đ Progesterone After Pregnancy: The Hormone We Donât Talk About Enough
After delivery, hormones donât simply âgo back to normal.â Progesterone and estrogen fall dramatically after the placenta is delivered, while prolactin may remain elevatedâespecially with breastfeeding.
That rapid hormonal shift is a normal part of postpartum physiology, but for some women, the postpartum transition can come with significant symptoms.
Low or fluctuating reproductive hormones may contribute to:
⢠Anxiety or feeling unusually on edge
⢠Irritability or mood changes
⢠Difficulty sleepingâeven when the baby is sleeping
⢠Feeling overwhelmed or emotionally sensitive
⢠Changes in libido
⢠Headaches or migraines
⢠Changes in menstrual cycles as they return
Progesterone is particularly interesting because its metabolite allopregnanolone interacts with GABA-A receptors in the brain, which are involved in calming and regulating the nervous system. In fact, medications that act on this same neurosteroid pathway are now FDA-approved specifically for postpartum depression.
That doesnât mean every postpartum woman needs progesterone supplementation. Postpartum depression and anxiety are complex, and treatment should be individualizedâespecially during breastfeeding.
But it does mean postpartum hormone changes deserve to be taken seriously.
⨠Postpartum care should be about more than one 6-week checkup.
Sleep, mood, thyroid function, iron status, breastfeeding, nutrition, mental health, and hormonal recovery can all be important pieces of the picture.
If you donât feel like yourself after having a baby, you deserve to be heardâand evaluated as a whole person. đ
