Abstract:

Failure to thrive（FTT） is a condition commonly seen by primary care pediatrician. Many children with FTT are not identified unless careful attention is paid to plotting growth parameters at routine checkups. It is a signal of undernutrition.But the etiology of FTT is seldom the results of a single causative medical，genetic or socioeconomic factor. There is increasing recognition that in many children the cause is multifactorial and includes biologic，psychosocial，and environmental contributors. The prolonged malnutrition can negatively affect a child’s future growth and cognitive development and behavioral problem and learning difficulties are identified in a significant portion of FTT population. A thorough history and physical examination is the best guide to establishing the etiology of the FTT and directing further evaluation and management.The approach to nutritional rehabilitation in FTT requires individualization. Prompt multidisciplinary interventions are important for preventing malnutrition and developmental sequelae.
