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

Its too early at this point for you to see your final results.  I am assuming that your tummy tuck scar stops at your hips and does not go all the way aorund your waist.  This is temperary from swelling and should resolve. Maintain a healhty lifestyle for best results.  Best of Luck. 

You are so early after surgery that there is swelling which is obscuring your view.  If the butt was not specifically operated and you just had a tummy tuck with liposuction of the hips, then you should have return of the contours of the butt.

If you did not have a circumferential tummy tuck or liposuction to the buttock area then the flatness that is concerning you should be temporary. I encourage you to discuss your concerns with your surgeon so that you can feel comfortable and confident in your recovery.

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.
