Pica

Pica is an eating disorder in which a person compulsively eats non-food items that have little or no nutritional value, such as soil, chalk, clay, paper, soap, hair, ice, or other non-food items. The behaviour is often present for at least one month and is clinically noteworthy when it is out of keeping with the person’s developmental level or cultural traditions. Pica can affect children, adolescents and adults but is most commonly diagnosed in childhood.

The reason for pica isn’t always obvious. It could be related to nutritional deficits, notably low iron or zinc levels. Psychological, developmental, and environmental factors also contribute. Some people may have pica as well as intellectual difficulties, autism spectrum disorder, or other mental health disorders.

Depending on what is ingested, pica can lead to serious consequences. These can include intestinal blockage, constipation, poisoning, infections, tooth damage, and nutritional difficulties. Contaminated substances can also introduce a person to dangerous bacteria, parasites, or hazardous chemicals.

Treatment depends on the underlying cause and may include nutritional examination, correction of deficiencies, behavioural therapy and psychological support. Working out your triggers and building safer ways of eating can help, too. Early assessment is critical since long-term use of non-food chemicals may pose serious health hazards.
