Garments are important after liposuction. They should be strong garments, and I find the spanx and biker shorts not as effective as medical grade garments.
Why do you need compression?
1. Swelling and bruise. When you are up on your feet, particularly if you had liposuction of the thighs, you will get swollen. Every patient is different in how much they swell. Bruising is related to this as well--a little bit of pressure keeps your blood vessels compressed to help those teeny tiny vessels stop oozing. You will heal faster when you swell and bruise less.
2. Shaping. Unclear if garments help with the overall shape, but as your skin is forming scar to the underlying tissue, I like it to do so in the place I want it and smoothly.
3. Future swelling / ie why do you make me wear them for a month? When doing liposuction you impair your body's ability to get rid of swelling AND you make it so it swells more easily. If you get dull, achy, throbby pain after being on your feet all day it is a sign you are swollen. Garments help by helping prevent the swelling from occurring in the first place. All my patients want to get moving as quickly as possible. Don't return to normal exercise routine until your swelling is completely gone.
Good brands: I like design veronique garments and sigvaris support hose. Get 30-40mm pressure hose if you did your calves as part of the liposuction procedure.
