Breastfeeding in women with polycystic ovarian syndrome, gestational diabetes, and pre-existing diabetes: hormonal physiology, breastmilk composition, epidemiology and patient factors

多囊卵巢综合征和糖尿病（既存或妊娠）是孕妇的重要疾病。我打算探索（通过主要的文献综述和原始研究）它们如何影响母乳的生产和成分，这与没有条件的妇女有何不同，以及对婴儿健康的影响。我还旨在从激素（基础科学）的角度和更广泛的（人口）水平来研究这些妇女哺乳困难的原因。

Polycystic ovary syndrome and diabetes (pre-existing or gestational) are important conditions in pregnant women. I intend to explore (through major literature reviews and original research) how they influence the production and composition of breastmilk, how this differs from women without the conditions, and impacts on infant health. I also aim to examine reasons for lactation difficulties in these women, both from a hormonal (basic science) perspective and at a broader (population) level.
