Purpose of Review
Poor weight gain is a common presenting problem in pediatrics. We review literature supporting the notion that extensive workup is generally not needed, particularly in younger children and discuss a management approach depending on a patient’s age.
Recent Findings
Understanding normal growth, particularly in infancy, is important. Breastfed and formula-fed infants as well as older children have different etiologies for poor growth. Diagnostic workup and hospitalization are rarely indicated or useful. An attempt to increase energy intake is often the appropriate first step in management.
Summary
Poor weight gain can affect children of all ages. Understanding expected growth, common etiologies by age, and how to assess nutritional status can help with appropriate diagnostic workup and management.
