TY - CHAP M1 - Book, Section TI - Poor Weight Gain A1 - Duryea, Teresa A1 - Motil, Kathleen J. A2 - Kline, Mark W. PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - Poor weight gain is the finding of weight loss or a deceleration in the rate of weight gain. Failure to thrive describes the condition of infants and toddlers under age 2 years who have an abnormally low weight relative to their stature for their age and sex. With prolonged and/or severe malnutrition, linear growth and head circumference can be secondarily affected. The term failure to thrive is not a singular disorder; rather, poor growth is a sign of an underlying problem that leads to insufficient usable nutrition. A wide variety of medical and psychosocial factors can contribute to poor weight gain.
