Milchfluss

Milchfluss, in the context of lactation, refers to the milk ejection process or let-down, the moment when milk is released from the mammary glands and flows toward the nipple for feeding. It occurs alongside ongoing milk production and is a key part of successful breastfeeding.

Mechanism: Milk production is driven by prolactin from the pituitary gland, which maintains the alveolar cells that synthesize milk. Milk ejection is triggered by oxytocin, released from the posterior pituitary in response to nipple stimulation such as infant suckling, crying, or even conditioned cues. Oxytocin causes the myoepithelial cells around the milk-producing glands to contract, pushing milk through the ducts to the nipple. Many people experience a distinct let-down sensation—sometimes a tingling, warmth, or fullness—though some may not notice it clearly.

Factors influencing milk flow: Regular and effective infant suckling or milk expression supports continuous milk flow. Let-down can be influenced by stress, fatigue, hydration, and latch quality. Some individuals feel the let-down strongly, while others notice only the result of milk flow or a decrease in tension rather than the sensation itself.

Management and considerations: Ensuring a good latch, frequent breastfeeding or pumping, and skin-to-skin contact can help maintain milk flow. If milk is not draining well, or if there are signs of engorgement, plugged ducts, or mastitis, consulting a lactation consultant or healthcare professional is advisable. Medications or medical conditions that affect oxytocin or prolactin should be discussed with a clinician.
