Quick Answer: What is surgical mesh?
Surgical mesh is a screen-like medical device placed during hernia repair to reinforce weak or damaged muscle, usually in the belly or groin. Your own tissue grows into the mesh as you heal, making the repair stronger and lowering the chance the hernia comes back. Rare complications include infection, long-term pain, mesh breakage, rejection or erosion. [1]
What the research says
Mesh cuts the risk of a groin hernia coming back by about half. A review of 25 randomized trials (6,293 adults) found mesh repair lowered recurrence compared with stitches alone (risk ratio 0.46). In real terms, one recurrence was prevented for every 46 mesh repairs. Nerve, blood vessel and organ injuries were also less common with mesh, while fluid pockets (seromas) were somewhat more common. (Lockhart et al., Cochrane Database Syst Rev, 2018) [2]
For belly-wall and incisional hernias, mesh lowers recurrence by about 61%. A meta-analysis of 10 randomized trials (1,270 patients) found mesh repair reduced hernia recurrence compared with simple stitching (risk ratio 0.39). Overall complication rates were not significantly different between the two groups. (López-Cano et al., PLoS One, 2018) [3]
The benefit lasts for years. In a 10-year randomized trial of 181 patients with incisional hernias, the hernia came back in 63% of people repaired with stitches only, compared with 32% of those repaired with mesh. People in the mesh group also had less belly pain. (Burger et al., Ann Surg, 2004) [4]
Key takeaways
Surgical mesh reinforces the weak spot after a hernia is repaired.
Most mesh is synthetic. Polypropylene, a permanent plastic mesh, is the most common type.
Mesh can be permanent (non-absorbable) or temporary (absorbable).
It can sit on top of the muscle, between muscle layers, or beneath the muscle.
Most people return to work or school in about a week.
Call your doctor for severe pain, signs of infection, or new bowel problems.
What is surgical mesh?
Surgical mesh is a screen-like material that strengthens weakened or damaged tissue. It is used most often in the abdomen (belly) or groin. [1]
Most mesh is human-made (synthetic). Some types come from animal tissue. [1]
A surgeon places the mesh through a cut (incision). As your body heals, tissue grows into the tiny openings in the mesh. Think of how a tree grows into a chain-link fence, or how cement fills in around steel rebar. That ingrowth is what makes the repair strong. [1]
You may also hear it called hernia mesh or abdominal mesh.
How surgical mesh strengthens a hernia repair.
What is surgical mesh used for?
Surgical mesh is used to treat a hernia. A hernia happens when an organ or tissue pushes through a weak area in a muscle or tissue wall. [1] [6]
A surgeon can stitch a weak area closed. But over time, normal wear and tear can pull those stitches apart again. Mesh adds support so the muscle stays together. [1]
Common hernias treated with surgery include inguinal hernia, femoral hernia and umbilical hernia. [1]
What is surgical mesh made of?
Surgical mesh is made from either synthetic polymers or biopolymers. [1]
Synthetic polymers are human-made materials that come from petroleum oil.
Biopolymers come from the cells of living organisms.
Mesh type | Material examples | Key point |
Non-absorbable synthetic | Polypropylene | Most common type; permanent support |
Absorbable synthetic | Polyglycolic acid, polycaprolactone | Temporary; the body slowly replaces it with new tissue |
Biologic | Acellular collagen from cows or pigs | Comes from animal tissue |
Composite | A combination of the other materials | Mixes two or more mesh materials |
[1] [5]
Knitted vs. woven mesh
Mesh also comes in two forms, based on how its threads are made. [1]
Form | What it looks like | How it behaves |
Knitted | One long thread looping around itself, like a knit sweater | More flexible and porous; lets a lot of tissue grow in |
Woven | Threads crossing over and under each other, like a chessboard | More consistent strength; each square handles stretch and pressure the same way |

Surgical mesh materials and forms.
How long does surgical mesh last?
How long surgical mesh lasts depends on the type: non-absorbable mesh is permanent, while absorbable mesh is slowly replaced by your own tissue. [1]
Non-absorbable mesh is permanent. It strengthens and reinforces the muscle or tissue for good. [1]
Absorbable mesh is not permanent. Your body slowly takes it in and replaces it with new tissue or muscle over time. [1]
Each type has pros and cons. Your surgeon will explain which one fits your situation and answer your questions. [1]
How is surgical mesh placed?
Surgical mesh is placed during hernia repair surgery, after the surgeon moves the bulging tissue back and stitches the weak muscle closed. The steps depend on the type of hernia repair surgery you need. In general, the surgeon will: [1]
Make the incision. Open surgery uses one cut several inches long. Laparoscopic or robotic surgery uses several smaller cuts.
Fix the hernia. The bulging tissue is moved back into place, and the weak muscle is stitched closed.
Add the mesh. The mesh is placed below, between, or on top of the muscle to strengthen the repair.
Close the incision. The cut or cuts are closed with stitches.
Where is surgical mesh placed?
Placement depends on where the hernia is and how severe it is. [1]
Position | Where the mesh sits |
On top of the muscle | On the outside of the abdominal wall |
Between muscle layers | Between the layers of muscle in the abdominal wall |
Beneath the muscle | Between the intestines and the abdominal wall |
[1]
Your surgeon will explain where your mesh will go during your consultation before surgery. [1]

