What this trial studies

This observational study investigates the effects of maternal obesity, diabetes, and previous bariatric surgery on pregnancy outcomes. It compares pregnancies in women with normal BMI to those who are overweight or obese, as well as those with gestational or type 2 diabetes. The study will assess various maternal and fetal health parameters throughout pregnancy and postnatally, including biophysical and biochemical profiles. Participants will undergo a series of investigations at multiple gestational ages and post-delivery to gather comprehensive data on their health and pregnancy outcomes.
