Pica is an eating disorder in which one feels a strong urge to eat non-nutritive substances like soil clay chalk charcoal paint paper soap glass hair ice etc. These cravings are most common in pregnant women and children. Some women develop pica for medicinal purposes. But the most common cause of pica is possible nutritional deficiencies (vitamin and mineral deficiencies). One of the most widely postulated causes of clay and dirt pica is iron-deficiency anaemia. Pica could be life-threatening for the mother and the child if the cravings are non-food items or dangerous items like dirt or paints and solvents.
