What should you know about black dissolvable stitches?

Suture material comes in different colours. A dark or black thread may be chosen so clinicians can see it clearly against the skin. Dissolvable means the body gradually breaks the material down; it does not mean the thread disappears immediately. A small thread end may remain visible while the wound strengthens.

The stitch colour alone does not show whether healing is going well. Look at the surrounding skin and the wound instead. Mild tenderness, tightness or a little clear fluid can occur after suturing, while spreading redness, increasing warmth, thick discharge or worsening pain deserves assessment.

Follow the dressing instructions you were given and keep the area clean and protected. Wash your hands before touching it, avoid pulling or trimming the thread, and do not soak the wound until a clinician says it is suitable. Reduce rubbing and strenuous movement if they place tension on the wound. Do not apply creams, alcohol or antiseptic products unless advised.

If a stitch loosens, catches on clothing or becomes buried, arrange advice rather than trying to remove it yourself. The type of suture and the location of the wound affect follow-up. Read more about Surgical Sutures and Wound Care and Dressing.

Seek prompt medical care for spreading redness, increasing swelling, severe or escalating pain, pus, fever, red streaks, heavy bleeding, loss of feeling, or a wound that opens. Get urgent help if bleeding does not settle with firm pressure or if you feel faint or seriously unwell. A dirty or puncture wound may also need tetanus advice.

Ask which suture material was used, how long the thread may remain visible, whether your dressing can be changed, and which wound changes should trigger review. You can also ask whether your tetanus vaccination is up to date and whether the wound needs a planned check.
