Summary

This study looks at how breastfeeding changes cholesterol and heart disease risk in women with familial hypercholesterolemia (FH), a genetic condition causing high cholesterol. Researchers will follow 50 pregnant women with and without FH from late pregnancy to one year after birth, collecting blood and breast milk samples. The goal is to understand if breastfeeding affects their heart health, which could guide future care.
