pica
Pronunciation: PIE-kah
Craving and consumption of non-food substances during pregnancy, such as starch, ice, or dirt.
Full Definition
Pica is an eating disorder characterized by persistent craving and consumption of non-food substances for at least one month. In pregnancy, pica affects approximately 25-30% of women and commonly involves substances such as ice (pagophagia), starch (amylophagia), cornstarch, laundry detergent, clay, or dirt. While the exact cause is unknown, pica is often associated with iron deficiency anemia, though the relationship is complex and bidirectional. Pica can pose risks including nutritional deficiencies, dental problems, gastrointestinal obstruction, and toxicity from consumed substances. Healthcare providers should screen for pica sensitively and address any underlying nutritional deficiencies while providing counseling about safer alternatives.
Usage
Usage note: Always assess for underlying nutritional deficiencies when documenting pica.
