My baby is now four months old and I am still craving it. htmASKTHEDOCeatingchalkpregnancy The craving for chalk is most likely related to iron deficiency. The general medical term for craving certain items is "pica." With iron deficiency, you can have cravings other than chalk, including ice, paper, coffee grains and seeds. Its not known why iron deficiency causes pica. But once a person has replenished his or her iron stores, the craving disappears. 1440997 InteliHealth 2012-05-15 t Howard LeWine, M.D. 2015-05-15  | Ask The Expert | |  |  |  |  | | Archive By Date: Ask the Doc Q&A | Page 1 of 4 | | Answered questions from the past 2 years: | |  y 13-year-old daughter has been diagnosed with a hemangioma.
