Bröstmjölksutdrivning

Bröstmjölksutdrivning, also known as the milk ejection reflex or let-down reflex, is a physiological process that enables a lactating mother to release her breast milk. This reflex is triggered by a complex hormonal interplay, primarily involving oxytocin and prolactin. When a baby latches onto the nipple and begins to suckle, sensory nerves in the nipple send signals to the mother's brain. In response, the pituitary gland releases oxytocin. Oxytocin travels through the bloodstream to the mammary glands, causing the tiny muscles surrounding the milk-producing alveoli to contract. This contraction squeezes the milk out of the alveoli and into the milk ducts, making it available for the baby to consume.

Prolactin, another hormone released by the pituitary gland, plays a crucial role in milk production. While oxytocin facilitates the release of existing milk, prolactin stimulates the mammary glands to produce more milk. The frequency and duration of suckling directly influence the release of both oxytocin and prolactin, creating a feedback loop that ensures a continuous supply of milk tailored to the baby's needs.

The bröstmjölksutdrivning can also be triggered by stimuli other than direct suckling, such as the sound of a baby crying, the thought of the baby, or even a warm shower. Conversely, stress, pain, or distractions can sometimes inhibit the reflex, making it more challenging for the mother to breastfeed effectively. Understanding and supporting this reflex is a key aspect of successful breastfeeding.
