How Will Gaining 10 Lbs Affect my Breast Implant Size?

Hello. Changes in the sizes of your breasts do to weight gain are unpredictable and depend mostly on genetics. That being said if losing weight made your breasts smaller then gaining weight would most likely make them grow. I recommend that my patients be at their target weight before surgery for this reason. I recommend that you maintain the weight you’re at. Gaining weight would be bad for your health with or without implants.

At your height and weight a 32DD should look very good. Gaining the 10 lbs could increase visible size of breast. If it does you may be faced with a choice only you can make, if you are happy with the current look I would suggest not gaining the extra weight.

Some women can gain and lose weight and see no change in their breast size. For others, the body and breast weight seem to be directly linked. Your recent history is probably a good barometer of what might happen if you are to gain the extra 10 lbs. Most patients don't see significant changes with only a 10 lb weight fluctuation. 

Typically 10 pounds of weight gain will not affect your result especially if your natural breast shape does not change with weight loss.

A lot of factors will affect breast size - weight gain/ loss, pregnancy, periods, etc.  Some people can gain or lose 4-5 pounds and all of it is in their breasts, some can gain or lose 30 pounds and none of it is  in their breasts.  You know better than anyone how your breasts will respond to weight gains and losses.

  If you lost 10 lbs and lost a cup size, a 10 lb weight gain will likely produce a cup size gain.  This is a mere educated guess.

The volume of the breasts can change overall weight gain in the body. 10 pounds of weight gain usually won't make too much difference. Nevertheless, it's all in the genes.

The effects of weight gain is difficult to predict. If you noticed changes to your breasts with the weight loss, you may have modest gains to the size of your breasts with weight gain.

With a weight gain, I would expect a modest enlargement of your breasts to a similar degree corresponding to the amount of breast tissue “shrinking” you saw with your weight loss.  Because the difference between an A and a B cup is smaller than the difference between a D cup and a DD and a DDD, I wouldn’t imagine that you will have a problematic change with weight fluctuations.

I think you answered your own question already. You stated that you dropped a cup when you lost 10 lbs.  It sounds like you may gain a cup or less with a 10 lb gain.
