How long after breast augmentation do I have to sleep with a bra?

Hello,Thank you for your question. Your Plastic Surgeon will need to be the one to answer that for you. I advise my patients to wear their post-surgical bra for 8 weeks, avoiding underwire bras during that time. Ask your plastic surgeon what they recommend for you.All the best

Thank you for your question.  In my practice I recommend that patients wear a light weight compression sports bra for four weeks (morning and night) following their breast augmentation.  With that said, not every surgeon adheres to the same postoperative instructions so I would recommend discussing proper use of your sports bra with your plastic surgeon directly.  I hope that you find this helpful and I wish you all of the best!

Usually 6 weeks is sufficient to stop wearing a bra during sleep. But I suggest you check with the surgeon that performed your surgery.

Every patient is different and surgeons have different feelings on the use of postoperative support brassieres. Often, a bra has several functions. It can be used to help maintain the surgical pocket that the implant was placed into. It also serves to hold gauze and other bandages to help pad the breast following surgery which some feel comfortable. Sometimes, just the mere fact of wearing a bra makes it more difficult to turn over in your sleep in the early time. Following breast augmentation. It is always wise to follow your surgeon's advice. He or she should have reasons to explain to the result. It is uncommon to have to wear a bra after five or six weeks.

The answer to your question should be obtained from your Plastic Surgeon that performed your surgery.  They will explain the reason and length of time expected of you to obtain the best result.  Good luck.
