Mastitis is inflammation or swelling of your breast tissue, particularly the milk ducts and glands in a breastfeeding woman.
There are 2 types of mastitis: non-infectious mastitis and infectious mastitis. Non-infectious mastitisThis type of mastitis is usually caused by breast milk staying within the breast tissue. This happens because of a blocked milk duct or a breastfeeding problem. If left untreated, the milk left in the breast tissue can become infected, leading to infectious mastitis. Infectious mastitisThis type of mastitis is caused by bacterial infection. It is important to receive treatment immediately to prevent complications, such as an abscess in the breast. You can get infectious mastitis even when not breastfeeding. What are the causes of mastitis?Milk stasisWhen milk isn't completely emptied from a breast at feedings, the milk left in the breast tissue can back up and become infected. This is known as milk stasis. Milk stasis may be caused by:
Bacteria entering your breastBacteria from your skin's surface and baby's mouth can enter the milk ducts through a break or crack in the skin of your nipple or through a milk duct opening. Bacteria can multiply, leading to infection. These germs aren't harmful to your baby – everyone has them. They just don't belong in your breast tissues. Nipple damage may be caused by a baby not being latched on correctly or having a tongue tie. In rare cases, untreated dermatitis of your nipple or surrounding area can be the cause. What are the risk factors for mastitis?You are more likely to get mastitis if you:
What are the symptoms of mastitis?While mastitis is common in the first month of breastfeeding, it can also occur at any stage when you are lactating and particularly when the number of breastfeeds or milk expressions is suddenly reduced. Symptoms of mastitis include:
Most cases of mastitis are caused because your baby is not latched on or positioned on your breast correctly. This leads to milk stasis, with blocked milk ducts and alveoli, and nipple trauma. What is the treatment for mastitis?The following are the key ways of managing mastitis:
See your doctor or midwife straight away if you have a fever, as you may need antibiotics to treat the infection.
If you don't improve within 24 hours of treatment, seek further medical advice. If you have had all the appropriate treatment for mastitis and an area of your breast remains hard, reddened and painful, a breast abscess may have formed or be forming. If this happens, see your doctor for treatment. Read more about breast abscess. What can I do to manage mastitis?Empty your breast
Gentle massage and compresses
Rest and pain relief
Expressing blockagesIf you are unable to latch your baby properly, or express your milk normally, you may opt to express the blockage yourself. Sometimes, during gentle massage, you can even accidentally express it! The coagulated milk responsible for the blockage may look like a rock, grain of sand or even a strand of spaghetti. If your baby clears this blockage during breastfeeding, this is not harmful. Breast lumpsDuring pregnancy, your breasts may feel lumpy. This is usually because the glands that produce milk are increasing in number and getting larger in preparation for breastfeeding. However, because 1 in 9 New Zealand women develop breast cancer in their lifetime, see your doctor if you notice any changes in your breasts. Read more about breast lumps and changes.
