Pica:
Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))
Anemia (iron deficiency)
Chronic, severe iron deficiency anemia may cause pica for dirt, paint, cornstarch, nails, or clay (although controversy exists over whether pica is the cause or the result of the deficiency). Pica may also cause fatigue, irritability, listlessness,and anorexia. The patient may complain of light-headedness, headache, an inability to concentrate,dysphagia,and exertional dyspnea. His muscle tone is poor, and he may experience paresthesia in his extremities. His nails are brittle and spoon shaped, his tongue is smooth, and his skin and mucous membranes are pale.
Malnutrition
Severe malnutrition and starvation may cause pica for any substance, including dirt. Besides marked weight loss, the patient may develop muscle wasting and paresthesia in the extremities. He appears lethargic and apathetic. His skin is dry, thin, and flaky. His sparse, dull hair falls out easily. His nails are brittle, his cheeks are dark and swollen, and his lips are red and swollen. The patient may also experience nausea and vomiting, hepatomegaly, bradycardia, hypotension, slow and shallow respirations, and amenorrhea or gonadal atrophy.
Psychological disorders
Pica can occur with psychological disorders marked by profound impairment, such as schizophrenia and autism.
Cultural cue Pica is an accepted practice in some cultures, based on presumed nutritional or therapeutic properties or on religious or superstitious beliefs.
