                                According to a 2015 meta-analysis, the global prevalence of pica in pregnant and postpartum women is estimated to be 23.0% in North and South America and 44.8% in Africa. The medical term for the behavior is pica, and the specific compulsion to eat rocks, soil, or clay is known as geophagy. This unusual craving can be a sign of underlying issues, from nutritional deficiencies to mental health conditions, and should not be ignored.
