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

I'm 22 years old, 5'2" tall, and weigh 115lbs. I'm a 34B and really do not want to get implants so I've decided fat transfer is my best bet to get up to a C cup. I'm also getting personal training at the moment and will be losing weight and gaining muscle in the next couple of months. Should I get the procedure sooner rather than later? I'm worried that the surgeon will not be able to extract enough fat for the desired result but have also heard it's better to lose weight before this surgery.

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.

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.

Obtain a stable weight and then seek out a plastic surgeon with a reputation for performing these procedures effectively in thinner patients.

Should I lose weight before fat transfer to my breasts?

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.
