The term dysphoric milk ejection reflex (D-MER) came from Alia Macrina Heise who described it in 2007. [8] It was chosen due to the emotional reaction (dysphoria) to milk let-down (milk ejection reflex). The "milk ejection reflex" is abbreviated among lactation professionals and referred to as the M-E-R.
Milk ejection is initiated in the mother's breast by the act of suckling by the baby. The milk ejection reflex (also called let-down reflex) is not always consistent, especially at first. Once a woman is conditioned to nursing, let-down can be triggered by a variety of stimuli, including the sound of any baby.
[10]: 18–21 [25] This process is known as the milk ejection reflex, or let-down. [10]: 18–21 Because of oxytocin's dual activity at the breast and the uterus, breastfeeding mothers may also experience uterine cramping at the time of breastfeeding, for the first several days to weeks. [25]
Milk ejection reflex/Letdown reflex: in lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be 'let down' into lactiferous ducts, from where it can be excreted via the nipple. [73] Suckling by the infant at the nipple is relayed by spinal nerves to the hypothalamus.
Overactive let-down (OALD) is the forceful ejection of milk from the breast during breastfeeding. In some women it occurs only with the first let-down in a feeding, occasionally women may have multiple strong letdowns during a feeding. OALD can make breastfeeding difficult and can be the source of some breastfeeding complications. It may also ...
The suckling stimulus also triggers the release of oxytocin from the posterior pituitary gland, which triggers milk let-down: Prolactin controls milk production (lactogenesis) but not the milk-ejection reflex; the rise in prolactin fills the breast with milk in preparation for the next feed. The posterior pituitary produces a yet-unidentified ...
Breastfeeding difficulties refers to problems that arise from breastfeeding, the feeding of an infant or young child with milk from a woman's breasts.Although babies have a sucking reflex that enables them to suck and swallow milk, and human breast milk is usually the best source of nourishment for human infants, [1] there are circumstances under which breastfeeding can be problematic, or even ...
Oxytocin is responsible for the milk let-down reflex as a response to neonate suckling. It is released from the posterior pituitary gland in a pulsatile manner, via stimulation of the vagus nerve.
