I am 6 weeks post opp, I had Brazilian butt lift, liposuction the back and flanks and a tummy tuck.

Brazilian Butt Lift recovery time is dependent on how the patient’s body reacts to the procedure. Patients usually return to work after a week but you should not sit without the use of cushions for at least two weeks and you must wear a compression garment for several weeks after the procedure. You should wait until at least 2 weeks after the procedure to engage in sexual activity. Swelling and discomfort normally fades at six weeks. After about a month you will be mostly healed and you can get a nice idea of the permanent results after around six months.

Hello dear!!
Thanks for the question and provided information as well.
Every doctor has their preferences in regards to compression garments. I suggest my patients to use a full body compression garment (that closes with clips), 24/7 for the first 3 months, and after that, for 12 hours a day for 3 more months, to get the best results.
It is important for the compression garment to be very tight, for it to help with the swelling, after surgery, and to use it with a cotton t-shirt underneath to avoid garment burns.
You are still early on the healing process, it can take up to six months to see your final results, so please be patient​.
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 :)

I think these are all good questions but at this point you should ask your surgeon these specific questions because every surgeon is different. 

Hello thande,Thank you for your question.1-If your surgeon use dissolvable stitches there should had been dissolve by now, if not just have them take them off in your next follow up. 2- The longer you wear your garment the better the results. 3-Well the transfer would always have a percentage of fat they it would died is a cell the died in the transfer or after.

Hi DEar:The stitches if your doctor told you that they will fall by themselves, they can fall out in 4 weeks if not try to communicate with your PS, yes you have to continue wearing your compresion garment at least for two months, 3) all patients lost 15-25% of the fat transfer to the buttocks, it does not matter if you sleep or not on your back.Hope help you. It was a pleasure to answer your question. Good luck.Dr. Silvia AvilesDominican Certified Plastic Surgeon
