Why is it important to sleep in an upright position after a breast augmentation??

I don't tell my patients to sleep upright because it makes no sense. Either the pocket is created correctly, or it's not. Most smooth walled implants, when placed under the muscle will want to ride high for a little bit due to the tension in the overlying muscle. As the muscle relaxes, the implants will drop naturally into the space created for them. In my opinion, the only thing that can inhibit that from happening is a bra that's worn too tightly with a underwire. Hope that's helpful.

I actually don't think it is very important at all.  I usually tell my patients to sleep with a couple extra pillows if they can tolerate it.  If it is in the least bit uncomfortable or annoying, it's not going to make any difference in the long-term anyway.Best of luck!

Thank you for your question.  You should sleep on your back with your head elevated for the first four to five days after surgery to reduce your discomfort and swelling.  You can sleep on your side or stomach after four to five days or when you feel comfortable. Happy healing!  :)
