Most stitches are temporary and dissolve or are removed within days to weeks, but some types can remain permanently inside the body.
Understanding the Nature of Stitches
Stitches, also known as sutures, play a crucial role in wound care and healing. They bring together the edges of a cut or surgical incision, allowing the tissue to heal properly. But not all stitches are created equal. Some dissolve naturally over time, while others need to be removed manually. And then there are permanent stitches designed to stay inside the body indefinitely.
The question “Are Stitches Permanent?” often arises because people want to know what happens after their wound heals. The answer depends heavily on the type of stitch used and the purpose behind it.
Types of Stitches: Absorbable vs. Non-Absorbable
There are two main categories of stitches: absorbable (dissolvable) and non-absorbable (permanent).
- Absorbable stitches break down naturally inside the body over time, usually within days to months.
- Non-absorbable stitches are made from materials that do not degrade and may need removal or remain permanently under the skin.
Absorbable stitches are typically used for internal tissues or areas where stitch removal would be difficult or painful. Non-absorbable stitches are often preferred for skin closure or in surgeries requiring long-term wound support.
The Materials Behind Stitches
The composition of sutures influences whether they dissolve or stay put:
- Absorbable materials: Polyglycolic acid, polylactic acid, catgut (derived from sheep or cow intestines), and polydioxanone.
- Non-absorbable materials: Nylon, silk, polyester, polypropylene, stainless steel.
Each material has its own set of properties impacting strength, flexibility, and tissue reaction. For example, nylon is strong and causes minimal inflammation but requires removal after healing.
The Healing Timeline and Stitch Removal
How long stitches stay in place depends on several factors: wound location, depth, patient health, and type of suture used.
Skin Stitches: Temporary but Essential
Skin sutures usually last between 5 and 14 days before removal. Facial wounds might have stitches removed earlier (around 5 days) to reduce scarring risk. Areas under tension like joints may require longer stitch retention.
After this period, your healthcare provider will assess whether the wound has healed enough to safely remove the non-absorbable sutures. Leaving these stitches too long can cause complications like infection or scarring.
Dissolvable Stitches: The Silent Healers
Absorbable sutures begin breaking down soon after placement through hydrolysis or enzymatic digestion by the body’s cells. The timeline varies:
- Fast-dissolving sutures: Some start dissolving within a week.
- Slow-dissolving sutures: Others may last up to several months depending on material thickness and location.
These stitches don’t require removal visits but must be monitored for any signs of irritation or delayed healing.
The Role of Permanent Stitches in Surgery
Not all stitches are meant to vanish completely. Certain surgeries require permanent sutures to provide ongoing structural support inside the body.
When Are Permanent Stitches Used?
Permanent non-absorbable sutures anchor tissues that endure constant stress or movement such as:
- Heart valve repairs
- Tendon reattachments
- Hernia repairs with mesh reinforcement
- Surgical implants fixation
In these cases, removing the stitches is either impossible or unnecessary because they become integrated with surrounding tissue.
The Risks and Benefits of Permanent Sutures
Permanent sutures offer durability but carry potential risks:
- Benefits: Long-term strength prevents wound reopening; reduces need for repeat surgeries.
- Risks: Possible chronic irritation; foreign body reactions; risk of infection if exposed.
Surgeons weigh these pros and cons carefully before deciding on permanent suture use.
Suture Removal Process: What to Expect?
For those with non-absorbable external stitches, removal is a straightforward procedure performed by medical professionals.
The Procedure Explained
Typically scheduled within one to two weeks post-surgery or injury:
- The area is cleaned gently with antiseptic.
- A special stitch cutter or scissors trims each stitch close to skin.
- The suture is pulled out carefully without causing pain.
- A sterile dressing may be applied afterward.
Patients often feel minor discomfort but no significant pain during removal.
If You Miss Stitch Removal Appointments…
Leaving non-absorbable skin stitches in too long can lead to:
- Suture marks resembling tiny scars.
- Suture abscesses due to infection around trapped threads.
- Tissue embedding where skin grows over stitches making removal difficult.
If this happens accidentally, professional care is essential to avoid complications.
Dissolvable Stitch Breakdown: How Does It Work?
Absorbable sutures gradually lose strength as they hydrolyze—water molecules break down polymer chains—or enzymatic action digests natural fibers like catgut.
