Prompt: Failure to thrive (FTT) or weight faltering is commonly used to describe a lack of adequate weight gain in pediatric patients. Accepted definitions include a weight for age less than the fifth percentile on standardized growth charts, a decrease in weight percentile of more than 2 major percentile lines on the growth chart, or less than the 80th percent of median weight for height/length ratio. Given the many causes of FTT, clinicians must obtain a thorough history and physical exam. Healthcare professionals should recognize that inpatient management has a role if the patient is more severely malnourished, has other underlying conditions, or has failed outpatient management. FTT is essential to recognize and treat because it can result in developmental delays and other long-term effects for the developing child. As the underlying reason for FTT is often related to inorganic etiologies of inadequate caloric intake, leveraging an interprofessional team, including nutrition, behavioral health, and social workers, can be especially helpful when caring for pediatric patients with FTT. This activity reviews the evaluation and management of FTT and highlights the role of the interprofessional team in the care of patients with this disorder.
