Mastitis

Risk factors

Risk factors for mastitis include:

  • Previous bout of mastitis while breast-feeding
  • Sore or cracked nipples — although mastitis can develop without broken skin
  • Wearing a tightfitting bra or putting pressure on your breast when using a seat belt or carrying a heavy bag, which may restrict milk flow
  • Improper nursing technique
  • Becoming overly tired or stressed
  • Poor nutrition
  • Smoking
