Help, why is my butt so flat after my Tummy Tuck?

Just a tummy tuck on the front cannot change the shape of your buttock.  Liposuction in the area could flatten it.  Review with your surgeon what they did.  Ask to look at your preop photos which likely they did and compare.  

This depends on what exactly was done in surgery, whether a circumferential TT, vs. just lipo in this area.  If just lipo to the lower back, there may be just some swelling to this area that needs to resolve and you curve will come back. If circ TT, then will have to see result in the end, and some lipo may be benefitial in the lower back.Hard to tell without photos.Best Wishes, PAblo PRichard, MD
