It's hard to give definite medical advice over the internet, so you should start with a consultation with a board certified plastic surgeon. Your options for rejuvenating your breasts after child birth and breast feeding usually involve breast implants, a breast lift or both. There are different techniques that can be employed to improve upon the shape and appearance of the breasts. These may include tightening of the skin and repositioning of the breast tissue, insertion of breast implants, or a combination of both techniques. In terms of breast implants, there are a variety of augmentation techniques that can use saline or silicone implants. The procedure is usually done as an outpatient procedure to help augment a woman's breasts or replace volume that has been lost after childbirth, breast feeding, through normal aging or weight loss. This may sometimes require more than one operation if both a lift and implants are needed. Which technique is used is based mostly on the individual patient. In general, if the nipple "hangs" more than an inch below the breast fold, some type of lift will be needed.
