If you’ve recently had surgery and gotten stitches that will dissolve on their own, you may be wondering – how long do degradable stitches last? The answer depends on a few key factors. Degradable or absorbable sutures are commonly used for many surgical procedures because they don’t require removal. Your body will naturally break down these stitches over time. Keep reading to learn everything you need to know about how long different types of degradable stitches last, what affects the absorption time, proper care instructions, and signs that your stitches may not be degrading properly.
The quick answer is that most degradable stitches take around 6 weeks to fully dissolve, but the exact time frame can range from 10 days up to several months depending on the location of the incision and type of suture material used. Sutures used internally tend to absorb faster while stitches on the skin’s surface take longer.
Types of Degradable Suture Materials
1. Catgut Sutures
Catgut sutures are one of the oldest types of degradable sutures. They are made from the submucosal layer of sheep or goat intestines. Despite the name, catgut sutures do not actually contain any cat parts. These sutures are known for their excellent handling properties and are commonly used in various surgical procedures. Catgut sutures typically start to degrade within 7 to 10 days and are completely absorbed by the body within 56 to 90 days.
2. Synthetic Absorbable Sutures
Synthetic absorbable sutures are made from materials such as polyglycolic acid (PGA), polylactic acid (PLA), and polydioxanone (PDO). These sutures are designed to degrade over time and are absorbed by the body. PGA sutures, for example, can start to degrade within 10 to 14 days and are usually absorbed within 60 to 90 days. PLA and PDO sutures have slower degradation rates, with absorption times ranging from 90 to 180 days. Synthetic absorbable sutures provide excellent tensile strength and are commonly used in various surgical procedures.
3. Barbed Sutures
Barbed sutures are a relatively new type of degradable suture that are designed to have small barbs or projections along the length of the suture. These barbs help to anchor the suture in place without the need for knots, reducing the risk of suture slippage. Barbed sutures are typically made from synthetic materials such as polydioxanone (PDO) or poliglecaprone (Monocryl). The degradation time of barbed sutures can vary depending on the specific material used, but they are generally absorbed within 90 to 180 days. Barbed sutures are commonly used in procedures where wound closure and tissue approximation are important, such as in plastic surgery or laparoscopic procedures.
Expected Absorption Time by Suture Type
1. Catgut Sutures
Catgut sutures are made from the submucosal layer of the intestines of sheep or cows. These sutures have been used for centuries and are known for their absorbable properties. The absorption time for catgut sutures can vary depending on the specific type used.
Typically, catgut sutures are expected to be absorbed within 7 to 10 days. However, it’s important to note that the absorption time can be influenced by factors such as the patient’s immune response and the location of the suture.

2. Synthetic Absorbable Sutures
Synthetic absorbable sutures are made from materials such as polyglycolic acid (PGA), polylactic acid (PLA), or polydioxanone (PDO). These sutures are designed to break down in the body over time and are commonly used in various surgical procedures.
The absorption time for synthetic absorbable sutures can vary depending on the specific material used. On average, these sutures are expected to be absorbed within 2 to 6 weeks. However, certain types of synthetic absorbable sutures can last longer, up to 6 months.

3. Barbed Sutures
Barbed sutures, also known as self-retaining sutures, have gained popularity in recent years due to their unique design. These sutures have small, sharp projections along the length of the suture, allowing them to “catch” the tissue and hold it in place without the need for traditional knot tying.
The absorption time for barbed sutures can vary depending on the specific type used. On average, these sutures are expected to be absorbed within 6 to 12 months. However, it’s important to note that the absorption time can be influenced by factors such as the patient’s healing process and the location of the suture.

Factors That Affect Absorption Time
1. Location on the Body
The location of the degradable stitches on the body plays a significant role in determining how long they will last. Different body parts have varying levels of blood flow, which can affect the absorption rate of the stitches. For example, stitches on the face or scalp may absorb faster due to the high blood flow in these areas, while stitches on the extremities like the hands or feet may take longer to absorb.
2. Tension on the Wound
The amount of tension on the wound can also impact the absorption time of the stitches. If a wound is under a lot of tension, such as in areas like the joints or where the skin is stretched, the stitches may take longer to break down. On the other hand, wounds with minimal tension may allow the stitches to absorb more quickly.
3. Infection
Infection can significantly prolong the absorption time of degradable stitches. When an infection occurs, the body’s immune response is triggered, resulting in increased blood flow to the area. This increased blood flow can slow down the breakdown of the stitches, leading to a longer absorption time. It is essential to keep wounds clean and follow proper wound care instructions to prevent infections and promote faster healing.
4. Individual Health Factors
Individual health factors, such as overall health, immune system function, and any underlying medical conditions, can also affect the absorption time of degradable stitches. Generally, individuals with healthy immune systems tend to have faster absorption rates compared to those with compromised immune systems. Additionally, certain medical conditions or medications may slow down the body’s healing process, resulting in a longer absorption time for the stitches.
It is important to note that the absorption time of degradable stitches can vary from person to person and case to case. While these factors can provide a general understanding of the factors that affect absorption time, it is always best to consult with a healthcare professional for personalized information and advice regarding your specific situation.
Caring for Degradable Stitches
When it comes to the healing process after a surgery or injury, caring for degradable stitches is crucial. While these stitches are designed to break down over time, it is important to properly care for them so that they can do their job effectively. Here are some tips to help you care for your degradable stitches:
1. Keep the Area Clean
One of the most important things you can do to care for your degradable stitches is to keep the area clean. This can help prevent infection and promote faster healing. Gently clean the area around the stitches with mild soap and water, and pat it dry with a clean towel. Avoid using harsh or scented soaps, as they can irritate the skin.
2. Avoid Disturbing the Stitches
While it may be tempting to scratch or pick at the stitches, it is important to avoid disturbing them. Scratching or picking at the stitches can cause them to come loose or delay the healing process. If you experience itching, try using a cold compress or applying an over-the-counter anti-itch cream to the area.
3. Watch for Signs of Infection
It is important to keep an eye out for signs of infection around the stitches. These signs may include increased redness, swelling, warmth, or pus coming from the wound. If you notice any of these symptoms, it is important to contact your doctor right away, as this may be a sign of an infection that needs to be treated.
