Belly Button Odor After Tummy Tuck

Sometimes after an abdominoplasty the scar around the navel contracts leaving the opening too tight and small in circumference.
The body naturally sloughs skin and debris, but in a contracted area that is hard to get to, this build up of dead cells can be a good place for bacteria to hide and grow.
Don't be afraid to vigorously cleanse the area with a cotton tip applicator stick and some anti bacterial astringent.

You can use a Q-tip to clean out your belly button gently with antibacterial soap. At this point in time so long after your surgery, your incisions should have closed up already so there should be no risk of affecting your tummy tuck results. If you're concerned, please see your surgeon.

An unusual smell from the umbilical region months after a tummy tuck may represent a retained sutures that needs to be removed.  Go see your surgeon for an evaluation.
