What to Know About Periods While Breastfeeding

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Breastfeeding is a crucial period for both mother and child, offering numerous health benefits. However, it also brings about significant changes in a woman’s body, including alterations in the menstrual cycle. Understanding these changes can help new mothers manage their expectations and health during this time.

Menstrual Cycle Changes During Breastfeeding

Breastfeeding can significantly impact the menstrual cycle. Lactating women often experience a delay in the return of their periods, a phenomenon known as lactational amenorrhea. This delay is primarily due to the hormonal changes associated with breastfeeding, particularly the elevated levels of prolactin, which suppress ovulation.

Chemosignals and Menstrual Cycle Modulation

Interestingly, compounds from lactating women and their infants can influence the menstrual cycles of other women. A study found that exposure to breastfeeding compounds can modulate ovarian cycle length, disrupting the normal regulation and increasing the variance of cycle length. This effect is driven by changes in both the follicular and luteal phases of the cycle, altering the timing of the pre-ovulatory surge of LH1.

Factors Influencing Menstrual Cycle Resumption

Several factors can influence when a breastfeeding mother’s menstrual cycle resumes. These include the frequency and exclusivity of breastfeeding, the mother’s overall health, and individual hormonal responses. For instance, mothers who breastfeed more frequently and exclusively are likely to experience a longer delay in the return of their periods.

Breastfeeding and Postpartum Hemorrhage

Postpartum hemorrhage (PPH) can also affect breastfeeding and, consequently, the menstrual cycle. Women who experience PPH may face challenges in initiating and sustaining breastfeeding, which can, in turn, influence the timing of the return of their menstrual cycles. Factors such as maternal-infant separation, ICU admission, and the use of certain medications during PPH are associated with lower rates of breastfeeding, potentially affecting menstrual cycle resumption3.

Barriers to Successful Breastfeeding

Early postpartum barriers to breastfeeding can also impact the menstrual cycle. Common barriers include perceived inadequate milk supply, latch problems, and medical issues. Support from International Board Certified Lactation Consultants (IBCLCs) has been shown to help mothers overcome these barriers, thereby promoting successful breastfeeding and potentially influencing the timing of menstrual cycle resumption4.

Conclusion

Understanding the interplay between breastfeeding and the menstrual cycle is essential for new mothers. Breastfeeding can delay the return of periods due to hormonal changes, and various factors, including breastfeeding frequency and postpartum complications, can influence this delay. Support from healthcare professionals, particularly IBCLCs, can help mothers navigate breastfeeding challenges, ultimately impacting their menstrual health.
