Nonorganic failure to thrive.

Inadequate growth of children, or failure to thrive, can stem from organic or nonorganic causes. Factors involved in nonorganic failure to thrive include poor parental interaction with the child and inadequate caloric intake. Diagnosis of nonorganic failure to thrive requires a thorough history, physical examination, developmental assessment and careful dietary history, with less emphasis on laboratory testing. Therapeutic intervention consists of correcting the nutritional status and addressing the psychosocial issues.
