I eat about 7 pounds of ice a week. is this unhealthy? i did have a problem with anemia but last blood test was normal. i've had the cravings 2 years

Maybe: People who eat ice, or starch or in some areas clay often have an iron deficiency problem. Though you said you had anemia which was now proved normal--you may still have a degree of iron deficiency, which can only be evaluated with specific blood tests--serum iron, per cent iron saturation and ferritin. If you have menstrual periods, you loose iron every month. Are you on vitamins with iron?

Possibly an issue: Craving ice, also known as pagophagia, is often associated with fedeficiency anemia or other nutritional deficiency state. It can also be a manifestation of a behavioral issue. A visit to your doctor can help sort through the details, arrive at a explanation and institute corrective measures as required. Feel free to chime in with additional details.
