(HealthDay News) -- "Failure to thrive" occurs among infants who don't grow and gain weight as quickly as they should.

The Nemours Foundation mentions these possible causes of failure to thrive:

  • Parents aren't feeding babies enough food or frequently enough.
  • Medical conditions such as GERD, celiac disease or cystic fibrosis.
  • A physical abnormality such as a cleft lip that makes it difficult for a child to eat.
  • A medical condition, such as a cardiac, respiratory or endocrine disorder.
  • A milk protein intolerance.
  • An infection.
  • A metabolic disorder that affects how a baby breaks down and processes food.
