O91: Infections of breast associated with childbirth

Infections of the breast associated with childbirth, also known as puerperal mastitis, mainly occur during the postpartum period, especially when the mother is breastfeeding. These infections are typically caused by bacteria that enter through cracked or sore nipples during breastfeeding. Common symptoms include breast pain, swelling, warmth and redness, and systemic symptoms such as fever and chills. These infections can potentially escalate, resulting in an abscess if not properly managed, which is a collection of pus within the breast tissue. In severe cases, the infection can spread into the bloodstream, causing a more dangerous condition known as sepsis. This group of conditions primarily affect the female reproductive system and the immune system, mainly the body's response to bacterial invasion. The progression of these conditions heavily depends on the time and effectiveness of treatment initiated.
