Study summary

In this study, we aimed to evaluate fetal cardiac functions after a fasting period of at least 10 days. The purpose of this study was to determine the unexpected effects of fasting on fetal cardiac functions.

Read the detailed description

Pregnancies at 24-34 weeks of gestation who present to our hospital for routine antenatal follow-up will be evaluated. As the study group, singleton uncomplicated pregnancies with at least 10 days of fasting will be assessed. All ultrasonographic examinations will be conducted within the last 2 hours of the fasting period. The control group will consist of healthy pregnant women who do not fast, with singleton uncomplicated pregnancies between 24-34 weeks, matched for age, parity, and gestational age.
