In this episode, HeHe sits down with Dr. Kristin Lasseter to unpack perinatal mental health with a focus on postpartum anxiety (PPA) versus postpartum depression (PPD), how they differ, and when “baby blues” may signal something more. While mood shifts are common in the early postpartum days, symptoms that persist beyond a couple of weeks, disrupt sleep, bring constant anxiety or sadness, intrusive thoughts, or thoughts of death deserve real support.
They talk candidly about the guilt, shame, and fear of judgment that keep many women silent, and why telling one safe person can be a powerful first step. The conversation explores common risk factors like fertility struggles, pregnancy or birth complications, and PMDD, along with the significant hormonal shift that happens after the placenta is delivered and why the brain can feel especially vulnerable during that window.
HeHe and Dr. Lasseter also navigate the often-stigmatized topic of psychiatric medication during pregnancy and postpartum. They discuss why abruptly stopping medication is usually unsafe, how to thoughtfully weigh medication risks against the risks of untreated mental illness, what research tells us about breastfeeding compatibility, and what to expect when starting or adjusting treatment. They touch on newer, faster-acting postpartum depression options, therapy modalities like CBT and EMDR, and additional treatments such as TMS and ECT.
The episode closes with an honest conversation about bounce-back culture, social media pressure, and choosing support systems that protect a mother’s mental health. Throughout, the message is clear: evidence-based care matters, suffering in silence isn’t a badge of honor, and there is no shame in using medication when it’s needed.
