Dissolvable stitches break down naturally in the body within days to weeks, eliminating the need for removal.
The Science Behind Dissolvable Stitches
Sutures, or stitches, come in two main types: non-dissolvable and dissolvable. Dissolvable stitches, also called absorbable sutures, are designed to vanish on their own inside the body. They work by breaking down gradually through a natural chemical process called hydrolysis or enzymatic degradation. This means your body’s fluids and enzymes slowly digest the suture material over time.
The exact speed at which these stitches dissolve depends on the type of material used and where they’re placed. Some dissolve in just a few days, while others may take several weeks or even months. This slow breakdown helps support healing tissue until it’s strong enough to hold itself together.
Unlike traditional stitches that require a follow-up visit for removal, dissolvable stitches save you that extra trip to the doctor’s office. They’re especially handy for internal wounds or areas where stitch removal would be tricky or painful.
Types of Dissolvable Stitch Materials
Absorbable sutures come in various materials, each with unique characteristics affecting strength, absorption time, and tissue reaction. Here’s a quick overview of the most common types:
- Polyglycolic Acid (PGA): A synthetic polymer that dissolves within 60-90 days. PGA is strong initially but loses tensile strength quickly.
- Polylactic Acid (PLA): Another synthetic option that breaks down over 90-180 days, offering longer-lasting support.
- Polydioxanone (PDO): Known for its durability, PDO sutures can last up to six months before fully absorbing.
- Catgut: A natural suture made from animal intestines; it dissolves faster (7-14 days) but may cause more tissue reaction.
- Polyglactin (Vicryl): A popular synthetic choice that absorbs over 50-70 days with minimal tissue irritation.
Each material has its ideal uses depending on wound type and location. Surgeons select based on how long the wound needs support and how sensitive surrounding tissues are.
The Role of Hydrolysis and Enzymatic Breakdown
Dissolvable sutures degrade primarily through two processes:
- Hydrolysis: Water molecules enter the suture fibers and cleave chemical bonds, gradually weakening the thread until it disappears.
- Enzymatic Degradation: Body enzymes specifically target natural suture materials like catgut, breaking them down faster than synthetic types.
Synthetic sutures mostly rely on hydrolysis, which is slower but more predictable. Natural sutures dissolve quicker but might trigger minor inflammation due to their biological origin.
The Timeline: How Long Do Dissolvable Stitches Last?
Knowing when your stitches will dissolve helps you care for your wound properly and avoid complications. Here’s a general timeline to expect:
| Suture Material | Dissolution Timeframe | Typical Use Cases |
|---|---|---|
| Catgut | 7-14 days | Minor skin wounds, mucous membranes |
| Polyglycolic Acid (PGA) | 60-90 days | Tendon repair, internal organs |
| Polyglactin (Vicryl) | 50-70 days | Skin closure, subcutaneous tissue |
| Polydioxanone (PDO) | 180+ days | C-section incisions, fascia closure |
| Polylactic Acid (PLA) | 90-180 days | Surgical wounds needing longer support |
Keep in mind these timelines vary based on individual healing rates and the wound environment. For example, areas with high movement or moisture may cause faster degradation.
The Body’s Response During Dissolution
As stitches dissolve, your body treats them like tiny foreign objects at first but then gradually absorbs them without much fuss. Sometimes you might notice slight redness or mild swelling around the stitch site—this is normal inflammation signaling healing.
Occasionally, some people experience minor irritation or a small lump where sutures were placed; this usually resolves as the material breaks down completely.
If you see increasing redness, pus, severe pain, or other signs of infection near your stitches during this period, it’s important to get medical advice promptly.
Caring for Your Wound With Dissolvable Stitches
Proper care promotes smooth healing and ensures stitches dissolve as intended without complications. Here’s how to manage your wound after getting dissolvable stitches:
- Avoid soaking: Keep the wound dry during baths or showers for at least 24-48 hours unless otherwise directed.
- No picking: Resist scratching or pulling at stitches even if they itch as they start dissolving.
- Mild cleaning: Gently clean around the area with soap and water once cleared by your doctor.
- Avoid strenuous activity: Excess movement can stress healing tissue and delay stitch breakdown.
- No harsh chemicals: Steer clear of alcohol-based products or hydrogen peroxide near your wound—they can harm delicate skin cells.
- If advised: Apply antibiotic ointments sparingly if recommended by your healthcare provider.
Following these steps helps prevent infection and supports natural absorption of sutures without leaving scars or bumps behind.
Pain Management Around Dissolving Stitches
Mild discomfort is expected during healing but usually fades quickly. Over-the-counter pain relievers like acetaminophen or ibuprofen can ease soreness safely.
