Lactation Mastitis - Causes

What are the causes of Lactation Mastitis?

The two main causes for lactation mastitis is

  • Milk stasis

Milk Stasis (Stagnation of Milk):

  • Milk stasis is the primary cause for development of lactation mastitis, which may or may not be accompanied with infection. 
  • Milk stasis results from stagnation of milk within the breast due to inefficient removal of milk. 
  • Infection may also occur in Milk stasis as the stagnant milk may provide a good nutrient supply for the growth of bacteria.
  • Lactation mastitis may occur when the breasts are filled with milk soon after delivery and milk is not removed by the infant from the breast, which may be due to:
  • Poor attachment of the infant to the breast
  • Ineffective suckling

  • Blockage in milk ducts
  • Increased milk supply
