Let’s talk about DMER! 🤱🏽
DMER stands for Dysphoric Milk Ejection Reflex. It is characterized by intense feelings of negative emotions, anxiety, sadness, and sometimes nausea during the letdown. It can come with a “pit in the stomach” feeling, dread, or even irritability. The wave of symptoms are brought on by hormones and usually resolve within a few minutes (once the letdown passes). It can happen during any letdown which means those random phantom cries, the internal clock that says your baby should be hungry now, pumping, and any other scenario where your body is triggered to make milk flow can all come with DMER symptoms.
During a letdown, oxytocin levels surge while dopamine levels abruptly drop. This dip in dopamine triggers an immediate but brief emotional crash. This is not postpartum depression, postpartum anxiety, or a breastfeeding aversion, but can definitely co-exist and potentially worsen these issues.
DMER is not a reflection of your parenting or connection with your baby. It is very real, and the effects can be very hard to cope with. If you need support navigating DMER, a skilled IBCLC can help!
