The Two Main Types of Stitches
Sutures are primarily classified into two types: absorbable (dissolvable) and non-absorbable (permanent). The key difference lies in the material and their purpose. Knowing which type you have is the first step to understanding what to expect during your recovery.
Dissolvable vs. Non-Dissolvable Stitches
Dissolvable stitches are made from materials that your body's enzymes or water can naturally break down. These are often used for internal closures, such as after abdominal surgery, or for deep layers of a wound, to eliminate the need for a second procedure to remove them. You might see small pieces of the knot or suture material come to the surface and fall off as the wound heals, which is a normal part of the process.
Non-dissolvable stitches are made from strong materials like nylon, silk, or polypropylene. They are meant to remain intact and are used for closing external wounds, especially in areas with high tension. A healthcare provider must remove these stitches once the wound has healed sufficiently, usually within one to three weeks, depending on the location. Attempting to remove them yourself can lead to infection or reopening the wound.
The Natural Process of Stitches Falling Out
For those with dissolvable sutures, the process of them falling out is part of your body's natural healing. As the wound closes and new tissue forms, the sutures gradually lose their purpose and begin to break down. The timeline for this can vary significantly based on the material used, the size of the wound, and its location. Some dissolve within a week or two, while others can take several months. Your doctor or surgeon will provide a timeline for what you can expect.
Factors Influencing Dissolving Time
- Material: Different absorbable materials have different degradation rates. For example, some synthetic materials take longer to break down than natural ones like chromic gut.
- Location: Wounds in areas with good blood flow, like the mouth, tend to dissolve faster than those in areas with less circulation.
- Individual Healing: Every person's body and healing process is unique, which can affect the speed at which stitches dissolve.
What if My Stitches Fall Out Prematurely?
Stitches coming out before the wound is fully healed can be a cause for concern. This can happen due to several reasons, including excessive movement, a high-tension area, or an infection. If you notice your stitches have fallen out and the wound has opened or is gaping, you should contact your doctor immediately. This is particularly critical for facial wounds or cuts on a child, which may need to be re-stitched or secured with medical tape within 48 hours for optimal healing and appearance.
Signs of a Problem
It's important to monitor your wound for signs that something is wrong. While some shedding of dissolvable sutures is normal, these symptoms may indicate an issue:
- Wound Reopening: The most obvious sign of a problem is the wound edges separating.
- Infection: Watch for signs like increased redness, swelling, warmth around the wound, pus, or fever.
- Excessive Bleeding: While some light bleeding is normal, persistent or heavy bleeding requires medical attention.
- Significant Pain: Increasing or severe pain is not a typical sign of healthy healing.
Comparison of Absorbable and Non-Absorbable Stitches
| Feature | Absorbable (Dissolvable) Stitches | Non-Absorbable (Permanent) Stitches |
|---|---|---|
| Material | Natural (e.g., chromic gut) or synthetic (e.g., Vicryl, Dexon) | Synthetic (e.g., nylon, polypropylene) or natural (e.g., silk) |
| Purpose | Internal procedures, deep tissue repair, hard-to-reach wounds | External skin closures, high-tension areas (joints), long-term support |
| Removal | Not required; dissolves naturally in the body over time | Must be removed by a healthcare professional |
| Appearance | Often clear, white, or light in color; may become slimy or crusty as they break down | Can be various colors (blue, black) and appear like a fine, taut thread |
| Duration | Weeks to months, depending on the material and location | Typically removed after 1-3 weeks, though some may remain longer |
Proper Care for Your Wound and Stitches
Whether your stitches are designed to fall out or need to be removed, proper wound care is essential for a smooth recovery and minimal scarring. Always follow your doctor's specific instructions. General guidelines include:
- Keep the area clean: Gently wash the wound as instructed, but avoid vigorous scrubbing. Pat the area dry with a clean towel.
- Keep it dry: Avoid soaking the wound in baths or swimming pools, especially in the first few days. Gentle showering is often allowed after 48 hours, but confirm with your doctor.
- Avoid picking: It can be tempting to scratch or pick at crusty stitches, but this can introduce bacteria and disrupt the healing process.
- Protect the wound: Avoid activities that put strain or tension on the area. This is a common cause of premature stitch removal or wound dehiscence.
- Watch for infection: Be vigilant for signs of infection and contact your doctor if you have concerns.

Conclusion
While the sight of a stitch falling out can be alarming, it is often a normal sign of healing if you have dissolvable sutures. However, it is crucial to confirm the type of stitches you have with your healthcare provider and to monitor your wound for signs of premature loosening or infection. Knowing whether your stitches are designed to dissolve or require professional removal is the most important step in ensuring a healthy and complication-free recovery. Always follow your doctor's advice and contact them immediately if you notice concerning symptoms.
