Belly button stitches after a tummy tuck should be removed only when your surgeon feels the umbilical incision has healed enough. If they are non-absorbable external sutures, many surgeons remove them around 7 to 14 days, but timing varies with skin circulation, tension, scabbing, drainage, smoking, diabetes, and exactly how the belly button was repaired. Some sutures are absorbable and are not meant to be pulled out. Do not remove them yourself unless your surgeon has specifically instructed you and shown you which stitches to remove. Removing them too early can let the small incision separate or widen the scar, while leaving certain non-absorbable sutures too long can cause irritation or stitch marks. Call your surgeon's office for the exact timing, and seek prompt care if there is spreading redness, increasing pain, drainage, odor, fever, black or dusky skin, or wound opening.
