Lumbar vs flank. What's the difference?

Largely they describe the same area, the fatty rolls behind the love handles.  Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search. 

Thank you for your question.
I expect that both surgeons are referring to the same treatment area. An important point is to be sure you and the surgeon agree as to which areas are to be treated.
All the best,

Thank you for the question. I recently wrote the procedural and safety guidelines for plastic surgeons on liposuction. The entire paper can be found on my website of you are interested. Essentially the waist is a female term hah refers to the side from the ribs to the hip bone. The same area in a man is called the flank. They have different names because they should look different (curve vs a box). Lumbar is referring to areas around the spine. I still debate with surgeons over arbitrarily charging for areas as everyone is different in size and shape. I believe surgery makes sense when charged per time similar to other professionals
