Do Saline Breast Implants Cause Any Weight Gain or Retention over Time?

It wouldn’t
be unusual for patients to gain 23 pounds over the course of 18 years.This can occur for a variety of reasons, but
not because of breast implants. It’s important to note that two 450
cc saline implants would weigh about two pounds.Furthermore, breast implants wouldn’t cause a
generalized weight gain.For this
reason, your weight gain is probably not related to your breast implants, but
instead to normal factors that occur throughout an individual’s life.

Thank you for your question.  To answer your question most specifically, your breast implants have not caused any weight gain aside from the weight of your actual implant.  Furthermore, this weight gain from the weight of your implants would have been obvious immediately following your procedure.  I think that it is important to remember that as we age our metabolism changes and this can contribute to noticeable weight gains.  Hormonal changes in particular, especially in females, can affect the way that patients put on weight and where this additional weight gain (in the form of fat) is distributed.  If you are concerned with the size of your breasts and wish for them to be smaller, I would schedule a consultation with a board-certified plastic surgeon to discuss your options.  It is not uncommon for patients to undergo a breast augmentation as a young adult and then wish for a reduction or a smaller implant years down the line.  Some women gain weight in their chest as they age and unfortunately even with the most vigorous diet and exercise regimens, this weight does not always come off. In other women, they loose weight and volume first in the breasts than elsewhere.  I hope you find this helpful.

As a woman gets older, it is common for their breasts to get larger with the accumulation of fatty tissue. Since you mention that you also have gained weight, this may have increased your bust size naturally. However, breast implants do not cause weight gain or retention. 

Breast implants whether saline or silicone will not cause you to have water retention or gain weight (except for the weight of the implants).

There is no correlation between breast implants, both saline and silicone, with gaining or losing weight over time. One does see over time, however, the female breast tissue may increase in size normally and also have more drooping or ptosis, but that does not relate to the implant.