The Body’s Role in Dissolving Sutures
Cells called macrophages engulf suture fragments while enzymes accelerate degradation. This process varies widely based on:
- Suture material composition.
- Tissue environment (e.g., blood supply).
- The thickness and coating of the suture thread.
For example, polyglycolic acid dissolves faster than polydioxanone due to chemical structure differences.
The Timeline Table for Absorbable Sutures Breakdown Rates
| Suture Material | Dissolution Timeframe* | Main Use Cases |
|---|---|---|
| Catgut (natural) | 7–10 days (fast absorption) | Tissue repair in areas with rapid healing like mucosa |
| Polyglycolic Acid (synthetic) | 30–60 days (moderate absorption) | Tendon repair, subcutaneous tissue closure |
| Polydioxanone (synthetic) | 90–180 days (slow absorption) | Ligament repair, deep tissue support needing long-term strength |
| PGA Coated Vicryl (synthetic) | 56–70 days (moderate absorption) | Surgical wounds requiring intermediate support duration |
This table highlights why surgeons select specific suture types based on how fast they want them gone versus how much support they need during healing.
Caring for Your Stitches Properly Matters Most
Whether your stitches dissolve or need removal later on, proper care ensures smooth healing without infection or scarring issues.
Avoiding Infection Around Sutures
Follow these guidelines strictly:
- Keep the area clean and dry unless otherwise instructed by your doctor.
- Avoid touching your wound with dirty hands.
- If advised, apply antibiotic ointment sparingly around external stitches.
- Avoid soaking wounds in baths or swimming pools until fully healed.
Signs like redness spreading beyond the wound edge, swelling, pus discharge, increasing pain warrant urgent medical attention.
A Stitch-Friendly Diet & Lifestyle Tips for Healing Faster
Certain nutrients speed up tissue regeneration:
- Protein: Supports collagen production necessary for strong scars.
- Zinc & Vitamin C: Boost immune response aiding repair processes.
Also avoid smoking since it restricts blood flow delaying healing dramatically. Stay hydrated and get enough rest so your body can focus energy on recovery rather than other demands.
The Truth Behind “Are Stitches Permanent?” Revisited
So here’s what you really need to know about permanence:
Your answer isn’t one-size-fits-all. Most external skin stitches are temporary—they come out once your wound has closed securely. Absorbable internal sutures quietly vanish inside you over weeks or months without fuss. But some internal permanent sutures remain embedded indefinitely by design to hold tissues together under stress where removing them isn’t practical nor safe.
This means that while many people think all stitches disappear eventually—true for most cases—there’s a subset of surgical situations requiring permanent stitching material that stays put forever without causing harm when placed correctly by surgeons experienced in their use.

Frequently Asked Questions
Are Stitches Permanent or Temporary?
Most stitches are temporary and either dissolve naturally or are removed within days to weeks. However, some stitches are designed to be permanent and remain inside the body indefinitely, depending on the type and purpose of the suture used.
Are Stitches Permanent Inside the Body?
Permanent stitches, also known as non-absorbable sutures, can stay inside the body without dissolving. These are often used for long-term wound support or internal tissues where removal is difficult. Their materials do not degrade over time.
Are Stitches Permanent When Used on Skin?
Stitches placed on the skin are usually temporary and removed after healing, typically between 5 and 14 days. Leaving these stitches permanently can cause complications, so they are rarely intended to be permanent on skin wounds.
Are Stitches Permanent if Made from Absorbable Materials?
Absorbable stitches are not permanent; they break down naturally inside the body over days to months. These dissolvable sutures are commonly used for internal tissues or areas where stitch removal would be painful or impractical.
Are Stitches Permanent for All Types of Surgery?
The permanence of stitches depends on the surgery type and wound location. Some surgeries require permanent non-absorbable stitches for long-term support, while others use temporary absorbable sutures that dissolve as healing progresses.
Conclusion – Are Stitches Permanent?
In short: no—most are not permanent—but yes—some can be lifelong fixtures inside your body depending on medical necessity.
Understanding this distinction helps ease concerns about stitch removal timing and what happens beneath your skin after surgery.
Always follow your healthcare provider’s instructions regarding care and follow-up appointments.
