Is It Possible for a Saline Breast Implant to Be Leaking Slowly?

Leaking of saline breast implants can deflate over a few hours or a few days, however once the leaking starts it won't stop.  That one of the greatest advantages of saline implants is that there isn't usually a question about whether its leaking or not.  You know because the breast the deflation is clearly visible and the saline just gets safely absorbed by the body.  It is unlikely that two weeks after surgery that both sides have partially deflated.  The change that you see is more likely and resolution of swelling after surgery and the dropping down of the implants into a more natural position. 

Yes, implants can leak slowly.  I have seen instances where it has taken several months to discern a certain leak in a saline implant.  Because your surgery was so recent, it is too soon to be sure.  However, a leak this soon after surgery is unlikely and it is more likely that you are seeing your pre-op breast asymmetry magnified.  10cc difference in implant fill is not visibly noticible. Your breast asymmetry is not only in volume, but inra-mammary fold height too. This may look more obvious after surgery, as in your case.
