Possible Causes of Failure to Thrive

If stools are unusual, it might be useful to have the stool examined for evidence of a malabsorption syndrome. If all of these studies come back normal, and a baby is still not growing, then a further round of tests, possibly including thyroid function tests, liver enzymes, ammonia, lactate, pyruvate, a sweat chloride test, urine organic acids and serum amino acids, and perhaps x-ray studies, would be indicated.

Every mom wants to make sure that her child is growing. This instinct runs strong and deep and is there for good reason. When growth is not proceeding apace, take steps to correct the problem or to discover its cause.