What are the benefits of surgical mesh?
The main benefit of surgical mesh is that it is a safe, effective and common hernia treatment. [1]
It also makes it less likely that the hernia will come back after surgery. [1] [2] [3]
What are the risks of surgical mesh?
The risks of surgical mesh are low, but like any operation, there are possible downsides. [1]
Mesh-related risks:
Infection
Non-absorbable synthetic mesh can break, letting the muscles separate again (the hernia comes back)
Rarely, mesh placed near organs can wear into (erode into) the intestines or bladder
The mesh may not grow into the muscle tissue as expected
Rejection of the mesh, which is rare
General surgery risks:
Problems with anesthesia
Too much bleeding
Long-term numbness or pain in the area, possibly from nerve damage
[1] [5]
Why surgeons still recommend mesh
You and your care team will weigh the risks of surgery against the risks of not having surgery, or not using mesh. [1]
In most cases, a surgeon uses mesh when skipping it would put you at greater risk. An untreated hernia can lead to: [1]
Bowel obstruction (a blockage)
Bowel strangulation (the blood supply to the bowel is cut off)
Emergency surgery
That said, most people choose hernia repair because the hernia causes pain and limits their daily life. [1]
How long is recovery after surgical mesh hernia repair?
Most people return to work or school about a week after surgical mesh hernia repair, with high-impact activity after a few months. Recovery depends on the type and size of your hernia and the surgery you have. [1]
Time after surgery | What you can usually do |
Day 1 | Light walking, as much as you can comfortably manage |
About 1 week | Return to work or school |
At least 2 weeks | Running, cycling or swimming |
A few months | High-impact activity such as sprinting, sports or weightlifting |
[1]
You may need more time off if your job is physically demanding or your hernia was large. Your surgeon will give you a plan. [1]
Tips to make recovery easier
Avoid straining when using the bathroom.
Drink plenty of fluids, especially water.
Take pain medicine exactly as your care team prescribed.
Walk every day. It improves blood flow and makes it easier to pee and poop.

When should you call your doctor after surgical mesh surgery?
Call your healthcare provider after surgical mesh surgery if you have: [1]
Severe pain
Signs of infection, such as skin discoloration around the incision (red, purple, brown or black), fever, or yellow drainage from the incision
New bowel problems, such as constipation, diarrhea, gas or bloating
Conclusion
Feeling nervous before hernia surgery is normal. Surgical mesh is a common and effective device that lowers the chance your hernia comes back. Serious complications are rare, and most people are back to their normal routine within about a week, with full activity in a few months.
Your surgeon will review your options, recommend the right mesh and placement for you, and explain what to expect during recovery.

FAQ
Is surgical mesh safe?
Yes, for most people. Mesh repair is a safe, effective and common hernia treatment. Complications are rare but can include infection, long-term pain, rejection, or erosion into nearby organs.
What is hernia mesh made of?
Most hernia mesh is synthetic, and polypropylene is the most common material. Other options include absorbable synthetic mesh, biologic mesh made from cow or pig collagen, and composite mesh that combines materials.
Is surgical mesh permanent?
Non-absorbable mesh is permanent and gives lasting support. Absorbable mesh is temporary; the body slowly absorbs it and replaces it with new tissue.
Can a hernia come back after mesh repair?
It can, but mesh makes this less likely. In some cases, permanent synthetic mesh can break and allow the muscle to separate again.
Can my body reject surgical mesh?
Rejection is possible but rare. Tell your doctor right away if you have severe pain or signs of infection after surgery.
Where is hernia mesh placed?
It can be placed on top of the abdominal muscle, between muscle layers, or beneath the muscle between the intestines and the abdominal wall. The spot depends on where the hernia is and how severe it is.
How long does it take to recover from hernia mesh surgery?
Most people go back to work or school after about a week. You can walk the day after surgery, wait at least two weeks for running, cycling or swimming, and wait a few months for heavy lifting or sports.
Is mesh always used to repair a hernia?
No. A surgeon can stitch a hernia closed without mesh. Mesh is usually added when the risk of not using it is greater, because stitched tissue can slowly pull apart over time.
What symptoms after mesh surgery need a doctor?
Severe pain, fever, discolored skin around the incision, yellow drainage, or new bowel problems such as constipation, diarrhea, gas or bloating.
What pain is normal after mesh hernia repair?
Soreness, swelling and bruising around the incision are common in the first days to weeks and should slowly improve. Pain that is severe, getting worse or lasting for months should be checked by your surgeon.
