How Long Do Absorbable Stitches Typically Last?
Absorbable stitches, also called dissolvable stitches or absorbable sutures, are designed to provide temporary wound support and gradually break down inside the body. Depending on the suture material and surgical application, complete absorption may take anywhere from a few weeks to several months.
Some fast-absorbing sutures may disappear within approximately 14 to 42 days, while long-term absorbable sutures such as polydioxanone may take around 180 to 210 days to be fully absorbed. (Sutures Manufacturing Company in India)
It is important to understand that loss of tensile strength and complete absorption are not the same. A suture may lose most of its wound-support strength before the material has completely disappeared from the body.
What Are Absorbable Stitches?
Absorbable stitches are sterile surgical threads manufactured from natural or synthetic materials. They are used to approximate tissues, close wounds and support healing without requiring routine removal.
Synthetic absorbable sutures generally break down through hydrolysis, in which water within the body gradually degrades the material. Natural absorbable sutures, such as catgut, are mainly broken down through enzymatic activity.
They are commonly used for:
- Internal tissue closure
- Subcuticular closure
- Gastrointestinal procedures
- Gynaecological surgery
- Oral surgery
- Paediatric procedures
- General soft-tissue approximation
How Long Do Different Absorbable Sutures Last?
The absorption period varies according to the suture material.
Polyglactin Rapid Sutures
Rapidly absorbing Polyglactin sutures are intended for tissues that heal quickly. They lose strength relatively early and are generally completely absorbed within approximately 42 days.
They may be considered for superficial wounds, mucosal closure, oral surgery and other rapidly healing tissues.
Polyglactin 910 Sutures
Polyglactin 910 is a braided synthetic absorbable material that provides intermediate wound support.
It is commonly used in general surgery, gynaecology, gastrointestinal surgery and soft-tissue approximation. Complete absorption generally occurs over several weeks.
Polyglycolic Acid Sutures
Polyglycolic acid, commonly known as PGA, is a braided absorbable material that provides dependable handling and knot security.
PGA sutures normally provide temporary wound support and are gradually absorbed over approximately two to three months.
Poliglecaprone 25 Sutures
Poliglecaprone 25 is a synthetic absorbable monofilament suture. It offers high initial tensile strength and smooth tissue passage.
It is commonly considered for subcuticular closure and general soft-tissue approximation. Complete absorption may take approximately three to four months.
Polydioxanone Sutures
Polydioxanone, also known as PDS or PDO, is a long-term absorbable monofilament suture.
It is suitable for tissues requiring prolonged support, such as fascia and other slower-healing tissues. Complete absorption may take approximately 180 to 210 days. (Sutures Manufacturing Company in India)
Catgut Sutures
Catgut is a natural absorbable suture available in plain and chromic varieties.
Plain catgut is absorbed more quickly, while chromic catgut is specially treated to provide longer tissue support. Absorption time can vary because natural materials are affected by the individual patient’s tissue response.
What Affects the Absorption Time?
The time required for absorbable stitches to disappear can depend on:
- Suture material and construction
- Size and thickness of the thread
- Location of the wound
- Blood supply to the tissue
- Presence of infection
- Patient health and healing response
- Surgical technique
- Type of procedure
Visible dissolvable stitches used on the skin may loosen or fall away earlier, while deeper internal sutures can remain inside the body for several months. NHS patient guidance also notes that absorption time varies and that some stitches may take several weeks to disappear completely. (UHS Sussex)
Do Absorbable Stitches Need to Be Removed?
Absorbable stitches usually do not require removal. However, a small exposed portion may occasionally remain after the wound has healed.
Patients should not pull, cut or remove a remaining stitch themselves. A healthcare professional should examine it if it causes irritation, discomfort or does not disappear as expected.
When Should Medical Advice Be Sought?
Medical advice should be obtained if the wound develops increasing redness, swelling, severe pain, discharge, bleeding, fever or begins to reopen.

Conclusion
Absorbable stitches can last from a few weeks to several months. The exact duration depends mainly on the suture material, tissue type and required wound-support period.
Selecting the appropriate absorbable suture helps provide sufficient support during healing while allowing the thread to gradually break down without routine removal.
