Child Eating Lint: Causes (Pica, Teething, Anxiety), Risks, and Management

Persistent ingestion of non-food items (lint, dirt, paper) is called pica. Possible drivers:

• Nutritional deficiency: Iron, zinc, calcium (most common).
• Developmental: Teething (oral soothing), sensory exploration.
• Psychological: Anxiety, stress, autism spectrum, OCD.
• Imitation/attention-seeking.

Risks

• Choking/aspiration
• GI obstruction/bezoar
• Toxicity (dyes, chemicals, lead in old fibers)
• Infection (bacteria, parasites)
• Dental wear

Management

1. Medical eval: CBC, ferritin, zinc, lead level; developmental screen.
2. Environmental control: Lint traps, vacuum frequently, keep laundry out of reach.
3. Nutritional correction: Iron/zinc supplementation if deficient.
4. Behavioral: Redirect to safe chewables (teething toys, crunchy veggies); positive reinforcement for appropriate behavior.
5. Therapy: CBT, habit reversal, sensory integration OT if neurodevelopmental.

Most childhood pica resolves with treatment of underlying cause. Persistent cases need multidisciplinary care.
