New study aims to answer: is breastfeeding safe for moms with Wilson's disease?
NCT ID NCT05183165
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at copper levels in breast milk from women with Wilson's disease who are on treatment. Wilson's disease causes copper buildup, and treatment can lower copper, which might affect breast milk. The goal is to find out if breastfeeding is safe for their babies. About 20 pregnant women with Wilson's disease will provide milk samples after childbirth.
