Is blocked milk due to too much milk or too little milk?

　　Blocked milk ducts are usually caused by an overabundance of breast milk. The detailed analysis is as follows:

　　A blocked milk duct refers to the condition where breast milk cannot flow normally through the mammary ducts, preventing smooth milk expression. This blockage typically occurs when there is an excessive milk supply. If the baby's sucking posture is incorrect during breastfeeding, it may cause uneven pressure on the mammary ducts, leading to duct obstruction. Failure to fully empty the breasts of milk can also result in clogged ducts. Excessive tension, anxiety, or emotional stress may interfere with normal breast function and contribute to milk duct blockages. Inflammation of the mammary ducts due to mastitis can also lead to blockages. When a milk duct is blocked, the breast may become swollen, painful, firm, and show localized swelling. Blocked ducts may cause redness on the skin surface of the breast along with a sensation of swelling. They can also lead to nipple pain and cracking, causing discomfort during breastfeeding. Increasing the frequency of breastfeeding helps promote milk flow and drainage, thereby alleviating symptoms of blocked ducts. Applying warm compresses before breastfeeding or when experiencing blockage can help dilate the mammary ducts and improve milk flow.

　　It is recommended to maintain adequate rest and healthy dietary habits to support normal milk production.
