The main reasons for postpartum depression occur because, after childbirth, there is a sharp change in hormone levels in women, which often leads to the development of postpartum depression. Additionally, aside from hormonal changes, there are also psychological changes in women after childbirth. Women may struggle with poor adaptation postpartum, as well as a lack of clear role identification and acceptance, leading to contradictory emotions that they find difficult to manage under normal stress. This situation is prone to lead to depression. Moreover, women tend to be physically weaker after childbirth, experiencing fatigue and physical discomfort, which can also affect their emotional state. Furthermore, the lack of care from family members or the husband can make it more likely for postpartum depression to occur.
