Causes of PPD are varied, but some important ones to mention include the erratic changes of hormone levels in the body that contribute to sleep deprivation, exhaustion, and physical discomfort. Genetics may also play a role leaving some to be more vulnerable than others to PPD. Societal pressures that demand mothers to “bounce back” to their prenatal bodies and prenatal self only exacerbate PPD. Lack of support, whether it be emotional, financial, or in everyday challenges, can also play a part in the severity of PPD.
