Different causes of Mastitis

You may suffer from mastitis if you have either a blocked milk duct or a bacterial infection.

1} Blocked milk duct

You may have a blocked milk duct if one breast or both the breasts don’t empty completely during feedings. This may lead to clogging of one of the milk ducts which can cause milk to back up in them and give rise to breast infection. In fact, a major reason for mastitis in first time mothers is wrong breast-feeding technique. Breast feeding is a skill and poor technique may lead to trapping of milk in the breast.

2} Bacterial infection

You may also suffer from this condition if there is a bacterial infection in your breast tissue. This may happen in new mothers since they are new to breastfeeding. Bacterial infection from the skin of the mother’s breast can pass on to the baby thorough its mouth and in turn can enter the milk ducts of the mother if there is a break or crack in the nipple skin. The bacteria may even enter through openings of the milk duct on the nipple. Once the bacteria have entered your breast they find a good habitat in the stagnant milk of your breast. This is possible since milk is not emptied fully as you are just learning the techniques of breast feeding. This provides a breeding ground for the bacteria. The saving grace is that the antibacterial property of mother’s milk helps in protecting babies from such bacteria.
