What this trial studies
The MAMA study is a prospective cohort study that investigates how pancreas size changes during pregnancy in women and their infants, particularly focusing on the impact of maternal diabetes. It will follow pregnant women aged 18-54 who are under 14 weeks gestation and their babies through pregnancy and one year postpartum. Participants will undergo various assessments including MRI scans, blood tests, and glucose monitoring at multiple points during and after pregnancy to gather data on pancreas size and its relationship with gestational diabetes and infant development.
Why it matters
Potential benefit: If successful, this study could enhance understanding of gestational diabetes and improve maternal and infant health outcomes.
How similar studies have gone: While there have been studies on pancreas size and diabetes, this specific approach of monitoring changes during pregnancy is relatively novel.
