Why this Study Matters
Many breastfeeding parents have questions about using weight-loss medications — but there’s very little research available.
This study aims to better understand:
- Whether newer weight-loss medications may be present in breast milk
- How these medications may affect infant growth
By participating, you’ll help close critical gaps in breastfeeding safety data and support evidence-based care for families and healthcare providers.
