When women are pregnant and breastfeeding, breast tissue gradually expands and breasts become fuller than usual, after they stop breastfeeding, breast glands start to shrink and skin and ligaments start to relax, which leads to sagging and dry breasts, for such breasts, choosing autologous fat transfer for breast augmentation can achieve a very good result. Because at this time, the breast space is enough, because the breast skin and tissues get relaxed in the process of breastfeeding, so the breast has a good space to fill with fat, at the same time, in the process of breastfeeding, the breast is like the land that has been loosened, its tissue gap pressure becomes smaller, and the transplanted fat is easier to establish blood transport, thus improving the survival rate, so that the breast after breastfeeding, through autologous fat transfer breast augmentation, can get a very good improvement. If the postpartum breast sagging is serious, it can be treated with breast sagging correction. Breast sagging correction is a better way to treat sagging breasts. The surgical incision is usually made at the patient’s areola, where the skin is cut and the subcutaneous tissue and the surface of the breast gland are filled into the breast, and then the nipple and areola are displaced upward to correct the sagging breast. The procedure has a quicker recovery and is also generally not associated with any adverse effects.
