Breasts often sag, that is, the ligaments that support your breasts get loose over time due to several factors including weight gain and loss, breastfeeding, and aging. “Is it possible to lift up breasts?” Many women, especially who gave birth and who lose weight frequently wonder if it is possible to lift their breasts, so it is one of the most frequently asked questions on aesthetic issues. Breast sagging can be corrected by a breast lift surgery, also known as “mastopexy”. These procedures are performed by plastic surgeons.
