Failure to Thrive
What is failure to thrive?
Children are diagnosed with failure to thrive when their weight or rate of weight gain is significantly below that of other children of similar age and sex. Infants or children that fail to thrive seem to be dramatically smaller or shorter than other children the same age. Teenagers may have short stature or appear to lack the usual changes that occur at puberty. However, there is a wide variation in what is considered normal growth and development.
In general, the rate of change in weight and height may be more important than the actual measurements.
Infants or children who fail to thrive have a height, weight and head circumference that do not match standard growth charts. The person's weight falls lower than the third percentile (as outlined in standard growth charts) or 20 percent below the ideal weight for their height. Growing may have slowed or stopped after a previously established growth curve.
The following are delayed or slow to develop:
Physical skills, such as rolling over, sitting, standing and walking
Mental and social skills
Secondary sexual characteristics (delayed in adolescents)
It is important to determine whether failure to thrive results from medical problems or factors in the environment, such as abuse or neglect.
There are multiple medical causes of failure to thrive. These include:
Chromosome abnormalities, such as Down syndrome and Turner syndrome
Defects in major organ systems
Problems with the endocrine system, such as thyroid hormone deficiency, growth hormone deficiency or other hormone deficiencies
Damage to the brain or central nervous system, which may cause feeding difficulties in an infant
Heart or lung problems, which can affect how oxygen and nutrients move through the body
Anemia or other blood disorders
Gastrointestinal problems that result in malabsorption or a lack of digestive enzymes
Long-term gastroenteritis and gastroesophageal reflux (usually temporary)
Long-term (chronic) infections
Complications of pregnancy and low birth weight
Other factors that may lead to failure to thrive:
Emotional deprivation as a result of parental withdrawal, rejection or hostility
Economic problems that affect nutrition, living conditions and parental attitudes
Exposure to infections, parasites or toxins
Poor eating habits, such as eating in front of the television and not having formal meal times
Many times the cause cannot be determined.
The treatment depends on the cause of the delayed growth and development. Delayed growth due to nutritional factors can be resolved by educating the parents to provide a well-balanced diet.
If psychosocial factors are involved, treatment should include improving the family dynamics and living conditions. Parental attitudes and behavior may contribute to a child's problems and need to be examined. In many cases, a child may need to be hospitalized initially to focus on implementation of a comprehensive medical, behavioral and psychosocial treatment plan.
Do not give your child dietary supplements without consulting your physician first.
