6 weeks post BBL. When can I lay on my back?

Hello and thank you for your question. You should double check with your surgeon about when you can lay on your back.  My own protocol is as follows: expect to be sore for 5-10
days, no heavy lifting for 2 weeks, and your bruising (if any) will
resolve usually by 3 weeks. I like my patients to wear a pressure
garment for 3 months. Some surgeons say you can't sit on your buttocks
for 2 months, but I think there is no science to back up that
recommendation, and I have my patients sitting within a few days and our
fat grafts seem to do pretty well. Remember that each surgeon has
their own protocol and please follow the instructions of your particular
surgeon catered to your individual needs. Be sure to seek consultation
with a board certified plastic surgeon with expertise in advanced body
contouring techniques. I hope this helps!Dr. Sean Kelishadi

I usually allow patients to lie on their back after about 2-3 weeks provided that they do not stay in one position too long. Best to ask your surgeon.
