It is my understanding that undiagnosed celiac disease causes a predisposition of higher risk in the pregnant population: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9756025/
“Undiagnosed celiac disease is associated with a higher risk of adverse pregnancy outcomes. Early celiac disease diagnosis and appropriate management with GFD may ameliorate these associations.”
Good news for the pregnant mamas who are managing well.
