Umbilical Hernia
An umbilical hernia happens when part of the intestine or fat bulges through a weak spot near the navel. This creates a visible bulge or swelling around the belly button. It can affect anyone, but is more common in babies and young kids.
Some umbilical hernias heal on their own, but others might need medical help or surgery. Knowing the causes, symptoms, and treatment options is key for those dealing with this issue or caring for someone with an abdominal bulge near the navel.
We will dive into umbilical hernias, covering their causes, symptoms, and how to manage them. This includes diagnostic and treatment methods to help manage this condition effectively.
What is an Umbilical Hernia?
An umbilical hernia is a common abdominal wall defect. It happens when part of the intestine or fat bulges through a weak spot near the navel. This weakness is often there from birth, but can also appear later.
The umbilical ring is a hole in the abdominal muscles for the umbilical cord. It usually closes after birth. But sometimes, it doesn’t close fully, leaving a weak spot. This spot can bulge when the belly gets tight.
Umbilical hernias are common in babies but can also happen in adults. Factors that increase the risk of getting a hernia include:
| Risk Factor | Description |
|---|---|
| Premature birth | Infants born early have weaker belly muscles |
| Low birth weight | Babies who are born too small are more likely to get hernias |
| Obesity | Being overweight adds extra pressure on the belly |
| Multiple pregnancies | Women who have had many babies are at higher risk |
| Chronic cough | Long-term coughing can weaken the belly muscles |
Most umbilical hernias are not serious but can be uncomfortable. They might need treatment if they don’t get better by themselves. In rare cases, a hernia can cut off blood to the bulging tissue, which is a medical emergency.
Causes of Umbilical Hernias
Umbilical hernias can happen for many reasons. Congenital defects and increased abdominal pressure are the top causes. Knowing these risk factors helps prevent and manage umbilical hernias well.
Congenital Factors
Congenital umbilical hernias happen when the muscles around the belly button don’t close fully in the womb. This creates a weak spot where the intestines or other tissues can bulge out. Some risk factors for congenital umbilical hernias include:
| Risk Factor | Description |
|---|---|
| Premature birth | Babies born before 37 weeks of gestation have a higher risk of developing umbilical hernias |
| Low birth weight | Infants weighing less than 5.5 pounds at birth are more prone to umbilical hernias |
| Family history | Having a family member with an umbilical hernia increases the likelihood of developing one |
Increased Abdominal Pressure
In adults, umbilical hernias often come from increased abdominal pressure. This pressure can weaken the muscles and push the intestines through the belly button. Some common causes of increased abdominal pressure include:
- Obesity or sudden weight gain
- Multiple pregnancies
- Chronic coughing or straining during bowel movements
- Lifting heavy objects
- Fluid accumulation in the abdominal cavity (ascites)
By keeping a healthy weight, lifting properly, and managing chronic conditions, people can lower their risk of getting an umbilical hernia.
Symptoms of Umbilical Hernias
It’s important to know the signs of an umbilical hernia to get help quickly. A visible bulge near the navel is a common sign. This bulge can grow when you cough, strain, or cry, like babies do.
Small hernias might not hurt much. But big ones can cause pain and discomfort in your belly.
Visible Bulge Near the Navel
A bulge near the belly button is a clear sign of an umbilical hernia. The size of the bulge can change, getting bigger with pressure. This can happen when you cry, cough, or strain.
Some bulges can go back into your belly when you relax or lie down. This is called reducible.
Pain and Discomfort
Small hernias might not hurt, but big ones can. The pain can get worse with activity or when your belly is pressed. You might feel a pulling or aching near your navel.
Complications
Umbilical hernias can sometimes cause serious problems. Incarceration happens when the hernia gets stuck, causing a lot of pain. It can also cut off blood to the trapped tissue.
Strangulation is a serious emergency. It happens when the stuck hernia loses blood, causing tissue death. Signs include:
| Complication | Symptoms |
|---|---|
| Incarceration | Severe pain, swelling, redness, unable to push the hernia back |
| Strangulation | Intense pain, nausea, vomiting, fever, fast heart rate |
If you think you have an incarcerated or strangulated hernia, get medical help right away. This can prevent more harm and damage.
Diagnosing Umbilical Hernias
Getting a correct hernia diagnosis is key to finding the right treatment. The first step is usually a physical examination by a doctor. They will look and feel around the navel to see if there’s a hernia, how big it is, and if it can be pushed back in.
At times, more imaging tests are needed to be sure of the diagnosis or to see how serious the hernia is. These tests give a clearer picture of the hernia and the abdominal wall. Common tests include:
| Imaging Test | Description |
|---|---|
| Ultrasound | A non-invasive test that uses sound waves to show images of the abdominal wall and hernia. It’s often the first choice, mainly for kids and babies. |
| CT Scan | A CT scan combines X-rays and computer tech to show detailed images of the abdomen. It helps see the size and what’s inside the hernia sac, and spots any problems. |
| MRI | MRI uses magnets and radio waves to create detailed images of the abdominal wall and tissues. Though not often used for umbilical hernias, an MRI might be ordered if other tests don’t give clear results. |
Doctors use the results from the physical exam and imaging tests to accurately diagnose umbilical hernias. They then create a treatment plan that fits the patient’s age, hernia size, symptoms, and health.
