Hernia

Hernia - inguinal; Inguinal hernia; Direct and indirect hernia; Rupture; Strangulation; Incarceration

Usually, there is no clear cause of a hernia. Sometimes, hernias occur with:

• Heavy lifting
• Straining while using the toilet
• Any activity that raises the pressure inside the belly

Hernias may be present at birth, but the bulge may not be noticeable until later in life. Some people have a family history of hernias.

Babies and children can get hernias. It happens when there is weakness in the belly wall. Inguinal hernias are common in boys. Some children do not have symptoms until they are adults.

Any activity or medical problem that increases pressure on the tissue in the belly wall and muscles may lead to a hernia, including:

• Chronic constipation and pushing hard (straining) to have a bowel movement
• Chronic cough
• Cystic fibrosis
• Enlarged prostate, straining to urinate
• Extra weight
• Fluid in the abdomen (ascites)
• Heavy lifting
• Peritoneal dialysis
• Poor nutrition
• Smoking
• Overexertion
• Undescended testicles

There are usually no symptoms. Some people have discomfort or pain. The discomfort may be worse when standing, straining, or lifting heavy objects. In time, the most common complaint is a bump that is sore and growing.

When a hernia gets bigger, it may get stuck inside the hole and lose its blood supply. This is called strangulation. Symptoms include:

• Nausea and vomiting
• Not being able to pass gas or have bowel movements

When this occurs, surgery is needed right away.

The health care provider can usually see or feel a hernia when you are examined. You may be asked to cough, bend, push, or lift. The hernia may get bigger when you do this.

The hernia (bulge) may not be easily seen in infants and children, except when the child is crying or coughing.

Ultrasound or CT scan may be done to look for a hernia.

If there is a blockage in the bowel, an x-ray of the abdomen will likely be done.

Surgery is the only treatment that can permanently fix a hernia. Surgery may be more risky for people with serious medical problems.

Surgery repairs the weakened abdominal wall tissue (fascia) and closes any holes. Most hernias are closed with stitches and sometimes with mesh patches to plug the hole.

An umbilical hernia that does not heal on its own by the time a child is 5 years old will likely be repaired.

The outcome for most hernias is usually good with treatment. It is rare for a hernia to come back. Incisional hernias are more likely to return.

In rare cases, inguinal hernia repair can damage structures involved in the function of a man's testicles.

Another risk of hernia surgery is nerve damage, which can lead to numbness in the groin area.

If a part of the bowel was trapped or strangulated before surgery, bowel perforation or dead bowel may result.

Call your health care provider right away if:

• You have a painful hernia and the contents cannot be pushed back into the abdomen using gentle pressure
• You develop nausea, vomiting, or a fever along with a painful hernia
• You have a hernia that becomes red, purple, dark, or discolored

Call your provider if:

• You have groin pain, swelling, or a bulge
• You have a bulge or swelling in the groin or belly button, or that is associated with a previous surgical cut.

To prevent a hernia:

• Use proper lifting techniques.
• Lose weight if you are overweight.
• Relieve or avoid constipation by eating plenty of fiber, drinking lots of fluid, going to the bathroom as soon as you have the urge, and exercising regularly.
• Men should see their health care provider if they strain with urination. This may be a symptom of an enlarged prostate.
