Breast engorgement is a buildup of milk in the breasts that can cause pain, firmness, redness, and swelling.
It most often occurs in the first few days after birth. Breast engorgement may happen if the baby has difficulty latching or feeding effectively, or if milk supply increases rapidly.
Management of breast engorgement should be guided by a lactation consultant, midwife, or OB-GYN. It usually involves massage and cold or warm compresses to ease symptoms and improve milk flow, which helps release the milk.
Common symptoms
The main symptoms of breast engorgement are:
-
Breasts that are very full of milk and feel very hard
-
Increased breast size
-
Red, shiny areas on the breasts
-
Flattened nipples, which can interfere with milk flow
-
Discomfort or pain in the breasts
-
Fever (in some cases)
When the nipples become flattened, it can be harder for the baby to latch. This can make it more difficult for the baby to remove milk, which may increase breast fullness, pain, and discomfort.
Breast engorgement is common in the early days of breastfeeding because milk production increases during this time. It can appear 2 to 4 days after delivery and usually lasts about 24 to 48 hours.
Confirming a diagnosis
The diagnosis of breast engorgement is clinical and is made by a healthcare provider based on symptoms and a physical examination of the breasts. Additional testing is usually not needed.
During the breast exam, the provider can rule out other conditions with similar symptoms, such as a plugged duct or mastitis.
According to the American College of Obstetricians and Gynecologists (ACOG), a focused history and physical examination are essential for distinguishing breast engorgement from other causes of breastfeeding pain and related breast symptoms.
The provider should also ask about how breastfeeding is going, including the baby’s latch and how often the baby is feeding.
Possible causes
Some common causes of breast engorgement include:
-
Delay in starting breastfeeding after birth
-
Producing more milk than the baby removes
-
Difficulty with breastfeeding technique or latch
-
The baby not sucking effectively
-
Feeding the baby infrequently or on a strict schedule
-
Using supplements or methods intended to increase milk supply
When there is too much milk, it can build up inside the milk ducts. This changes the milk’s natural flow, making it thicker and even harder to move through the ducts and out of the breast.
Management strategies
Breast engorgement should be managed by a healthcare provider, such as a lactation consultant, midwife, or OB-GYN. Recommended strategies may include:
-
Breastfeeding often on demand, whenever the baby wants, or at least every 3 hours
-
Not delaying the start of breastfeeding and not skipping feedings
-
Expressing excess milk by hand or with an appropriate breast pump until it becomes easier for the baby to latch
-
Checking whether the baby’s latch is correct
-
Emptying the breast completely at each feeding
-
Applying cold compresses right after the baby finishes feeding to reduce breast inflammation
-
Applying warm compresses to the breast prior to a feeding to help release milk and improve its flow
It is also important to gently massage the breasts to help move milk through the milk ducts and make it flow more easily, which helps prevent breast engorgement.
In addition, a provider may recommend acetaminophen or ibuprofen to reduce breast pain and swelling.
Based on the American Academy of Pediatrics, parents should be supported with frequent breastfeeding and skilled lactation support, especially when latch or milk transfer is not going well
