Course of Pregnancies and Occurrence of Acute Pancreatitis in Women With Chylomicronemia

J Clin Endocrinol MetabPublished Retrospective cohort study

Authors' conclusion

In this study, pregnant women with chylomicronemia had a 30-fold (MCS) to 120-fold (FCS) higher occurrence of AP compared to the general population. Chylomicronemia per se does not seem to influence fetal development.
