Treatment
Treatment depends on the cause of the delayed growth and development. Delayed growth due to nutritional problems can be helped by showing the parents how to provide a well-balanced diet.
Do not give your child dietary supplements such as Boost or Ensure without talking to your provider first.
Other treatment depends on how severe the condition is. The following may be recommended:
- Increase the number of calories and amount of fluid the infant receives
- Correct any vitamin or mineral deficiencies
- Identify and treat any other medical conditions
The child may need to stay in the hospital for a little while.
Treatment may also involve improving the family relationships and living conditions.
Outlook (Prognosis)
Normal growth and development may be affected if a child fails to thrive for a long time.
Normal growth and development may continue if the child has failed to thrive for a short time, and the cause is determined and treated.
Possible Complications
Permanent mental, emotional, or physical delays can occur.
When to Contact a Medical Professional
Contact your provider for an appointment if your child does not seem to be developing normally.
Prevention
Regular checkups can help detect failure to thrive in children.
