Mastitis - Fact Sheets

Mastitis is inflammation of the breast, which may lead to infection.

Causes

• Rapid weaning

• Inadequate drainage of breastmilk

• Poor attachment to the breast

• Nipple trauma

• Missed feeds

• A tight constricting bra leading to overfilling of breasts, poor drainage and blocked ducts.

Signs and symptoms

• A reddened area on the breast, which may be tender and hot to touch

• Flu like symptoms may be experienced, including aching joints, fever (38.5C or above) and chills.

Prevention

Early management of mastitis

• Application of warmth (e.g. heat pack) to the affected area of the breast

• Gently massage any breast lumps

• Breastfeed or express the breast until the area is softened and feels more comfortable

• You may need to repeat this process a number of times before the blockage resolves

• If the symptoms do not improve it is important to seek medical advice.

Subsequent management of mastitis

• Continue to breastfeed and/or express

• Prior to feeding or expressing apply warmth (heat pack) to the affected area to improve milk flow

• Following massage/ breastfeeding / expressing, apply a cool pack for a few minutes to reduce discomfort

• Pain relief tablets may be necessary eg Paracetamol or Ibuprofen

• Maintain a good fluid intake (up to 8 glasses of water per day)

• It is important to rest as much as possible

• If antibiotics are prescribed, take as directed. Your doctor will ensure any antibiotic prescribed is safe for your baby.
