why do you crave ice when your iron is low

Possibly. Doctors use the term "pica" to describe craving and chewing substances that have no nutritional value such as ice, clay, soil or paper. Craving and chewing ice (pagophagia) is often associated with iron deficiency, with or without anemia, although the reason is unclear. At least one study indicates that ice chewing might increase alertness in people with iron deficiency anemia.


Less commonly, other nutritional problems may cause you to crave and chew ice. And in some individuals, pica is a sign of emotional problems, such as stress, obsessive-compulsive disorder or a developmental disorder.


A thorough medical evaluation can help determine if pica is due to an underlying medical condition. If the cause of pica is an emotional or developmental issue, cognitive behavioral therapy may be helpful. March 09, 2018
Anemia is a condition where your body does not have enough healthy red blood cells moving through your blood.


Without enough iron in your body, red blood cells cannot carry oxygen around efficiently, and the tissues in your body begin to suffer from this decreased oxygen supply. Iron deficiency anemia can occur for several reasons. Most commonly, iron deficiency occurs because of bleeding in the body, such as with excessive menstrual bleeding and bleeding in the digestive tract.


It can also occur in people with intestinal conditions such as Crohnвs disease or celiac disease, which might block iron absorption. People lacking enough iron-rich foods can also suffer from a deficiency.
