Official title
Evaluation of Fetal Cardiac Functions in Fasting Pregnant Women
Overview
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.
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.
