What happens to a woman's breasts during pregnancy?

During pregnancy, breasts will develop and enlarge in preparation for breastfeeding. These changes occur as a result of hormone surges, and the extent by which the breast volume increases varies between women. By about 6 months after a woman has stopped breastfeeding (or, if not breastfeeding, after childbirth) the breasts will most likely return to their pre-pregnancy appearance. Some women are, however, left with a significant loss of shape and/or volume, and sagging (breast ptosis). These effects can be addressed by a Breast Lift procedure, or in combination with a Breast Augmentation.
