Pica is an eating disorder which is characterized by the repeated eating
of non-nutritive substances over a period of one month or longer. Patients
may eat non-edible objects such as paint, plaster, dirt, ice, or laundry
starch. Pica generally affects small children, pregnant women, and people
whose cultural environment is most compatible with the eating of non-food
items.
Symptoms
Onset of Pica is generally between 12 to 24 months of age. Infants typically
eat paint, plaster, string, hair or cloth. Older children may eat substances
such as animal droppings, sand, bugs, leaves or pebbles. Aversion to food is
absent. Complications of the disorder are lead poisoning (from eating lead-
based paints) and hairball tumors. Non-food items such as laundry starch,
clay, dirt, stones, chalk and limestone are other substances which may be
craved by Pica patients. Children usually outgrow Pica. Rarely adults may
manifest the disorder. Pregnant women sometimes have a craving for unusual
foods like pickles or ice and rarely non-food items.

Health Conditions/Concerns area of NORD Services.
Causes
While a relationship between Pica and iron deficiency has been suggested, a
cause and effect relationship has not yet been proven. Some substances which
are craved by patients with this disorder interfere with the body's
absorption of iron from food. Some authorities believe that Pica is a
learned pattern of behavior while others theorize that it is due to other
cultural, psychological and physiological factors or a combination of these
factors. In many cases, correction of iron or other deficiencies in the
patient may eliminate the abnormal craving which characterizes this disorder.
Affected Population
Pica can begin as early as the age of one year and is usually outgrown by six
or seven years of age, but some cases persist until puberty. Some adult
women, particularly pregnant women, can suffer from this disorder. Severely
retarded people often must be monitored to protect them from eating non-edible
substances.
Therapies: Standard
Treatment of Pica mainly consists of preventing patients from eating the
craved, non-nutritive substances. Psychiatric counseling aimed at behavior
modification is often recommended. However, for certain cultural reasons,
some Pica clay and starch eaters may persist in occasionally eating a lump or
two of these items.
When mineral imbalances can be identified in people who have Pica, the
imbalance should be corrected with vitamin and/or mineral supplements. In
many cases correction of these deficiencies will stop or reduce the craving
for inedible substances.
Therapies: Investigational
