I had liposuction, and wearing a medical compression garment. how long i should wear this?

Usually 6 weeks or s: Your surgeon must have advised you about that.On an average 3-6 weeks.

I like six weeks: I've always preferred to keep my patients in garments for about 6 weeks. Many patients learn to like to like the extra support and will keep them on longer.

Liposuction: I usually recommend 6 weeks. http://vipplasticsurgery.com/body/#liposuction.

Surgeon's choice: I would follow the advice of your plastic surgeon who performed your surgery. The longer the better really. :).
