Why Didn't my Doctor Tell Me to Wear a Compression Garment After Lipo?

It is likely that if small or moderate amounts of fat were removed by liposuction, a garment may not  make  a difference in the long run though I am not aware of a double blind controlled specific study to prove this.My suggestion is try a Spanx which will likely be more comfortable. A compression garment is recommended and beneficial after liposuction because:It restricts the amount of edema that forms and hastens its resolution by mechanical pressure.It decreases the amount of bruising.It assists the loose skin in retracting or shrinking.It is common to have weight gain due to edema, serum that collects in the area, and the tumescent fluid that was injected. This will resolve over time. The more you wear the garment initially, the quicker this fluid resolves.Edema: a condition characterized by an excess of watery fluid collecting in the cavities or tissues of the body.The length of time that the garment should be worn varies depending on the amount of fat removed, the elastic nature of your skin, how much loose skin remains, and other factors. Your surgeon would give you the best advice, however this is the general routine for my patients.The first garment should be fitted for you in the office prior to surgery and applied in the operating room. Often it will become loose as the edema is mobilized, and then it will need to be replaced. Spanx is a reasonable compression garment if it gives enough support and is the right size. I have my patents bring them in so I can confirm that it fits well.Most important advice is to listen to your surgeon, as he or she knows how much fat was removed, the elasticity that remains in your skin, and amount of skin redundancy.I recommend that my patients wear their garments for a minimum of three weeks full time then for twelve hours at a time (day or night). If there is not a lot of redundant skin, this continues to a maximum of six weeks.To be effective, the garment needs to fit snugly—but not too tight as that can make it difficult to sleep or cause pressure problems (inspect your skin when it is exposed if you are uncomfortable). As the edema resolves it is common for patients to switch to a smaller garment that fits. A Spanx-type garment would work fine, rather than ordering one or paying more at your doctor’s office. 

Hello dear!!
Thanks for the question and provided information as well.
I suggest my patients to use a full body compression garment, 24/7 for the first 3 months, and after that, for 12 hours a day for 3 more months, to get the best results. But every doctor is different and have their own protocols.
It is important for the compression garment to be very tight, for it to help with the swelling, after surgery. 
If you have any concerns, please follow up close with your plastic surgeon.
Good luck :)

Every surgeon has different guidelines regarding compression garments. Some don't recommend them, and others do. If your surgeon didn't recommend wearing one, then please ask them why. They probably have a valid reason.
