Will milk supply decrease when menstruation returns during breastfeeding?

During menstruation in the lactation period, milk supply may be somewhat affected and decrease, but the specific situation varies from person to person. This is mainly due to the rise in estrogen and progesterone levels during menstruation, which can suppress the secretion of prolactin, potentially leading to reduced milk production. However, this effect is usually insignificant for mothers who are otherwise able to breastfeed normally. Milk supply can also be influenced by various factors such as breastfeeding methods, nutritional intake, and emotional state. To increase milk supply, mothers can try relaxing, improving their nutrition, and increasing the frequency of breastfeeding. Although milk volume may slightly decrease during menstruation while breastfeeding, in most cases it does not affect the baby's growth and development.
