What is a common risk factor for mastitis in nursing mothers?

A plugged milk duct is indeed a common risk factor for mastitis in nursing mothers. When milk is not effectively removed from the breast due to blockage in the ducts, it can lead to an accumulation of milk. This stagnation creates an environment conducive for bacterial growth, which can cause inflammation and infection, ultimately resulting in mastitis.

Breastfeeding regularly or frequently is generally protective against mastitis because it helps ensure that milk is effectively emptied from the breasts, reducing the likelihood of clogged ducts. Similarly, physical exercise, while beneficial for overall health, does not directly contribute to the likelihood of developing mastitis. Understanding the importance of frequent and effective breastfeeding can help nursing mothers minimize their risk of mastitis by keeping the milk flowing and preventing any blockages.
