Gaining weight after BBL?

Hello .Thank you for your question
You still in your healing period To see the Final results it will take 6-12 months for all the swelling to subside. 
after a BBL leads to  fat loss . We know that no matter what the patient will do lose 30-50% of the fat volume injected over 3-6 months after the surgery.
I personally believe that pressure in the early post op period (first 10 days after surgery) can affect the shape so I recommend not to sit on the butt for 10 days.
Good Luck

Dear ChissC,I instruct my patients not to sit for 2 solid weeks. We provide them a specialized pillow that our patients can sit on during that time. They can sleep on their stomachs or sides. But every plastic surgeon has his own postoperative protocol which he recommends to his patients. I would suggest you to discuss this with your plastic surgeon.Daniel Barrett, MD, MHA, MS

Thank you for your question. Patients can return to light activities almost immediately after surgery, normal activities 2 weeks after surgery, and vigorous exercise 4 weeks after surgery.  We usually experience a slow steady improvement for 3 months or so after surgery.Every surgeon will have his/her own preferences as to recovery for specific procedures. My patients do not have any sitting restrictions.  The pressure caused by sitting is not sufficient to affect viability of the fat cells and so the postsurgical position depends basically on comfort and any other operations that have been performed. 

Hello Dear.
Thanks for your question and provided information as well.
I have to say that you are still early on healing process, it is too soon to determine how your results are going to be, swelling for example is normal at this moment. I recommend you to wait and keep using your post surgical garment. Talk to your PS for any doubts in regards to your case.
Good Luck.-

I recommend my patients not to sit for the first two weeks after surgery. Then, a special BBL pillow can be used for short durations. Most patients return to light daily activities a few days after surgery and resume normal activities in about a week. Consult your surgeon since each surgeon has a slightly different protocol.

There is no data that says that sitting after a BBL leads to more fat loss compared to not sitting on the fat. We know that no matter what the patient will lose 30-50% of the fat volume injected over 3-6 months after the surgery. I personally believe that prolonged pressure in the early post op period (first 10 days after surgery) can affect the shape. It makes it more boxy and less round. This is not scientific by any means...just what I have learned since I started doing this procedures. If you start a workout regimen after the surgery that is more intense than before the surgery, you will lose some of the excess fat that was injected into your buttocks/hips. 

Congratulations on your recent surgery and thank you for sharing your question about your post operative recovery and results after your surgery.  Final results can take 6-12 months for all the swelling to subside.  At our office we actually see all of our surgery patients the very next day after surgery and then again at two weeks and beyond. We enjoy staying closely connected to our patients and enjoy giving the extra attention and service. Your concerns are important to discuss directly with your board certified plastic surgeon.  He or she will appreciate the open communication and will want to help you. I hope this is helpful and wish you all the very best.  Sincerely, Brian S. Coan, MD, FACS
