Understanding Pica
When cravings go beyond food — eating non-food substances.
What Is Pica?
Pica is a condition where a person persistently eats non-food substances such as clay, chalk, paper, hair, or ice.
It's more common in children, during pregnancy, and in people with intellectual disabilities, but can affect anyone.
Common Substances
Ice (pagophagia) — often linked to iron deficiency.
Dirt or clay (geophagia).
Paper or cardboard.
Hair (trichophagia).
Paint chips.
Starch or cornflour.
What Helps
Medical evaluation is important — pica is often linked to nutritional deficiencies, especially iron and zinc.
Treating the underlying deficiency often resolves the cravings.
Behavioural therapy can help when pica is habitual.
Environmental modifications to limit access to harmful substances.
Addressing any underlying developmental or psychological conditions.
Regular monitoring for complications (bowel obstruction, poisoning, dental damage).
