What is failure to thrive?

Also known as: FTT, weight faltering, faltering weight

If an infant or child has a low body weight compared to other children of the same age/sex, is not maintaining or gaining weight at a normal rate, because of inadequate calorie intake, poor food absorption or increased caloric expenditure, the condition is known as failure to thrive. It may be related to a number of medical, behavioral and/or psychological problems.
