Whether breast augmentation will affect breastfeeding depends on two conditions. In principle, there should be no effect, but if there are some complications in the process of breast augmentation, there may be some effect. At present, breast augmentation surgery generally includes two methods, the first method is the more traditional silicone implant surgery, this surgery is actually placed in the gap behind the breast tissue or placed under the pectoralis major muscle, this case is generally the implant is not in direct contact with the breast tissue, so it should not affect the later breastfeeding. The second surgical method is autologous fat transplantation, which is the transplantation of fat from other parts of the body to the breast, a filling method that does not hurt the breast tissue and therefore does not affect breastfeeding. However, if there are some accidents during the surgery, which damage the breast tissue, or if there is septic infection or fat liquefaction after the surgery, it is possible to accumulate the breast tissue, which will affect the breastfeeding later. If you have had breast augmentation surgery, you should pay attention to breast care, you can often do breast massage, and you should also pay attention to frequent review and evaluation to try to avoid some adverse complications. During the breastfeeding period, you should pay attention to the prevention of mastitis and other conditions.
