Geophagia: A case series.

Geophagia, a form of pica, is often associated with iron and zinc deficiency. However, a number of environmental, cultural, and psychological factors are also implicated. Pica in children is common with those having intellectual disability. In adults, it is most commonly associated with pregnancy. No specific screening tests for pica exist, but many nutritional and psychological complications can be avoided by accurate and timely diagnosis. Even when pica is diagnosed, no proven treatments exist. Two patients who reported to the psychiatry outpatient department with habit of eating nonnutritive substances for a prolonged period associated with apprehension and decreased appetite are reported. Both the patients were diagnosed with adult pica and were treated with selective serotonin-reuptake inhibitors and psychotherapy with considerable improvement.
