Fat loss after bbl - Can my fat die because it’s looking flatter to me. Pls can you advise what I can do to plump it up again.

Patients loose between 30-70% of volume of fat grafts in the course of 6-8 months after surgery. After that time remaining volume is permanent since that is patient own fat and behaves as fat in the rest of body; if patient gains weight grafted area will proportional increase in volume and vice versa. It is unlikely that you are loosing fat 2 years after fat transfer. Hope this helps. Good luck.

Thank you for your questions. I would discuss your concerns with your surgeon, but usually by 6 months, whatever fat is going to survive the transfer is there to stay. So at 2 years, if you are seeing ongoing changes in volume, it likely has nothing to do with your surgery. Best of luck!Dallas R.

About 50% to 75% of the fat survives after the BBL as the literature has demonstrated. Thus, results are PERMANENT after the first few months.Kenneth Hughes, MD, ABPS Board Certified Plastic SurgeonLos Angeles, CA

Hello dear!!
Thanks for the question and provided information as well. 
After a BBL, only about 70% of the transferred fat cells will survive, so it is normal to see a minor reduction in your buttocks. If you have any concerns, I suggest you to follow up close with your plastic surgeon.
Good luck :)

Hi and welcome to our forum!
The fat grafts placed two years ago are now part of you and will not undergo changes or damage due to body position. 30-50% of the graft may resorb after placement within the first month or so, but any later volume reduction is unlikely...UNLESS you lose weight. Postoperative weight loss will significantly alter the result. 
Your buttocks now also may be looking relatively smaller because the surrounding tissues are most likely swollen from your recent abdominoplasty and liposuction 3 weeks ago. 
Continue followup with your plastic surgeon and reassess your status at 6 months out from surgery.
Best wishes...

Unfortunately, traditional techniques of harvesting fat result in nearly half of the fat being traumatically injured. In contrast, VASER liposuction allows for near 90% fat viability. As a result, we observe near complete take of the fat transfered to the buttocks. If you are going to redo your BBL, make sure that you complete a virtual consultation with a BBL specialist so that you can appreciate the difference that VASER liposuction will make for you.

you're fat cannot die by you looking at it or it looking flat.  I typically ask patients to not sleep on their back for the first three weeks after a BBL. At that point any fat that is going to survive has already done so and the fat that is not going to survive it's already dead.  Other plastic surgeons will have their patients sleep facedown for a bit longer. Nobody asks patients to not sleep on their back for two years.  It would've perhaps been ideal to use the fat removed during your recent liposuction to add volume to your now flatter buttocks.  There's nothing you can do to improve or worsen the shape of your bottom other than surgical intervention.  Best, Mats Hagstrom MD
