Breastfeeding and Cardiovascular Health

Maternal LDL Reduction During Lactation

Lactation for ≥3 months improves maternal LDL cholesterol compared to no lactation or short-duration breastfeeding, resulting in a 14-21% reduction in coronary heart disease risk for women who breastfeed for at least 3 months 1, 2
The American Heart Association recommends exclusive breastfeeding for the first 6 months of life, with continued breastfeeding to at least 12 months with the addition of complementary foods, which aligns with both infant health benefits and maternal cardiovascular risk reduction 3, 5, 6

Breastfeeding is associated with an 11% reduced risk of overall cardiovascular disease, 14% lower risk of coronary heart disease, 12% reduced risk of stroke, and 17% reduced risk of fatal cardiovascular disease 1, 2
Long-term follow-up studies demonstrate that subjects who were breastfed as infants have sustained cardiovascular health benefits in adulthood, including lower cholesterol levels, lower BMI, reduced prevalence of type 2 diabetes, and lower carotid intima-media thickness 3

For women with elevated LDL cholesterol or cardiovascular risk factors, breastfeeding should be strongly encouraged as a non-pharmacologic intervention to improve lipid profiles 3, 5, 6
The American Academy of Pediatrics recommends exclusive breastfeeding for the first 6 months of life, with continued breastfeeding to at least 12 months with the addition of complementary foods, which aligns with both infant health benefits and maternal cardiovascular risk reduction 3, 5, 6
Statins must be discontinued during breastfeeding, as they are contraindicated during the lactation period 7

For women with diabetes or gestational diabetes, breastfeeding provides additional metabolic benefits, reducing the risk of developing type 2 diabetes by 32% (OR 0.68) 9
These women should receive specific counseling about maintaining adequate nutrition (minimum 1,800 kcal/day) and monitoring for hypoglycemia during nursing sessions 9, 10
