Mastitis is one of the main causes of avoidable cessation of breastfeeding which increases morbidity in childhood, however, there is no uniformity in diagnostic and therapeutic criteria. The diagnosis of acute mastitis is mainly clinical. Only in certain cases, a milk culture is indicated. Regarding treatment of mastitis, it is fundamental to empty the breast, so breastfeeding should continue. It is recommended to start antibiotic therapy if symptoms persist or if there is considerable clinical impact. There is insufficient evidence of the importance of other types of mastitis (subclinical and subacute). There is also a lack of evidence that these types of mastitis are responsible for breast pain or for low infant weight gain. Furthermore, there is not enough evidence regarding the effectiveness of probiotics in the treatment and prevention of mastitis.
