A case report published in The Cureus Journal of Medical Science describes congenital chloride diarrhea that appeared before birth alongside polyhydramnios and preterm labor at 26 weeks of gestation. The report, dated October 1, 2026, covers both the prenatal and neonatal handling of the case.
According to The Cureus Journal of Medical Science, the pregnancy was complicated by polyhydramnios, a condition in which too much amniotic fluid builds up around the fetus, and by labor that began at 26 weeks. Congenital chloride diarrhea is a rare inherited condition that affects how the intestines handle chloride, leading to watery stools and, in newborns, a risk of dehydration and electrolyte imbalance.
The report focuses on how the condition was recognized before delivery and how the infant was managed after birth. The Cureus Journal of Medical Science frames the case as an example of prenatal and neonatal care working together when a rare disorder shows up during pregnancy.
Because the available summary does not include the patient's outcome, the specific treatments used, or the diagnostic steps in detail, those elements cannot be reported here. The case adds to a limited body of literature on congenital chloride diarrhea identified in the prenatal period, where polyhydramnios and early labor can be the first signs.
What to watch next: whether further case reports or studies clarify how often this condition presents with polyhydramnios and preterm labor, and what that means for earlier detection.
