Overview, Causes, & Risk Factors
Failure to thrive, also known as FTT, occurs when an infant ortoddler fails to gain weight and grow in a healthy manner. In some cases,the child may even lose weight.
What is going on in the body?
Usually discovered in infants and in children younger than2 years, failure to thrive describes a child’s lack of steady growth. It mayrefer to body weight and also to inadequate growth in height and headcircumference.
FTT is generally classified as:
Most infants between 6 months and 1 year of age stopgrowing as rapidly as they did during the first few months of life. They will continueto eat well yet show no decrease in activity or development. Caregiversshould not mistake this healthy slowdown in growth for FTT.
What are the causes and risks of the condition?
The causes of FTT vary and are not always obvious. Certaindiseases or physical conditions can cause inadequate weight gain such as:
A child may not be adequately fed if there is a bonding orbehavioral problem between the parent and child. Some infants may havedifficulty expressing hunger, a poor appetite, or intolerance for some foods.This makes feeding them harder, especially for a new parent.

If a doctor does not have a diagnosis after the history,physical, and laboratory evaluation, he or she may order further studies. A feedingevaluation, usually done by an occupational therapist, can rule out thepresence of a subtle feeding disorder. A psychological and social serviceevaluation of the family may also be in order.
Prevention & Expectations
What can be done to prevent the condition?
For some parents, a child’s failure to gain weight at a steady rate isobvious. Other parents may not recognize the signs and symptoms as easily.That’s why it’s important for an infant to be seen by a healthcare providerevery few months during the first year. The provider will chart the progress of growth.It would be helpful for parents or caregivers to be educated on infant care.Offering support systems to caregivers may also help prevent non-organiccauses of failure to thrive.
What are the long-term effects of the condition?
Rarely, the infant may die of malnutrition. In severe cases,children may show signs of:
What are the risks to others?
FTT poses no direct risk to others. If the cause of FTT is aphysical condition, the child may require extra medical care, which canbe a burden on family members. If the cause is environmental, the caregiversmay need guidance.
Treatment & Monitoring
What are the treatments for the condition?
If the underlying cause is organic, treatment for that disorderoften brings about healthy growth. To determine if the FTT cause is organic,the infant may be hospitalized and fed under controlled conditions. Insome cases of FTT, feedings may be given through a stomach tubethat is passed through the nose into the stomach. In extreme cases,a gastrostomy feeding tube is placed through the abdominal wall into thestomach.
If the infant thrives and gains weight, the cause may not beorganic. The hospital setting also allows professionals to observe how theparent interacts with the child. If the cause is thought to be environmental,a social service evaluation may also be done to offer support to the caregivers.
What are the side effects of the treatments?
If surgery is needed to place a gastrostomy tube throughthe abdominal wall into the stomach, possible side effects includeallergic reaction to the medicationsused during surgery or infection at the site of surgery.
What happens after treatment for the condition?
The outcome depends on the underlying cause of the FTT.Infants with specific physical disorders may need lifelong treatment forthe underlying disorder. Counseling and support may also prove usefulfor infants who fail to thrive because of feeding disorders or parental neglect.
How is the condition monitored?
The child’s healthcare provider should provide ongoingfollow up not only of the physical growth, but of the child’s cognitiveand psychosocial development to assure continued progress andprovide further intervention where needed. Any new or worsening symptomsshould be reported to the healthcare provider.
