Why is My Stomach Still Uneven 4 Weeks After Liposuction?

It may take three to six months to see the final result of liposuction. An experienced surgeon examining you can make the best assesment, however your photograph suggests that there is an uneven "step off" at the edge of the suctioned area and too much residual tissue around the belly button. I would make sure that any surgeon you choose is certified by the American Board of Plastic Surgery and is experienced in liposuction. You will probably want a revision to get the most out of your choice to undergo liposuction.

It looks as though you had liposuction of the lower abdomen, but not the mid/upper abdomen or hips.  Frequently, it is necessary to add a few scars to get to the area around the belly button and to transition into the hips.  Once the tissues have softened, you may need a revision which would include those areas.  Then, hopefully, there won't be a noticeable stepoff, and the result will look more natural.
