What is considered the primary cause of postpartum depression?

The primary cause of postpartum depression is largely attributed to a combination of hormonal changes and psychosocial factors. After childbirth, a woman's body undergoes significant hormonal fluctuations, particularly with hormones such as estrogen and progesterone experiencing dramatic reductions. These hormonal shifts can affect mood regulation and contribute to the onset of depression.

In addition to biological factors, psychosocial elements play a crucial role. The emotional and psychological adjustments to motherhood, including changes in identity, lifestyle, and expectations, can lead to feelings of overwhelm, anxiety, and sadness. Factors such as lack of support, sleep deprivation, and existing mental health conditions further compound these issues, making it essential to consider the interplay between biological and psychosocial influences when assessing the risk of postpartum depression. This understanding helps in identifying at-risk individuals and providing timely interventions that address both hormonal and psychological aspects.
