Pica is a psychological disorder characterized by a persistent craving to consume substances that are largely non-nutritive. The range of consumed materials can be broad, including biological substances like hair (trichophagia) or feces (coprophagia), natural elements such as ice (pagophagia) or dirt (geophagia), and a variety of chemical or manmade materials. The term 'pica' is derived from the Latin word for magpie, a bird known for its indiscriminate eating habits.

Classification and Symptoms

Pica is classified as a feeding and eating disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The primary characteristic is the recurrent consumption of non-nutritive substances for at least one month, which is inappropriate for the person's developmental level and not part of a culturally sanctioned practice.

Causes

The exact cause of pica is currently unknown. However, it has been associated with other mental health disorders, including developmental disorders, schizophrenia, and obsessive-compulsive disorder. Pica can also occur during pregnancy and in individuals with certain nutrient deficiencies, such as iron deficiency anemia.

Treatment

Treatment for pica often involves behavioral interventions, such as reinforcing non-pica related behaviors, providing alternative activities, and educating individuals about the potential harms of non-nutritive eating. In some cases, medication may be used to treat the underlying mental health disorder associated with pica.

Complications

Pica can lead to a range of complications, depending on the substance consumed. These can include gastrointestinal obstruction or perforation, infections, and toxicity from ingested materials.
