Dysphoric Milk Ejection Reflex: Report of Two Cases and Postulated Mechanisms and Treatment.

Abstract

Background: The symptoms of Dysphoric Milk Ejection Reflex (D-MER) occur just before milk release, last no more than a few minutes, and then subside spontaneously, which are characterized by a sudden and transient feeling of dysphoria, depression, sadness, or other negative emotions. These emotions may adversely affect the mother's lactation behavior and mental health, negatively influence the mother-child relationship, and even result in self-harm or suicidal tendencies in lactating women. Case Presentation: We reported two cases of breastfeeding mothers with D-MER who experienced unpleasant emotions during lactation. Severely affected by D-MER symptoms, the mother in the first case chose to wean prematurely after struggling for 6 months, and her symptoms disappeared after weaning. With the help of professional guidance, the mother with D-MER in the second case actively adjusted and persisted in breastfeeding until her daughter was 18 months old, after that her symptoms vanished. Discussion: Awareness and knowledge of D-MER are insufficient among the public and health care professionals. D-MER is not a psychological disorder but a physiological issue caused by hormones, which is different from postpartum depression. The severity of D-MER symptoms can be evaluated by the assessment tool of the D-MER spectrum. Lactating women can relieve their symptoms through self-regulation, lifestyle changes, and professional guidance and treatments. Conclusions: The two cases studies about Chinese women with D-MER will enrich the knowledge of D-MER, and it might suggest some directions to health care workers for exploring scientific guidance and treatments for lactating women. Because the literature and published empirical studies about D-MER are scarce, further researches on the theory and interventions of D-MER are necessary.
