Overview
Pica is defined as the compulsive craving for or eating non-nutritive or non-food substances for at least a period of one month[1]. Pica maybe a part of a cultural phenomenon, during childhood, in persons or children who are mentally disabled or even in pregnancy. Iron deficiency anemia is also an important cause of pica. Pica is treated by a multifocal approach which includes reduction of cravings, addressing the social and emotional issues faced by the individual and treating the anemia if present. Pica is further divided based on the type of substance ingested such as ice, lead, feces, soil etc.

Obtain a detailed history: ❑ Duration of symptoms ❑ What is the substance being ingested? ❑ When does the patient exhibit this behaviour? ❑ Is it during periods of emotional or physical stress? What is the source of the substance? According to the DSM5, the following 5 criteria must be met to diagnose someone with pica[3]: ❑ Person must be eating non-nutritive or non-food substances for at least one month. ❑ This behaviour must be considered abnormal for their stage of development. ❑ This behaviour must not be considered as a part of a cultural practice, and should be normal in the social context of that person. ❑ For a person with an existing condition like mental disability or pregnancy, this behaviour is considered as pica only when it is dangerous or requires medical investigations and attention. | |||||||||||||||||||||||||
