Why is my milk supply so low on my period?

Understanding Low Milk Supply During Menstruation
For breastfeeding mothers, the return of menstruation can bring about a range of changes, including a noticeable dip in milk supply. This phenomenon is not uncommon and can be attributed to several physiological factors linked to hormonal fluctuations that occur during the menstrual cycle.
Hormonal Shifts and Their Impact
As a woman approaches her period, her body undergoes significant hormonal changes. The levels of estrogen and progesterone fluctuate, which can directly affect milk production. Research indicates that many women experience a decrease in milk supply just before their period begins, with this drop often persisting throughout the duration of menstruation. The hormonal shifts can lead to a slower milk flow, making it more challenging for breastfeeding mothers to maintain their usual supply.
Calcium and Magnesium Levels
Another contributing factor to reduced milk supply during menstruation is the potential drop in calcium levels. Some lactation consultants suggest that the menstrual cycle can lead to decreased calcium levels in the body, which may impact milk production. To counteract this, some experts recommend that women consider taking calcium and magnesium supplements starting from ovulation through the first day of their cycle to help stabilize their milk supply.
Individual Variability
It’s important to note that the extent of milk supply fluctuations can vary significantly from one woman to another. While some may notice a marked decrease, others might not experience any change at all. Factors such as breastfeeding frequency, overall health, hydration, and nutrition can all play a role in how a woman’s body responds to the hormonal changes associated with menstruation.
Strategies to Manage Supply Drops
For mothers concerned about maintaining their milk supply during their period, there are several strategies that can help. Increasing breastfeeding frequency or pumping can stimulate milk production, as demand often drives supply. Staying well-hydrated and ensuring a balanced diet rich in essential nutrients can also support overall milk production.
In summary, while a drop in milk supply during menstruation is a common experience for many breastfeeding mothers, understanding the underlying hormonal changes and taking proactive steps can help manage this temporary fluctuation.
