Would I need to get another breast lift after pregnancy?

It really depends on your body and how it responds to pregnancy. But if you already have sagging, there is a good chance that you will need additional surgery after you are done with the breast feeding if you decide and ofcourse after you are done with your pregnancies.

It is hard to predict because everyone reacts differently to pregnancy.

Hello!  Thank you for your question.  This is an excellent question, and one very common for those seeking rejuvenation of the appearance of her breasts, especially after pregnancy. Your complaints are likely due to post-pregnancy changes of your breasts as they likely enlarged and stretched during and immediately after your pregnancy as they became engorged with milk for lactation. Now, they have a typical "deflated" appearance as they have settled but have lost much of the enlargement during your pregnancy. Options to ameliorate your complaints would include implant placement, breast lift, fat grafting, or a combination of these modalities. A consultation with a plastic surgeon may help you decide which procedure(s) may be the best option for you. It may be wise to wait until after you have completed child bearing, as similar changes will occur after each pregnancy. Also, it is not uncommon to have different sizes of breasts, but I would recommend evaluation if there is a sudden change in one side from another, a mass is felt to account for the size difference, any changes in skin or nipple appearance, or drainage/bleeding from the nipple.  Changes can certainly continue after future pregnancies.  Hope that these answers help!

         It’s not unusual for
women to undergo breast augmentation and breast lift prior to pregnancy. Many
women don’t have plans to become pregnant in the near future. Under these
circumstances it’s reasonable to proceed with surgery when women are unhappy
with their breast aesthetics. In contrast, patients who anticipate becoming
pregnant in the near future should delay surgery until they are done having
children.

 

         In some cases,
breast lift surgery can adversely impact the ability to breast feed. In
patients who place high value on breast feeding, breast lift should be delayed
until child bearing is complete.

 

         Conversely,
pregnancy can have an adverse impact on breast aesthetics. In patients who have
developed breast sag prior to pregnancy, breast sag following pregnancy can
recur. Under these circumstances, surgical revision is highly probable.

 

         It’s important that
all of these issues be considered before proceeding with breast lift surgery in
women who may not be done having children. If you’re considering breast lift in
combination with breast augmentation prior to pregnancy, consultation with a
board certified plastic surgeon is appropriate. 

The need for cosmetic breast surgery after pregnancy depends on how your breasts settle afterward. If you don't experience a significant amount of droopiness afterward, you may not need anything at all. However, be aware that if you get incisions around the areola your ability to breastfeed may be altered and formula supplementation may be necessary. Good luck!

I see two related issues here. The first is the cosmetic issue regarding how the breasts might look after the pregnancy. The second issue is whether or not breast feeding is an issue for you.
A mastopexy augmentation may alter or eliminate your ability to breast feed which you need to consider before having surgery.
If you have the surgery first, the breast will go through all the normal physiologic changes which accompany the pregnancy. this may lead to the breast enlargement during the pregnancy and subsequent falling of the expanded breast skin off the implant. Depending on the degree of change, you may need to have a subsequent procedure.
Good luck