Treatment Options for Umbilical Hernias
There are two main ways to treat umbilical hernias: watchful waiting and surgery. The right choice depends on the hernia’s size, symptoms, and the patient’s health.
For infants and young children, some hernias might heal without treatment. This is called watchful waiting. Doctors keep an eye on the hernia to make sure it doesn’t get worse. If it does, surgery might be needed.
Watchful Waiting
Watchful waiting is often the first step for small hernias in kids. Many of these hernias close on their own by age 4 or 5. Parents and doctors watch the hernia closely to see if it gets better or worse.
If the hernia gets bigger, hurts, or doesn’t close by age 4-5, surgery is usually recommended. Adults with umbilical hernias usually need surgery too, because they don’t often close on their own.
Surgical Repair
Surgery is needed for hernias that don’t get better or cause problems. The surgery aims to put the tissue back in place and strengthen the belly wall. There are two main types: open repair and laparoscopic repair.
Open repair makes a cut near the belly button to fix the hernia. Laparoscopic repair uses small cuts and a camera to do the same thing. Both methods try to fix the hernia well and prevent it from coming back.
Choosing between open and laparoscopic repair depends on the hernia’s size, the patient’s health, and the surgeon’s skill. Sometimes, a mesh is used to help the repair last longer, which is more common in bigger hernias or those that have come back.
Laparoscopic Umbilical Hernia Repair
Laparoscopic surgery is a minimally invasive way to fix umbilical hernias. It uses small cuts near the belly button. A thin, lighted scope and special tools are inserted through these cuts.
Surgeons use advanced technology to repair the hernia with great care. This method causes less damage to the surrounding tissues.
Benefits of Laparoscopic Surgery
Laparoscopic umbilical hernia repair has many benefits. It’s better than traditional open surgery in many ways. Patients usually get:
- Less pain and discomfort after surgery
- Smaller scars that are less visible
- Shorter hospital stays, often going home the same day
- Quicker recovery times, getting back to normal activities faster
- Lower risk of complications like infection and bleeding
Procedure Overview
The patient is under general anesthesia during the surgery. The surgeon makes a few small cuts near the navel. A laparoscope, a thin tube with a light and camera, is inserted.
This lets the surgeon see the hernia and the tissues around it on a monitor. The surgeon then uses special tools to move the bulging tissue back inside the belly.
To make sure the hernia doesn’t come back, a mesh patch might be used. The mesh is held in place with sutures or tacks. This gives extra support to the weak spot in the belly wall.
After the repair, the cuts are closed with sutures or glue. A sterile dressing is put on. Patients stay in a recovery room until they’re awake and alert. Most can go home the same day to start their recovery.
Open Umbilical Hernia Repair
Laparoscopic surgery is common for umbilical hernias, but open surgery is also used. This method involves a bigger surgical incision near the belly button. It’s used to fix the hernia.
In open surgery, the surgeon separates the hernia sac from the tissues. They then push the bulging tissue back into the belly. To keep the wall strong, they might sew the muscles together or use a mesh patch.
Open surgery needs a longer cut than laparoscopic methods. This can lead to more pain and a longer healing time. But, it’s better for big hernias, complex cases, or when laparoscopy isn’t safe.
After open surgery, patients might feel pain and swelling. Pain meds and ice packs can help. Most can start light activities in a few days. But, they should avoid heavy lifting for weeks. Following the surgeon’s advice is key for a good recovery.
Mesh Repair for Umbilical Hernias
Many patients with umbilical hernias get a surgical mesh to strengthen their abdominal wall. This helps prevent the hernia from coming back. Mesh repair is popular because it works well in keeping the hernia site strong.
Types of Mesh Materials
There are different types of surgical mesh for umbilical hernia repair. These include:
- Polypropylene: A synthetic, non-absorbable mesh that is durable and flexible.
- Polyester: Another synthetic, non-absorbable mesh known for its strength and biocompatibility.
- Biological mesh: Made from animal tissue, this mesh is absorbable and can be used in contaminated or infected surgical fields.
The type of mesh used depends on the hernia size, the patient’s health, and the surgeon’s choice.
Advantages of Mesh Repair
Mesh repair in umbilical hernia surgery has many benefits. These include:
- Lower risk of hernia recurrence compared to suture repair alone
- Increased strength and support for the abdominal wall
- Faster recovery times and less postoperative pain
- Improved long-term outcomes and patient satisfaction
Studies show mesh repair greatly lowers hernia recurrence risk. This is true for larger hernias and in patients with obesity or chronic cough. Surgical mesh ensures a strong repair, leading to better long-term results and patient happiness.

Pediatric Umbilical Hernias
Umbilical hernias are common in infants and young children. They happen when part of the intestine bulges through a weak spot near the belly button. It’s good to know how common they are and what treatment options are available.
Prevalence in Infants
About 20% of newborns have umbilical hernias. They are more common in premature babies and those with low birth weight. Usually, these hernias close on their own as the child grows and the muscles get stronger. This often happens by the time the child is 2 or 3 years old.
Treatment Considerations for Children
Most children with umbilical hernias need only to be watched by a pediatrician. If the hernia is small and doesn’t hurt, surgery might not be needed. But if it’s big, hurts, or doesn’t close by age 4 or 5, surgery might be suggested. This is to avoid serious problems like intestine strangulation. The choice to have surgery depends on the child’s specific situation and will be decided with a pediatric surgeon.
