1 Week After Tumescent Lipo and I'm the Same Size, How Long Should I Expect the Swelling to Last?

This sounds normal, especially so soon after your surgery. Most of the swelling will be gone in 2-3 weeks, but some firmness can last for a couple of months. You can assess your results at about the three or four month mark. You can try massaging the area with your surgeon's advice.

                  It’s
not unusual to have significant swelling following tumescent liposuction.  This can occur for a variety of reasons
including the administration of tumescent solution, I.V. fluids, and the bodies
tendency to retain fluid whenever injured.  This fluid retention can result in
significant weight gain and in some cases obscure the results of liposuction.

                  In
the vast majority of patients swelling resolves in 3 to 4 weeks following
surgery.  Although it’s unusual, in
rare cases it may take as long as 3 to 4 months.  When patients have sustained swelling, they should be
evaluated by their surgeon.  Their
surgeon should be able to formulate a treatment plan to help improve their
symptoms.
