Ep. 429: The Science Behind Intrusive Thoughts with Dr. Katayune Kaeni aka Dr. Kat
In this episode of The Birth Lounge, HeHe sits down with perinatal psychologist Dr. Kat to have the conversation we don’t have enough: the real, nuanced truth about mental health in pregnancy and postpartum.
They break down the full spectrum of perinatal mood and anxiety disorders, including postpartum depression, anxiety, OCD, PTSD, panic attacks, bipolar disorder, and postpartum psychosis. They cover what’s common, what’s urgent, and what deserves immediate support.
A major focus of this conversation is intrusive thoughts.
Dr. Kat explains that intrusive thoughts are incredibly common, especially postpartum. They are typically unwanted, distressing, and they don’t reflect your true desires. But when thoughts become frequent, graphic, intense, or begin to interfere with daily functioning (like avoiding holding your baby out of fear), that’s when it’s time to reach out for professional support.
HeHe shares personal examples and normalizes how sleep deprivation, hormonal shifts, stress, and identity changes can amplify anxiety and intrusive thoughts, while emphasizing that struggling does not mean you are broken.
They discuss:
How to tell the difference between common intrusive thoughts and something more serious
Why suicide is the second leading cause of death in the postpartum period
When therapy and/or medication are appropriate and valid tools
How to talk to your partner and loved ones about not feeling like yourself
Why reassurance alone may not be enough for severe anxiety or OCD
How to use resources like Postpartum Support International
The importance of proactive conversations during pregnancy
This episode is compassionate, evidence-based, and deeply validating.
If you have ever thought, “Why is my brain doing this?” or felt afraid to say your thoughts out loud, this conversation will help you understand what’s happening, and remind you that support is not weakness. It is care.
You deserve to feel safe in your own mind.
