Three and a half months after abs/flanks lipo and no results. Increase in circumference. Is this normal?

With an increase in size, you should consider the possibility of fluid collection as well as swelling.

At this point, you most likely have some swelling which can last 3-6 months. Due to your description, I recommend following up with your Doctor for a formal evaluation. I suggest adding hyperbaric oxygen and lymphatic massage along with your compression to help decrease swelling. To improve your final results, I also recommend adding vanquish for further fat removal, exilis/venus legacy for skin tightening, cellutone/z wave to make the skin smooth, remove scar tissue, and improve the skin’s appearance. Best, Dr. Emer

Thanks for the question, as a surgeon I can tell you we truly care about our patients results and happiness. It would be best to go back and share your results with your doc and the two of you can work together to find the best solution

There are many variables that can relate to your concerns.
The best one to determine the measurements diference is 
the person that did them before the procedure. It is also 
important to compare the weight before and after surgery. 
Your plastic surgeon should be able to answer your concerns.
Best wishes.

The increase of the circumference may be due to swelling or fluid collection in your abdominal region. Usually it takes 6 months for the swelling to fully subside, but at this time it should have already decreased. It is advisable to follow up with our surgeon to eliminate the possibility of a fluid collection or infection.

Sorry to hear that you have concerns about the results of your procedure.  While swelling a few months after surgery is normal, the increase in your waist size is notable, and it raises the question whether there is some other explanation.  One possibility is that after liposuction you developed a fluid collection or seroma, and sometimes after a few months, these collections develop a wall or a bursa.  The first step is simply to discuss your concerns with your surgeon, and if there is any concern of a fluid pocket, they may want to consider an ultrasound.  Best of luck.
