Is significant weight gain after breast augmentation normal?

Your implants only weigh around 2 pounds combined.  The remaining weight is most probably water and stool.  I have found that taking stool softeners, once constipated, do not allow for proper clearance.  You may want to use something stronger like Citrate of Magnesia (over the counter).  The water weight generally resolves over a two week period and may be aided by lowering your normal salt intake.  Good luck in your recovery.Dr Taranow, NYC Plastic Surgery

Thank you very much for your
interesting question. Weight gain after
breast augmentation will occur due to a combination of the implant itself and
any fluid retention and reduction of exercise levels associated with having an
operation. To work out the typical increase
in weight following breast augmentation you should add the volume of the weight
of your implants together. If the implants are measured in cc's the weight is very similar to the amount of cc’s. In addition you should expect
some fluid retention following your operation and also a moderate amount of
weight gain which would be caused by your reduction in exercise levels.The good news is that the
swelling should reduce with time which can take up to 3 months to go down and
the weight gain should reverse when you get back to your exercise regime.I hope this has been helpful.
