Some new mothers find that after weaning their babies from breast milk, their breasts are left sagging lower than they did pre-pregnancy. This is generally attributed to the actual breastfeeding, though a study by Dr. Brian Rinker of the University of Kentucky suggests that the act of breastfeeding has less to do with sagging breasts than pregnancy. Age and Body Mass Index (BMI), which can be affected by pregnancy-related weight gain, can also cause breasts to sag. With some work, and in some cases surgical procedures, your breasts can be restored nearly to their original, pre-baby appearance.
Exercise. Cardiovascular and other exercises that target the chest muscles are an effective way to prevent your breasts from sagging. Cardio, when paired with a healthy diet and lifestyle, can help keep your BMI down and help you maintain the shape and position of your breasts. Exercising your chest muscles through push-ups and other strength training exercises will help keep your chest muscles tight and strong, which can lift your breasts. Since breasts sag naturally with age, you should do these exercises early, even before you have children, to keep your chest in shape and your muscles taut. Consult your doctor before starting any exercise program.
Wear a supportive bra that fits properly. A well-fitting supportive bra is a helpful defense against sagging breasts. Arrange a proper bra fitting with a trained professional to ensure that your bra fits you properly. It should be comfortable with a strap that sits straight across the middle of your back without pinching. Wearing a bra that fully supports your breasts can take strain off of your chest muscles and help maintain your breast shape.
Wait for your body to adjust after breastfeeding. Pregnancy can cause changes to various parts of your body, including your breasts. When you begin breastfeeding your newborn, your breasts may become larger and fuller, but after weaning you may notice that they have begun to sag. They will return to roughly their original size and shape once you've completed the weaning process, according to lactation consultant Jan Barger.
Schedule a breast lift or implant consultation with a licensed plastic surgeon as a last resort if you are unhappy with the shape of your breasts and exercises and waiting do not yield the results you want. A simple breast lift can restore your breasts to your satisfaction, or you can opt for implants along with the breast lift to increase their size.
