30 days post op —& Lipo 360 + BBL

Thank you for your question. Not sitting after 4-5 weeks does not make a difference on the overall long term fat and volume size. 50% of the fat transferred absorbs. Full results show within 6 months.

I recommend that my patients minimize sitting, even with a pillow, for the first two weeks.  If they must sit, every 30 minutes or an hour, they should get up and stand for a few seconds to take the pressure off.   This reduces the chance for fat necrosis. I usually recommend about 6 weeks before sitting without a pillow. After 6 weeks the fat has revascularized, and they will have a very good idea of their final results.  Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Hello. Thank you for your question. After fat grafting it's very important not make excessive direct pressure over the butt or hips area.  The boppy pillow is a very good idea that you can consider after a BBL.  After 4 weeks most of the swelling will be gone and and the fat cells that finally survived will no longer be affected by the pressure of sitting on your butt or hips. 

After a BBL, 30-50% of the fat volume injected is lost over the first 3-6 months after the surgery. There is no literature to show/support that not sitting on the fat (buttocks) actually allows for more survival. I ask my patients to refrain from sitting or laying on their buttocks for 10 days to help maintain the shape. Not sitting does not make a difference on the overall long term fat volume/size. The fat "dies" because it did not receive the proper nutrients such as oxygen from blood flow. It is decided after 6+ hours which fat cells will not make it. The body takes months to fully absorb the fat that "died" and that is why you continue to see shrinkage over 3-6 months. I too have patients that choose to not sit or lay on their buttocks for months, but this is not necessary. I explain that it doesn't help but it won't hurt to stay off of the buttocks pas the 10 day mark. Remember always follow your PS post op recommendations.
