Summary

This study looks at whether measuring body water with a harmless device can help detect obstructive sleep apnea (OSA) in pregnant women with severe obesity. OSA is common but often missed in this group, and can be dangerous for both mother and baby. Researchers will enroll 52 women in their third trimester to see if body fluid distribution is linked to sleep apnea, potentially offering a simple screening tool.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could lead to a simple, non-invasive way to screen for sleep apnea in obese pregnant women, helping prevent complications.
What could go wrong: This is a small observational study, so results may not apply to all pregnant women. The link between body water and sleep apnea is still unproven in pregnancy.
