Failure To Thrive

Failure to thrive (FTT) is a medical term used in both pediatric and adult human medicine, as well as veterinary medicine (where it is also referred to as ill thrift).

When not more precisely defined, the term refers to pediatric patients. In MeSH, the term is assumed to refer to an infant or child. In children, it is usually defined in terms of weight, and can be evaluated either by a low weight for the child’s age, or by a low rate of increase in the weight.
