Urine Osmolality and Fluid Intake in Pregnancy: Impact of Pre-Pregnancy BMI on Fluid Balance and the Need for Optimized Hydration Guidelines
Objectives: Maintaining adequate fluid intake during pregnancy is crucial for maternal and fetal health, yet limited research suggests a risk of hypohydration. This study assessed longitudinal urine osmolality (UOsm) and total water intake (TWI) across all trimesters, examining pre-pregnancy BMI as a potential modifier.
