Can I increase the size of my existing saline breast implants?

Usually, breast implants have a range of what they can be filled to. Depending on the type of implant used and company, that can range. But in general you will not get a significant enlargement just by filling up your implants. Most patients will need to change out the implants to larger ones to achieve the desired affect. Hope that helps.

After having a baby, the breasts sometimes get smaller. If you have saline implants, it is not recommended to go back in and fill the implants some more. Implants are made to have a certain fill. If they are overfilled too much, then they will feel hard. If you need larger amounts of fluid, then you are best to get a new implant with the correct size and volume.

While I agree with what the other plastic surgeons have said here, there are some important issues to discuss.

Breast volume post-partum can change significantly.  In addition, the skin on your breasts may undergo significant change.  It is important to give your breasts a chance to recover after your pregnancy and breast feeding. 

Typically, patients should wait 6 months to one year to see the final shape of your breasts.  Patience will significantly improve the chance of you being able to accurately assess what (if any) changes need to happen.

Congratulations on the new addition to your family. 
 
I hope this helps.

Hello,

If you are looking for much of a change in size, new saline implants are usually required. Fill tolerance for your current saline implants can't be much more than 25-75cc which doesn't amount to much of a change in cup size. Re-filling the implants can also void their warranty.

Unfortunately there is no other option but to replace your current implants with larger implants. Adding saline to current implants is not recommeneded.
