (CG), in which individuals were not counseled regarding diet. Patients underwent computerized dynamic posturography (CDP) and visual analog scale (VAS) on the first and 30th days of the study.
  
  
  RESULTS
  There was improvement in the assessed posturographic conditions and VAS self-assessment in the DG group after 30 days when compared to the control group.
  
  
  CONCLUSIONS
  The fractionated diet with glucose restriction was effective for the treatment of vestibular dysfunction associated with glucose metabolism disorders.
