Geophagy is the intentional ingestion of earth, soil or clay and is a form of pica. This practice is not uncommon in the southern regions of the United States or provinces of Africa. It may be seen in pregnant or iron-deficient patients 3. Although geophagia may be seen in the context of a variety of different cultural or religious practices, it is also encountered in patients with behavioural disturbances or psychiatric disease 4.
