Should I see much results after 800cc was removed from lower and upper abdomen?

The first time i went for this procedure i had my lower back and side done not upper abdomen. I saw changes with my back and side but not with my lower abdomen. I was told i would have to do it again, i ended up doing my lower again and my upper abdomen. My doctor got 800cc of fat out. It didn't look like much. It has been almost 3 weeks and i look the same. I guess am not sure if 800cc is much to give me great results.
