Why is my abdomen so lumpy at 6 weeks post-op? (Photo)

It is too soon to tell what your final results will be. It actually takes about 6 to 12 months to see the final outcome. However, even at this stage, it's clear that you will likely will need a revision procedure -- this is simply not right.
I recommend following up with your physician about their suggested after care protocol. I have my patients wear compression for 3 to 6 weeks straight and then overnight for 3 to 6 months after their procedure. I also recommend that my patients receive lymphatic massage treatments every day for a week following their procedure; twice per week for the following month; and then once per week until healing is complete. To improve your final results, I suggest adding Vanquish for further fat removal; truSculpt iD, Exilis, Forma, and Venus Legacy for additional skin tightening; and Cellutone / ZWave to make the skin smooth, remove scar tissue, and improve the skin’s appearance.
Ultimately, if you are unhappy with your results, please speak to your physician and ensure that he/she was a full body VASER Hi-Definition Liposuction physician with extensive experience in contouring and body shaping -- and not just traditional fat reduction. You can always get a revision procedure by an expert if needed. Best, Dr. Emer

So... it's true that it takes up to six months for swelling to go down... so at six weeks you are still early in the process.  Lumpy and bumpy is very normal. I'd recommend daily massage as well as continued compression.  Also, HIVMAT and ZWAVE treatments would be highly beneficial.  Good luck and hope this helps!
