Can mastitis be prevented?

A comfortable latch, feeding in response to your baby's cues and avoiding unnecessary extra pumping can help milk production stay closer to what your baby needs.

Mastitis is inflammation in breast tissue. During breastfeeding, it may begin when milk is not moving comfortably or supply exceeds removal, causing swelling that narrows the milk ducts. Infection can occur, but redness and pain do not automatically mean bacteria are present.

Poor attachment, skipped feeds, abrupt weaning, oversupply and pressure from a tight bra or strap can contribute. Mastitis can also occur outside breastfeeding, so a new hot, painful or swollen breast still deserves medical assessment.

Let your baby feed when they show hunger cues and check that swallowing is effective and feeding is comfortable. Seek skilled feeding support for persistent nipple pain, a shallow latch, recurrent blocked areas or difficulty managing oversupply.

Avoid deep breast massage, forceful squeezing and pumping to completely empty the breasts, as these can worsen swelling or drive excess production. Wear a supportive bra that does not press into breast tissue. If weaning, reduce feeds gradually when possible rather than stopping suddenly.

At the first sign of a tender swollen area, continue normal feeding if you can, use a cool compress for comfort and rest. Express only enough for comfort or to feed your baby when direct feeding is too painful.

Contact a clinician if a hot, painful or swollen area is worsening, you develop fever or flu-like symptoms, or home measures are not starting to help within a day. Assessment is also needed if mastitis occurs when you are not breastfeeding or keeps returning.

Get urgent help for confusion, faintness, severe weakness, breathing difficulty, repeated vomiting, very little urine or rapidly spreading redness. A distinct, increasingly painful swelling may be an abscess and needs prompt examination.

Ask whether your symptoms suggest inflammation alone, bacterial infection or an abscess; whether antibiotics are needed; and how to keep feeding or expressing safely. For repeat episodes, request an assessment of latch, pumping pattern, oversupply and any persistent breast lump.
