Mastitis, abscess and MRSA


Mastitis in a lactating woman is most often an inflammatory as result of an obstruction in the ductal system. The pressure of the accumulating milk creates swelling and added heat to the area. Symptoms include a hard, sore area in the breast, probably a red colouring of the skin and less milk flow, leading to more pressure. I a healthy mother the cause for mastitis is mostly not a bacterial infection (but the inflammated tissues can easily get infected). In women with other infections and women who are hospitalized a primary infectious mastitis is more presumable. The causing germs can be mom’s own skin flora, but there seems to be an increase in MRSA as infecting agent. When prescribing antibiotics for infectious mastitis the physician will want to make sure to test which pathogen is causing the infection in ord4r to be able to start treatment with the right medication. During the course of treatment it is not advisable to stop breastfeeding.