Avoid medications that thin blood unless prescribed since they might increase bleeding risk around fresh wounds.
If pain worsens suddenly or lasts beyond a week after surgery without improvement, reach out to your doctor for evaluation.

Frequently Asked Questions
How Do Stitches Dissolve Inside the Body?
Dissolvable stitches break down naturally through processes like hydrolysis and enzymatic degradation. Your body’s fluids and enzymes gradually digest the suture material, allowing the stitches to disappear without needing removal.
What Materials Are Used in Dissolvable Stitches?
Dissolvable stitches are made from materials such as polyglycolic acid, polylactic acid, polydioxanone, catgut, and polyglactin. Each type varies in how long it takes to dissolve and how it interacts with your tissues.
How Long Do Dissolvable Stitches Take to Dissolve?
The time for stitches to dissolve depends on their material and placement. Some dissolve in a few days, like catgut, while others, such as polydioxanone, can take several months to fully absorb.
Why Do Dissolvable Stitches Not Need Removal?
Dissolvable stitches eliminate the need for removal because they naturally break down inside your body. This is especially helpful for internal wounds or areas where removing stitches would be painful or difficult.
How Does Hydrolysis Affect the Dissolving of Stitches?
Hydrolysis is a chemical process where water molecules break down the suture fibers over time. This gradual weakening causes synthetic dissolvable stitches to disappear as part of the healing process.
The Advantages of Using Dissolvable Stitches Over Non-Dissolvable Ones
Dissolvable stitches offer several benefits that make them a preferred choice in many medical scenarios:
- No removal needed: Saves patients from extra appointments and discomfort associated with pulling out staples or threads.
- Lowers infection risk: Since there’s no external thread exposed after surgery to harbor bacteria.
- Smoother healing: Absorbable materials cause less scarring compared to some permanent sutures.Versatility: Suitable for internal tissues where removing stitches isn’t feasible.
However, non-dissolvable stitches still have their place when prolonged tensile strength is necessary beyond what absorbable options provide.
Dissolvable vs Non-Dissolvable: Key Differences Summarized
Feature Dissolvable Stitches Non-Dissolvable Stitches
Removal Required? No – naturally absorbed Yes – must be removed by doctor
Typical Use Cases Internal wounds; pediatric surgery; mucous membranes Skin closure; high-tension areas needing long-term support
Risk of Infection Lower – no external thread left behind Higher – external threads can harbor bacteria if not cared for properly
Healing Impact Less scarring; less tissue irritation (synthetic types) May cause more scarring due to removal process
Strength Duration Varies from days up to months depending on material Long-lasting strength until removed manually
The Process After Stitching: What Happens Inside Your Body?
Once dissolved stitches are placed in your skin or deeper tissues during surgery or injury repair, several things happen beneath the surface:
Your immune system kicks into gear immediately after injury by sending cells that clear debris and fight infection. The absorbable suture acts as temporary scaffolding holding edges together while new tissue forms across the gap.
This scaffold gradually weakens as hydrolysis breaks down polymers into smaller molecules easily absorbed by surrounding cells. Meanwhile, fibroblasts produce collagen fibers building fresh connective tissue matrix replacing damaged areas bit by bit.
This balancing act continues until your wound regains enough strength on its own—at which point stitch remnants have fully disappeared without leaving harmful residue behind.
Pitfalls That Can Delay Stitch Dissolution or Healing
Sometimes things don’t go as smoothly as planned with dissolvable stitches due to factors like:
- Poor blood supply reducing enzyme activity needed for absorption;
- Tight stitching causing restricted circulation;
- An infection triggering prolonged inflammation;
- Certain medications interfering with normal healing;
- Lifestyle factors such as smoking slowing tissue repair;
- The presence of foreign bodies causing granuloma formation instead of smooth absorption;
If you notice persistent lumps where stitches were placed weeks after surgery or unusual discharge around wounds despite proper care, consult your healthcare provider promptly to rule out complications requiring intervention.
Conclusion – How Do Stitches Dissolve?
Dissolvable stitches simplify wound care by naturally breaking down inside your body through hydrolysis and enzymatic action over days to months depending on their material type. They provide essential temporary support while minimizing discomfort from removal visits and lowering infection risks.
Understanding how these sutures work lets you better care for wounds post-procedure—keeping them clean and protected encourages smooth absorption without problems. Though most dissolve uneventfully within expected timelines shown here today, watch closely for signs of infection or delayed healing just in case.
In short: dissolvable stitches quietly do their job behind the scenes so you can focus on recovering comfortably without fussing over removing threads later on!
