Tryptophan Malabsorption Overview
Another name for Tryptophan Malabsorption is Blue Diaper Syndrome.
What is blue diaper syndrome?
An infant with blue diaper syndrome is unable to absorb the amino acid, tryptophan, from the diet. Instead, bacteria break down the tryptophan into chemicals, which are then absorbed by the intestine. These chemicals pass into the urine and turn the urine blue. Blue diaper syndrome is a rare hereditary disease. An abnormal gene does not allow for the absorption of the amino acid, tryptophan.
What are the symptoms of blue diaper syndrome?
Common symptoms of blue diaper syndrome include vomiting, fussy infant, failure to thrive, poor weight gain, malnutrition, irritability, blue-tinged urine, fever, constipation, vision problems, and poor feeding in infants.
How does the doctor treat blue diaper syndrome?
Treatment for blue diaper syndrome includes a diet that is low in tryptophan.
