i just randomly stumbled upon this thread and thought i'd throw out the warning...
My mom has an ice pica and has had it for a few years now. She was slightly anemic before she started up with the ice eating, but it made it MUCH much worse... so much so that she just got out of the hospital because she needed a blood transfusion because her iron and hemoglobin levels were dangerously low.
She makes about 8 trays of ice a day - typically likes to eat after a meal as well...
the doctor has pretty much forbidden her from eating ice now.
please dont take this warning lightly... She is in a VERY serious state due to her ice eating. hopefully the blood transfusion will help with her dependency.
