Will a weight loss of 20 pounds lead to saggy breasts?

Thank you for sharing your excellent question.  Though nothing replaces an in-person examination, or full series of photographs, based on your age and current weight a 20lb weight loss is unlikely to lead to saggy breasts as your skin should retract well.  If you have breasts with extensive stretch marks or ones comprised largely of fatty tissue then you may experience some sagging.  Hope this helps.

This is very difficult to answer without photographs. Furthermore, you will only no the answer to that if you lose 20 pounds.

Christie.   In some people, significant weight loss can cause breasts to sag, but doubtful at your age with a 20 lb. weight loss. The real question is do you really need to lose that much weight? Height plays a factor. Talk to your family doctor about your desire to lose 20 lbs. Good luck!

Thank you for your question. A 20lb weight loss for you is substantial. At your age, your breasts are primarily glandular tissue, meaning that the size of your breasts are not as likely to change substantially with weight loss. As we age, the glandular breast tissue become more fatty and with weight gain and loss the size of the breast can fluctuate more substantially. Of course, any weight loss can leave you with loose skin. But, a woman's breasts are not fully developed until they have been pregnant and breast fed. Good luck with your weight loss goal! 

Breast sagging can depend on many factors such as age, genetics, overall body fat in relation to breast tissue, and prior pregnancy. Our guess would be that at your current age your breast is mostly dense tissue with relatively little fat, especially as your current weight is just 128, a low BMI or body fat content. To get to 108 you will need hard training and a high protein diet to push your weight down and stay "fit". Our bet is your breast will not sag, but do let us know.

The short answer is maybe.  The long answer is where you on your body you store and loose fat is genetically determined.  When some people loose weight it comes off their buttocks some their stomach and some their breast or other locations.   This may not be the same place you store fat when you gain weight.  Also it may change as you age.  A loss of 20 lbs for someone who weighs 128 pounds is quite significant  so I would say loose the weight before and give yourself several months for the skin to tighten.  

A 20 lb weight loss may lead to breasts sagging. It really depends upon many factors including, skin quality, fat content, glandular content, etc..

Losing 20 pounds may lead to loss of volume in the breasts which can lead to a certain amount of sagging of the breast. If you have not yet had children then there may be a lower likelihood of this happening in addition to the fact that you are quite young. Having said that, there is no way to be absolutely certain or predict how the breasts will look until you have first lost the weight. At this point, during the consultation the plastic surgeon can determine if an implant only, lift only, or a combination of an implant with a lift is what will be needed to meet your goals.

Thank you for your question. Especially in young like you and with slow weight loss it may not cause sagging. But can not predict for sure

Although I understand your concerns, I would suggest that you make   achieving your health goals a priority;  hopefully, at your young age a slow weight loss will not lead to too many changes in your breast size/position.   Obviously, good overall health will be of much better value to you long-term than maintaining a specific breast size/position. Best wishes as you work towards your goals.
