What happens if a wound heals with stitches in?

If a wound heals with stitches still in place, it can lead to complications such as infection, scarring, and delayed healing. The stitches may cause irritation or be rejected by the body, leading to further complications. It's essential to have stitches removed at the appropriate time to ensure optimal healing and minimize risks. If stitches remain too long, they can become embedded in the tissue, requiring more invasive removal.
