Isolated fetal echogenic bowel and iron-rich mineral water supplement: a case series and review of the literature.

Natural iron-rich mineral water (IRMW) is a supplement with a higher iron bioavailability than oral iron supplement tablets. Five (4%) of 116 women who consumed IRMW starting from 16 weeks of gestation were diagnosed as having isolated foetal echogenic bowel at a single community maternity clinic between 2012 and 2015. The workup of all the women was otherwise negative.
