A breast lift is most commonly done to correct changes that have occurred in the breast shape. A breast lift is a common procedure chosen to give a perkier, more youthful position to the breasts. After 30 years of age, a woman’s breasts usually begin to change. Causes of breast sagging include hormonal influences, heredity traits, pregnancy, and weight loss. Breast lift surgery can reshape the breasts and change them from a flat, droopy shape to a higher, rounder, more aesthetically pleasing youthful shape. The results of breast lift surgery can last for decades as long as the patient maintains her weight and uses proper supportive bras.
