Functional Consequences of Trichotillomania (Hair-Pulling Disorder)

Functional consequences of trichotillomania may include:

  • Distress and social and occupational impairment
  • Irreversible damage to hair growth and hair quality
  • Infrequent medical consequences of trichotillomania including digit purpura (i.e., redness of fingers caused by twining the hair around fingers before pulling hair), musculoskeletal injury (e.g., carpal tunnel syndrome; back, shoulder, and neck pain), blepharitis (i.e., inflammation of eyelids), and dental damage (e.g., worn or broken teeth resulting from hair biting)
  • Swallowing of hair (trichophagia) may lead to trichobezoars (i.e., hairball), with subsequent anemia, abdominal pain, nausea and vomiting, bowel obstruction, and even bowel perforation
