It largely depends on the skill and technique of your chosen plastic surgeon. Most women can still breastfeed normally, as long as their nerves, milk ducts, and breast tissues aren’t damaged. On the other hand, some women might produce less breastmilk.
You wouldn’t really know until you start nursing.
Breast reduction surgery may affect the ability to breastfeed.
The reason for that is the procedure is designed to remove skin and breast tissue. In that breast tissue are glands which produce and allow for milk storage. So by removing these glands, (ONE) we may decrease the capacity to house and store the milk, and (TWO) we may affect the way that’s transported to the nipple, and ultimately to the baby.
So it doesn’t always affect breastfeeding, however it may primarily affect breastfeeding in the sense that you one is not able to produce enough milk or the baby is not able to retrieve enough milk to satisfy.
The second thing related to breastfeeding and breast reduction surgery is that after the procedure you may choose to have another child or your first child or whatever the case may be but any subsequent children may again increase the size of the breast related to the engorgement from pregnancy and ultimately the physiologic effects that are involved in breastfeeding.
That breast engorgement may create a situation again MAY create a situation, such that in the future you may require an additional breast procedure.
So those are two things to think about. In my experience it hasn’t been a problem and actually the relief that most women get from their large breasts outweigh the possibilities of breastfeeding in the first place. However there are, there is a group of women who do present AFTER having children and AFTER breastfeeding and certainly breastfeeding has done a number on their breasts increasing the size of the breasts and increasing the symptoms associated with having those large breasts.
