Pica was an unusual problem. A few of the patients I took care of during my thirty-year nursing career experienced it. Essentially, Pica is consumption of non-food items. Ice, clay, dirt, chalk are among common substances I have known patients to eat. Constant ice-eating can lead to anemia. I even knew of one patient who snitched a bag of clay from another patient who had dug it from a clay bank near her home. Afterward, the clay bank lady began peddling her bags of clay to other patients. The cause of Pica is poorly understood. It may arise from dietary deficiencies or cultural influences. There is no effective treatment, though patients are usually prescribed multivitamins. I did once have a patient who came in complaining of severe belly pain. During surgery, she was found to have eaten enough clay that it had hardened like a brick. She was totally obstructed and ended up with a temporary colostomy.
