What are the compression garments like after liposuction? If I can not tolerate spanx for very long, would that be a problem?

Patients are encouraged to maintain compression for 6-8 weeks post op (4 weeks full time and 2-4 weeks part time). Garments should be snug but not necessarily unbearable. They will initially be tight and will loosen as swelling subsides necessitating either a second stage garment or alterations. While different from Spanx, they are essentially the same thing only more intense (Design Veronique and Isavella are 2 major distributors)That being said, regimens and garments will vary from practice to practice. As always, discuss your concerns with a board certified plastic surgeon (ABPS).Donovan Rosas MD

Hi, thank you for your question. 
Compression garments are typically used after body contouring procedures including liposuction to alleviate the swelling and to help improve the final contour. They are similar to spanx. 
If you can't tolerate the spanx, and you understand that your results won't be optimal, it is not compulsory to wear compression. 
Consider an in-person consultation with a board certified plastic surgeon to go over which options will help you to reach your specific goals. 
I hope this helps. Best of luck!
