Therefore, it is recommended that patients remove the sutures in a timely manner according to the healing of the wound. 1.

If the suture is removed too late, the suture may remain in the body tissues, which will stimulate the surrounding tissues to develop inflammation and infection, resulting in localized redness and swelling. In severe cases, localized pus and abscesses may also form. 2. Scarring: and if the stitches are removed too late, it may lead to the proliferation of scars and overgrowth of fibers, resulting in the formation of tracks or spider-like appearance. 3. If the suture is not removed for a long time, after the wound tissue heals, there can be newborn tissue to bury the suture, so that the suture as a foreign body, may cause local redness, swelling, harassment and so on, and when removing the suture, it is also necessary to cut through the local tissue in order to find the thread. It is recommended to follow the doctor’s instructions, in the prescribed time to the surgical department in time for follow-up to remove the stitches, after removing the stitches, you should eat more vegetables and fruits rich in vitamin C, in order to promote the healing of the wound.
