Researchers hypothesize that pregnancy and lactation are part of a continuum, with lactation meant to "reset" the adverse metabolic profile that develops as a part of normal pregnancy, and that when lactation does not occur, women maintain an elevated risk of cardio-metabolic diseases. Several large prospective and retrospective studies, mostly from the United States and other industrialized countries, have examined the associations between lactation and cardio-metabolic outcomes. Less evidence exists regarding an association of lactation with maternal postpartum weight status and dyslipidemia, whereas more evidence exists for an association with diabetes, hypertension, and subclinical and clinical cardiovascular disease.

哺乳期和母亲的心脏代谢健康。

研究人员推测，怀孕和哺乳是一个连续体的一部分，哺乳意味着“重置”正常怀孕期间出现的不良代谢状况，而当不发生哺乳时，女性患心脏代谢疾病的风险会升高。几项大型前瞻性和回顾性研究（主要来自美国和其他工业化国家）研究了哺乳期与心脏代谢结果之间的关联。关于哺乳与母亲产后体重状况和血脂异常之间关系的证据较少，而更多证据表明与糖尿病、高血压、亚临床和临床心血管疾病有关。
