BBL and also fat transfer to the hips - How to sit and sleep?

Your board certified plastic surgeon should give you specific instructions about how to sit and sleep after your surgery. Every surgeon is different in what they recommend. I would advise speaking to your surgeon to get their recommendations. I instruct my patients to sit and sleep a certain way for up to 8 weeks after their BBL

Hello dear!!
Thanks for the question and provided information as well. 
You can adopt the sleeping position that best suits you and in which you feel most comfortable, preferably on your stomach. It helps to use several pillows to accommodate yourself. Each doctor has their own protocol It is very important that you talk to him about your concerns and goals. I recommend my patients not to sit for more than 30 mins. every two hours, for the first 2 weeks, and always with the help of a boppy pillow. If you have any concerns, I suggest you to follow up close with your plastic surgeon.
Good luck :)

Every surgeon has different instructions.  It is best to ask your surgeon. In general, I tell my patients to avoid sitting in anyone position for too long for the first few weeks and limit exetion activity.
