Hello dear, Though eating of crushed ice may not cause you any acute health issue per se (except may be episodic headache or common cold), it can be a feature of an underlying pathological condition. The continuous craving for eating such inedible substances is known as Pica. It is one of the features of Iron deficiency anemia. Given the history that your family has a history of anemia from mother s side, it further substantiates the diagnosis. Investigations like complete blood count & peripheral blood smear will be helpful in assessment of degree of anemia. Based on the reports, management will include administration of supplemental Iron & Folic acid preparations. There can be associated factors like hookworm infection which needs to be managed with Albendazole preparations. Also you need to take a healthy balanced diet rich in green leafy vegetables. So, kindly consult your General Physician for proper clinical evaluation. Wishing you a good health. Take care.
