Failure-to-Thrive

En Espaol (Spanish Version)

Definition

Failure-to-thrive is a term used to describe a child who is not growing as expected. But, it is not the same as normal growth in a child who is small for his or her age. The exact definition is not completely agreed upon.

In general, failure-to-thrive means that a child:

  • Is at or below the 3rd to 5th percentile for height and weight, or
  • Has failed to grow as expected, as shown by dropping two growth percentiles (For example, the child goes from the 75th percentile to below the 25th percentile.)

Types include:

  • Organic failure-to-thrivecaused by some other medical condition
  • Nonorganic failure-to-thriveoccurs in children with no known medical condition
  • Mixed failure-to-thriveoccurs when the child has features of both organic and nonorganic failure-to-thrive

Endocrine disease Thyroid problemsPituitary diseaseDiabetesGrowth hormone deficiency Infectious disease HIVBacteria or parasites of the gastrointestinal tractTuberculosisChromosomal birth defectsFetal alcohol syndromeLead poisoningCancerPovertyChild abuse or negligenceParental ignorance Risk Factors A risk factor is something that increases your chance of getting a disease or condition.

The doctor will plot a child's weight, height, and head circumference on standard growth charts. If the child falls below a certain weight range or drops two percentiles on the growth chart, the doctor will evaluate the child further. If a medical condition may be the cause, the doctor will order further tests. Tests may include:
Blood testsUrine testsBlood lead levelHIV testThyroid testsSweat-chloride test Gastrointestinal x-raysX-rays of the gastrointestinal tract, skeletal survey, bone age Sometimes, a child must be hospitalized for a period of time to find the cause of failure-to-thrive. During this time the doctor will: Monitor the relationship between parent and child, paying particular attention to their behavior around feedingSet up a feeding schedule with an adequate amount of caloriesMake sure that an appropriate feeding technique is usedIf the child can gain weight under these circumstances, this supports the diagnosis of nonorganic failure-to-thrive. TreatmentTreatment may include: Treating a Medical ConditionTreating the underlying medical condition may correct failure-to-thrive. Providing Extra CaloriesChildren who are malnourished may need liquid supplements to help boost their weight and nutrition. Parent TrainingWhen a child is hospitalized for diagnosis, the hospital staff can also provide treatment. Nurses can teach parents appropriate feeding techniques and how to best interact with their child. If the child isn't hospitalized, parents can still have training sessions with a nutritionist or a nurse. CounselingParents and children who are having difficulty with their relationship may benefit from counseling.
