How do I maintain fullness in buttocks and decrease swelling in abdomen?

Hey there,I presume you have undergone Fat grafting to your “Butt” and the graft has been harvested from the abdomen. Please allow three months for the stiffness in the abdomen to settle. Post liposuction it would take three months for an area to return to actual contour. Swelling / Induration(stiffness) and discolouration would all take three months to normalise. It is now 4 weeks and if the fat grafts have not vascularised (got its blood supply) then they would not survive no matter what. May be the swelling and inflammation is settling down. You cannot do anything to maintain or increase the size. 
Hope this helps.

Hello and thank you for your question. I'm not sure what procedure you have gotten done, but in most procedures, you will have to wait a couple months to allow the swelling to decrease. In order to maintain fullness in your buttocks, gluteal exercises can help. However, please wait to do any exercises until your physician states it is okay to do so. Although the compression garment may be causing your buttocks to look smaller, is necessary to decrease the swelling post-operatively. Please wait a couple of months to see your final results. If you are still dissatisfied, you can get a Brazilian Butt Lift to make your buttocks appear larger and more shapely. Eating a healthy diet is always a good thing to do. Best wishes!
