3rd day post tummy tuck, what happens if I don't wear my girdle?

Thanks for your question.  We use "binders" or "girdles" to compress the tissue as to decrease swelling and fluid accumulation.  It can also provide support to the muscle repair that was just performed.  If you are uncomfortable in your binder, you should talk to your surgeon to see if there are any better options or tweaks that can be made.  Congratulations and best of luck to you.  

The purpose of the compression garment, or girdle, is to help the swelling subside as quickly as possible.  Additionally, it helps to prevent further buildup of fluid underneath the skin flap.   Congratulations on your recent procedure.   Occasionally, there are discomfort issues with the girdles, and your plastic surgeon will be able to address these concerns and potentially change compression garments.   Best to you during your continued recovery.
