The change in breast odor while breastfeeding can be attributed to a few factors, primarily related to hormonal shifts and your baby's interaction with your skin.
Possible Causes of Breast Odor During Breastfeeding:
-
Pheromones: Breastfeeding mothers may excrete different pheromones. One theory suggests these pheromones act as a form of communication with the newborn, aiding in feeding and bonding. This is a natural biological process.
-
Infant Saliva: Your infant's saliva can contribute to a change in your body odor. When your baby nurses, their saliva mixes with breast milk and skin on your areola and nipple. This mixture, especially when exposed to air, can sometimes develop a distinct smell.
Other Potential Contributing Factors:
- Sweat: Breastfeeding can cause hormonal changes that lead to increased sweating, especially around the breasts. Sweat provides a breeding ground for bacteria, which can cause odor.
- Milk Leakage: Leaked breast milk, if not properly cleaned, can become sour and create an unpleasant smell.
- Mastitis: Although less common, a breast infection like mastitis can sometimes cause a foul odor. Other symptoms of mastitis include breast pain, redness, swelling, and fever.
What You Can Do:
- Good Hygiene: Wash your breasts regularly with mild soap and water, especially after feeding. Avoid using heavily scented soaps or lotions, as they can irritate your baby.
- Change Breast Pads Frequently: If you use breast pads, change them frequently to prevent milk leakage from causing odor.
- Air Dry: Allow your breasts to air dry after washing them or after nursing.
- Check for Mastitis: If you suspect a breast infection, contact your doctor immediately.
- Stay Hydrated: Drinking plenty of water can help reduce body odor.
In most cases, breast odor during breastfeeding is normal and related to hormonal changes or your baby's saliva. However, if the odor is accompanied by other symptoms like pain, redness, or fever, it's important to consult a doctor.
