Will I lose weight once the water retention has gone and last bit of swelling?

swelling takes months to go away and liposuction rarely equates to a true "weight" loss unless you diet aggressively after treatment. you will see "contour" changes.
If you are unhappy with your results please speak to your physician and ensure he was a full body VASER HD liposuction physciain wtih expensive experience in body shaping and not just traditional fat reduction.  At this point you should be using compression, RF treatments like venus legacy / exilis ultra / inmode forma or contoura and lymphatic massage to get you through healing.   We always add shock wave therapy such as cellutone, z wave, and eclipse evive to help prvent scar tissue formation and ensure an even and smooth result. It will take 6-12 months to see the final outcome.   If you are unhappy you can get a revision procedure by an expert in VASER HD lipo.  Best, Dr. Emer.

Unfortunately, liposuction is not weight reduction surgery. Instead, liposuction helps sculpt the body by taking away fat from unwanted areas. You are in very early stages of recovery following your surgery and are bound to have a lot of tissue swelling. Once the swelling has settled in about 3 to 6 months, you will appreciate the reduction in volume of fat in the treated areas.
