Will Gaining Weight Affect Results of Breast Lift?

Hi there-
The extent to which any gain in weight will affect your breast lift will depend on how much weight you gain, how fast, how long after your breast lift it occurs, your skin type, how old you are, your lifestyle, the type of breast lift you have done, the types of bras you like to wear.....
In other words, your question is impossible to answer accurately or responsibly...
My best advice to you is to try to be at the weight you think you can maintain over the long term at the time of your surgery. This will make the chances of significant changes in your weight affecting your outcome as small as possible.

It is difficult to say what your breast would look like after weight gain. I guess it would depend on how much weight you gained. Regardless, I like patients to control weight for their overall health in addition to trying to maintain their cosmetic result. Significant weight gain can negatively affect the outcome of a good cosmetic result.
