  • Eroded enamel
  • Altered bite
  • Lost teeth
  • Contusions or lacerations of the oral cavity from the use of items to induce emesis
  • Pyorrhea
  • Highly Sensitive teeth resulting from gingival deterioration
  • An increase in dental caries


  • Hypochloremic metabolic alkalosis
  • Uric acid elevated
  • Low blood glucose
  • Elevated or depressed cholesterol

  • Acrocyanosis
  • Scars (such as on knuckles due to inducing emesis, vomiting)
  • Loss of subcutaneous tissues and fat in general
  • Fine lanugo hair (form of hair growth associated with malnutrition)


  • T-3 deficiency (leads to bradycardia, dry skin, cold intolerance, sluggish reflexes hypercarotenemia, and several hair abnormalities)
  • Addison’s disease or hyperaldosteronism
  • The inability to concentrate urine normally and partial diabetes insipidus condition
