If a dissolvable stitch doesn't dissolve, it typically means it will remain in place and may need to be removed by a healthcare professional. While designed to break down over time, occasionally, stitches—especially those on the surface of a wound—do not fully resorb into the body.
Dissolvable stitches, also known as absorbable sutures, are made from materials that the body can naturally break down and absorb. This process usually takes approximately 6 to 8 weeks for the stitches to fully dissolve, depending on the type of material used and the location of the wound. They are often used for internal incisions or in areas where stitch removal would be difficult or traumatic, such as in children.
Why Stitches Might Not Dissolve
The primary reason a dissolvable stitch might not dissolve completely, particularly those visible on the skin's surface, is due to their exposure to air and fluids, which can interfere with the dissolution process. When they remain on the surface, they lack the moist, internal environment necessary for optimal breakdown.
When to Seek Medical Attention
It's important to monitor your stitches as your wound heals. If you have dissolvable stitches and they have not dissolved within two weeks, it's advisable to contact your healthcare provider.
Action to take:
- Consult your GP: If your dissolvable stitches are still visible and intact after two weeks, you can arrange an appointment with your GP practice.
- Simple Removal: A healthcare professional can easily remove these lingering stitches. This is usually a quick and painless procedure.
Leaving undissolved stitches in place for too long can potentially lead to minor irritation or, in rare cases, become a site for bacterial growth if not kept clean. Therefore, professional removal is the best course of action if they don't dissolve on their own.
Dissolvable Stitch Timeline & Action
Understanding the expected timeline can help you know when to seek advice.
| Timeframe | What to Expect | Action If Needed |
|---|---|---|
| Up to 6-8 weeks | Stitches gradually dissolve and are absorbed. | Usually no action required, continue wound care as advised. |
| 2 weeks or more | Stitches, especially surface ones, may still be present. | Contact your GP practice to have them professionally removed. |
| Beyond 8 weeks | Stitches should be fully dissolved. | If any are still present, ensure they are removed to prevent irritation or other issues. |
For more information on wound care and stitches, you can consult reliable sources like the National Health Service (NHS) or the Mayo Clinic.
