Is it true that you can't lay on your side and have to wear a bra once you get implants?

Dear Vanish66,
every surgeon has a preferred type of bra that they let their patients wear after breast augmentation, as this would depend on various factors like the type of surgery performed and the size of the implant used. You should discuss your concerns with your plastic surgeon and follow his or her advice.

Many surgeons will ask you to sleep on your back during the healing process following breast augmentation. Most will allow you sleep on your side once an appropriate period of time has passed. Wearing a bra regularly is recommend whether you have implants or not. Bras help to counteract gravity and reduce the tendency for breast to sag over time.

After about 6 weeks, I cannot think of a reason not to lay on your side after gel breast implants. Although every surgeon has their own protocol after surgery, in my experience of 18 years, bra use to support the implant is usually started after the implant has settled a bit. Once the implant is in position, then I strongly recommend locking it in with a good supportive bra for 6 months. After that, I leave it up to you as to how much bra support is comfortable. All the best!
