3 weeks post op Tummy Tuck, my butt is flat! My whole back side looks like a flat board. Will my butt return?

Without photos it is hard to comment on your question. I'm not sure how your back and buttocks became flat from a tummy tuck. You'll find that different surgeons have different approaches to a TT. Some do some liposuction, others do extensive liposuction. In my practice, my approach is to address the whole midsection of the person. This means liposuction of the abdomen, back, waist ,hips, fat grafts to the buttocks and a TT. In my opinion, if one does a TT with minor liposuction of the flanks, you can end up looking flat and wide without much improvement in shape. Wait 4-6 months to heal, and see if your surgeon can address these areas for you to give you a more feminine shape. Good luck.

Good afternoon, You must give the recovery time to see if everything returns to normal if you did not receive a lower or circumferential tummy tuck can flatten them.
