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(既往或妊娠期)是孕妇的重要疾病。我打算探索(通过主要的文献回顾和原创研究)它们如何影响母乳的生产和组成，这与没有这种情况的妇女有什么不同，以及对婴儿健康的影响。我还打算从荷尔蒙(基础科学)的角度和更广泛的(人群)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.
