Deflated breasts after breastfeeding is usually a normal physiological phenomenon. It can be improved by breast augmentation surgery, such as autologous fat transplantation or silicone gel breast augmentation surgery. 1. Autologous fat transplantation: Autologous fat transplantation is actually the transplantation of fat from different parts of the body to the breasts to fill the volume and improve the appearance. 2. Silicone gel breast augmentation surgery: Silicone gel breast augmentation surgery involves making an incision around the patient’s breasts, then implanting suitable breast silicone implants, and finally sewing up the incision to achieve visible breast augmentation results. It is recommended that women who need breast augmentation surgery should go to regular hospitals to avoid other serious consequences.
