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, including digit purpura (redness of fingers caused by twining the hair around them before pulling), musculoskeletal injury (e.g., carpal tunnel syndrome; back, shoulder, and neck pain), blepharitis (inflammation of eyelids), and dental damage (e.g., worn or broken teeth resulting from hair biting).
Swallowing of hair (trichophagia), which may lead to trichobezoars (hairballs), with subsequent anemia, abdominal pain, nausea, vomiting, bowel obstruction, and even bowel perforation.
