Pica

Pica is a psychological disorder characterized by an appetite for substances that are largely non-nutritive, such as ice, clay, paper, chalk, or dirt. The term "pica" comes from the Latin word for "magpie," a bird known to eat almost anything.

Causes and Risk Factors

The exact cause of pica is not fully understood, but it is believed to be linked to several factors, including:

• Nutritional deficiencies, particularly iron deficiency
• Pregnancy
• Mental health conditions, such as autism spectrum disorder, intellectual disability, and schizophrenia

Diagnosis

Pica can be diagnosed through a combination of physical examination, medical history, and laboratory tests. A healthcare provider may:
