What are surgical sutures used for?

A clinician places stitches through or around the edges of a wound to hold the tissues in a stable position. This can reduce pulling on the healing area and help protect deeper tissue while the skin repairs itself. Some sutures dissolve gradually inside the body; others need removal after the wound has had time to close. The choice depends on the wound location, depth, tension, and the tissue being repaired.

Follow the wound-care instructions you were given. Keep the area clean and dry as advised, avoid rubbing or picking at the stitches, and limit activities that stretch the wound. Do not apply creams, antiseptics, or dressings unless your clinician recommends them. Keep any planned review or removal appointment, because timing varies with the body area and suture type.

Contact a clinician promptly if the wound opens, bleeding does not settle with gentle pressure, or pain, warmth, swelling, or redness is worsening. Pus, a bad smell, fever, or red streaks spreading from the wound can indicate infection and need assessment. Seek urgent help for heavy bleeding, severe pain, or sudden loss of movement or sensation near the wound.

Ask which type of suture was used, whether it dissolves, how to clean and cover the area, and which movements or activities to avoid. You can also ask when the wound should be checked and what changes should prompt an earlier review.
