Should I lose weight before or after fat transfer to the breasts? Will my breasts deflate if I lose weight after surgery?

Thank you for your question. About 60-70% of the grafted fat survives.  At 6 months you will have a good idea of your results. Some women have a second or third procedure which continues to increase your volume safely. The best way to assess and give true advice would be an in-person exam. 

For health and safety reasons, best to be at a BMI less than 30 or within 10 pounds of your goal weight and stable at that weight for 6 months prior to surgery for optimal results.

Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery. Best of luck! Dr. Schwartz Board Certified Plastic Surgeon #RealSelf100Surgeon

if you are considering fat transfer to your breasts I recommend going in for an evaluation by a board-certified plastic surgeon before losing weight and attaining your goal weight. Many times it takes more than one fat transfer session to gain the results that you're  wanting to achieve. Sometimes it's not even possible to achieve the results that you want with fat transfer alone and implants may be preferable. In either case it's best to be evaluated so that you can have an in person examination to determine if you're a good candidate for either procedure. Good luck !

It would be best for your weight to be stable prior to surgery. I would recommend loosing all the weight you want, then consider the surgery. You will need donor fat for the surgery to be successful.

Thank you for your question. Based on your description, you may benefit from fat transfer. Fat is living tissue and, like a farmer planting seeds in a garden, requires even distribution to maximize its survival. This is also, likely, very technique dependent. Fat can be unpredictable with regard to its volume, however, once integrated into the tissues, it has the potential to last a lifetime. Based on the volume available and the parameters of your breast, you may or may not experience significant changes in your final outcome. Brava expansion may be necessary to provide additional volume retention, however, this modality is currently not available as the company is no longer producing the domes.
I would certainly encourage you to be near your ideal body weight for fat transfer and not gain weight as is often suggested. Fat cells are not unlike balloons where a fixed number exist. Gaining weight only serves to increase the volume of the balloons and not their number. This would actually make heavier patients less ideal for transfer as it would leave them with a fewer number of larger balloons rather than a greater number of small ones which would be ideal. I would certainly recommend that you visit with a board certified plastic surgeon who is experienced in all these matters. I hope this helps and have a wonderful day. Dr. Kayser - Detroit

Thank you for your question.  If you plan to lose weight it is best to lose it before  breast surgery.  Losing weight after breast surgery can change your result because the breast contain a significant amount of fat and with weight loss the breast can become smaller and sag.  This includes transplanted fat thus he should not lose weight after a fat transfer to the breast or your breasts will lose volume.
