What are the causes of Lactation Mastitis?

The two main causes for lactation mastitis is

  • Milk stasis

  • 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:

  • Increased milk supply
