failure to thrive
A condition in which a child's growth and weight gain fall significantly below expected ranges for their age and sex.
Full Definition
Failure to thrive (FTT) is a clinical condition characterized by inadequate physical growth in infants and children, typically defined as weight below the 3rd percentile for age or crossing two major percentile lines on standard growth charts. The condition can result from organic causes (medical conditions affecting nutrition absorption or metabolism), non-organic causes (inadequate caloric intake due to feeding difficulties or psychosocial factors), or mixed etiologies. Early identification and intervention are crucial for preventing long-term developmental consequences. Assessment includes comprehensive medical history, physical examination, growth chart analysis, and evaluation of feeding practices and family dynamics.
Usage
Usage note: Distinguish between organic and non-organic causes in documentation. Avoid using as a diagnosis without specifying underlying etiology.
