- Failure to thrive is defined as inadequate physical growth diagnosed by observing growth trends on standard growth charts.
- It can be classified as organic (caused by medical issues) or nonorganic (caused by psychosocial factors) and further divided into prenatal or postnatal categories.
- Evaluating a child for failure to thrive involves taking a thorough history including feeding and medical history, performing a physical exam, and ordering basic screening labs tailored to the child's history and exam findings.
- Treatment focuses on increasing caloric intake to promote catch-up growth, addressing any underlying medical issues, modifying feeding behaviors, and involving psychosocial support services if nonorganic causes are suspected.
