Breast Infections and Inflammations
The most common type of breast infection is lactational mastitis. This happens when a woman is breastfeeding. The nipples become cracked and sore, allowing bacteria from the baby's mouth to enter the ducts and rapidly multiply in the milk.
Breast Infections and Inflammations
What is lactational mastitis?
The most common type of breast infection is lactational mastitis. This happens when a person is breastfeeding. The nipples become cracked and sore. This allows bacteria from the baby's mouth to enter the ducts and rapidly multiply in the milk. Sometimes an infection also occurs because of a blocked milk duct. In both cases, the breast becomes hard, reddened, hot, and painful.
Treatment for lactational mastitis
Treatment will depend on your symptoms, age, and general health. It will also depend on how bad the condition is.
Your doctor may suggest trying to unblock the duct with warm compresses and massage. They may also prescribe antibiotics and an analgesic for pain. Your doctor will advise completely emptying the breast of milk regularly. Emptying the breast completely will also help prevent lactational mastitis. In some cases, lactational mastitis progresses and forms a pus-filled infection (abscess). This is a more serious condition that may need drainage.
