Pica is a condition in which a person craves substances that are
not food, such as clay, dirt, ice, or flecks of old paint. Pica can have a
physical cause, such as iron deficiency anemia or pregnancy, or it may be due
to a psychological problem.
Treatment depends on the cause and may include psychological
counseling or medications to reduce the craving.
