Breastfeeding Lactation
More often than not, lactation is associated with pregnancy, breastfeeding, and the mother’s body preparing to care for the newborn baby. Though many times the mother’s body will produce milk on its own, sometimes the mother needs to receive additional help to produce enough milk for breastfeeding. Additionally, it is also possible to receive extended hormonal treatment for induced lactation. A small percentage of women can also begin lactating without any association to pregnancy—a condition known as galactorrhea where excessive milk is produced.
Natural Lactation
The mother’s body prepares to lactate in the final months of pregnancy, and it does so through three main hormones: estrogen, progesterone and placental lactogen. Especially at the time of delivery, the hormone prolactin levels increase to such an extent so as to initiate milk production, while at the same time the levels of estrogen and progesterone decrease. According to the CDC, the American Association of Pediatrics suggests that infants should be continuously breastfed during the first six months of their lives, while other foods are gradually introduced. It is also recommended that breastfeeding continues at intervals until about two years of age, but most infants are neither exclusively breastfed nor do they continue to breastfeed for as long as recommended.
Induced Lactation
Many mothers need to replicate the body’s process of milk production to either enhance the lactation process, or to recreate it because they are coming into motherhood without pregnancy. This is most common with mothers who wish to breastfeed their adopted baby. To achieve induced lactation hormone therapy is the first required step: supplemental estrogen or progesterone may be prescribed to mimic pregnancy, and it can last for months. A few months before the expected breastfeeding date, hormone therapy will cease and you will begin the process of pumping your breasts to encourage the release of prolactin. This is a lengthy process, and the pumping gradually increases in time and intensity. It is likely that in the case of induced lactation time may not be on your side, in which case other medications may be prescribed. However, what remains integral for the milk supply necessary for breastfeeding is the process of pumping.
Galactorrhea
A number of women begin lactating without any association to pregnancy, a condition known as galactorrhea. The most common symptom is one or both breasts producing excessive milk, while other symptoms may include random leaking from the nipples, enlargement of breast tissue, irregular periods, low sex drive, acne and headaches. In some cases the cause of this may be hard to find, but the general rule is that it happens due to hormone imbalances, or as a side effect of medications. Since the most common reason for milk production is increased levels of the hormone prolactin, galactorrhea may happen due to medications, underlying medical conditions, a tumor, or overstimulation of the nipples. As with any condition with various causes, how it can be treated depends on what is causing it and it is up to your healthcare provider to conduct the appropriate tests to pinpoint the cause.
