How long can I have breast augmentation after delivery? This is generally a standard, because we consider that the breast volume will change obviously after breastfeeding, and the pregnant and breastfeeding breasts will increase obviously. After stopping breastfeeding, the breast will gradually shrink and its volume will gradually decrease. There will be sagging skin. Generally, the breast volume will reach a stable state after breastfeeding for half a year, so we generally advocate that the shape, relaxation and soft tissue state of the whole skin will reach a stable stage after stopping breastfeeding for half a year when doing autologous fat or prosthesis breast augmentation. At this time, how many prostheses we need to implant or how to adjust the shape of the breast is a more accurate cognition. This is a good time. Therefore, we advocate breast augmentation surgery after stopping breastfeeding for half a year. Another consideration is that there may be secretion of mammary ducts or glands after stopping breastfeeding, and there may be some activity. At this time, the mammary duct may be reactivated after proper stimulation, or a small number of glands may be secreted in the mammary tissue. At this time, breast augmentation or fat breast enhancement may be performed, and foreign bacteria or other microorganisms may retrograde, increasing the probability of infection. So from this point of view, it is also necessary to stop breastfeeding and the whole gland will reach a stable state. After half a year, the safety of fat breast enhancement and prosthetic breast enhancement will be higher.
