What’s Blue Diaper Syndrome?

Blue diaper syndrome is a genetic disorder that affects the body’s ability to process tryptophan, causing blue urine and potential digestive, fever, and vision issues. Treatment involves a low-tryptophan diet, and the condition can only occur if both parents pass on the faulty gene.

Blue diaper syndrome is an inherited condition that causes people to have difficulty metabolizing tryptophan, an essential amino acid that plays an important role in the human diet. Due to the inability to process tryptophan, the urine becomes a characteristic pale blue. This condition is known as blue diaper syndrome because it usually occurs at a very early age and the distinctive bluish urine color is hard to miss.

In addition to turning urine blue, blue diaper syndrome can also cause more general digestive issues, along with fever and vision problems. In some cases, children with the condition also develop kidney disease, as the body struggles to metabolize tryptophan. The colored urine associated with blue diaper syndrome is caused by bacterial interactions in the gut, leading to the production of compounds that turn blue when exposed to oxidation.

This condition cannot be cured. The best treatment is to prescribe a low-tryptophan diet, with parents keeping a close eye on what their children eat. This amino acid is found in several meats, perhaps most notably turkey, along with sunflower seeds, eggs, milk, potatoes, sesame seeds, and some cheeses, among other things. Typically a doctor will discuss safe levels of tryptophan and foods that should be avoided when establishing a treatment plan.

Blue diaper syndrome is a recessive genetic disorder, which means someone must inherit two genes to develop symptoms. As a result, people can be carriers without even realizing it, until they meet other carriers and have children, at which point the condition will manifest if both parents pass on the faulty gene. Several mutated genes have been identified as the potential causative agents behind blue diaper syndrome, which may allow future researchers to prevent blue diaper syndrome from occurring in people who have both genes.

Like other metabolic disorders, blue diaper syndrome can become a serious problem if not addressed. Metabolism disorders can cause a wide range of health problems, some of which can become debilitating for the patient. As a general rule, the most notable syndrome of this condition is so unique that parents usually seek medical attention promptly, luckily avoiding complications before they arise.
