How to Recognize a Hernia

Every organ in the human body is situated in a hollow space referred to as a 'cavity.' A hernia occurs when an organ protrudes beyond its natural cavity. Typically, this condition isn't life-threatening and can sometimes resolve on its own. Hernias are most commonly found in the abdominal region (any area between the chest and the hips), with 75%-80% of cases occurring in the groin. The risk of a hernia increases with age, and the risks associated with surgery also rise as you get older. There are various types of hernias, each requiring a specific treatment method, making it essential to equip oneself with the right knowledge.

Assessing Risk Factors. A hernia can affect anyone, but certain factors increase the risk of developing one. These factors often involve chronic conditions or those that progress over time – for instance, severe coughing. Risk factors for hernias include:

• Increased abdominal pressure
• Coughing
• Lifting heavy objects
• Constipation
• Pregnancy
• Obesity
• Older age
• Smoking
• Use of steroids

Notice the bulges on the body. A hernia is a defect in the muscles that contain organs. Due to this defect, an organ is pushed outside, causing a hernia. When the organ protrudes, it creates a swollen area or bulge on the skin. The hernia bulge tends to increase in size when you stand or strain. The location of the bulge depends on the type of hernia. The terms used for different hernia types also indicate their location or cause.

• Inguinal hernia – Occurs in the groin (between the hip bone and the perineum) or in the inguinal region.
• Umbilical hernia – Occurs around the belly button.
• Femoral hernia – Occurs along the inner thigh.
• Incisional hernia – Occurs when a previous surgical incision creates weak spots in the muscles containing organs.
• Diaphragmatic hernia or hiatal hernia – Occurs due to a congenital defect in the diaphragm.

Be aware of vomiting. If the hernia affects the intestines, it can alter or even block the flow of food through the digestive system. This can lead to bloating and cause nausea and vomiting. If the intestines are not completely obstructed, the symptoms may be milder, such as nausea without vomiting or a loss of appetite.

Watch for constipation. Constipation can occur with an inguinal hernia or femoral hernia. Essentially, constipation is the opposite of vomiting. You may experience constipation when the waste material is blocked – it stays inside instead of being expelled. Naturally, this symptom requires immediate surgical intervention.

• A hernia can be very serious if it interferes with bodily functions essential for survival. You should promptly seek medical attention if you experience constipation.

Don’t ignore abnormal fullness. Many people with a hernia don’t experience pain or severe, obvious symptoms. However, they may feel a heaviness or fullness in the affected area, especially in the abdomen. You might attribute this to bloating. If nothing else, you’ll notice a feeling of fullness, weakness, or vague pressure in the abdominal area. This ‘bloating’ sensation may subside when you rest in a reclining position.

Monitor the pain level. Although not always present, pain is a sign of a hernia, particularly when complications arise. Inflammation may cause a burning or sharp pain. Accumulating pressure can lead to severe pain, a symptom indicating that the hernia has come into contact with the muscle wall. Pain associated with a hernia may vary at different stages:

• Irreducible hernia: The hernia cannot return to its normal position and keeps enlarging; occasional pain may be felt.
• Strangulated hernia: The organ loses its blood supply and may die rapidly if not treated. You will experience significant pain, along with nausea, vomiting, fever, and difficulty passing stool. This case requires emergency surgery.
• Hiatal hernia: The stomach bulges through the diaphragm, causing chest pain. This condition also disrupts the food flow, leading to acid reflux and difficulty swallowing.
• Untreated hernia: The hernia is usually painless and asymptomatic, but if left untreated, it can cause pain and other health issues.

Know when to see a doctor. Every hernia case has the potential to become dangerous. If you suspect that you have a hernia, it is crucial to get checked as soon as possible. A doctor will assess whether you have a hernia and discuss the severity and available treatment options.

• If you know you have a hernia and experience sudden pain at the site, you should go to the emergency room immediately. The hernia may become ‘strangulated,’ cutting off its blood supply, which is very dangerous.

Consider gender factors. Men are more likely to develop hernias than women. Several studies show that even congenital hernias, which are common in newborns, predominantly occur in boys. This trend continues into adulthood. The higher risk of hernias in men may be linked to undescended testicles. Normally, in boys, the testicles descend into the scrotum via the inguinal canal before birth. The inguinal canal, which contains ligaments connected to the testicles, usually closes after birth. However, in some cases, the inguinal canal does not close properly, increasing the risk of a hernia.

Consider family history. If someone in your family has a history of hernias, you are more likely to develop one yourself. Some genetic disorders affect muscles and connective tissues, making you more prone to hernias. Keep in mind that this genetic link only applies to congenital defects. Overall, the exact hereditary pattern of hernias is still unclear.

• If you have a personal history of hernias, your future risk of developing one will be higher.

Consider lung conditions. Cystic fibrosis (a life-threatening lung disease) causes thick mucus to build up in the lungs. Patients often experience chronic coughing as their bodies attempt to expel the mucus. The increased pressure from coughing is a risk factor for hernias. This type of coughing exerts significant pressure on the lungs, which can damage the muscle walls. Patients will feel pain and discomfort when coughing.

• Smokers are also at a higher risk of developing chronic coughs and are more likely to experience hernias.

Pay attention to chronic constipation. Constipation forces you to strain your abdominal muscles when having a bowel movement. If your abdominal muscles are weak and frequently under pressure, you are at a higher risk of developing a hernia.

• Muscle weakness often results from poor nutrition, lack of exercise, and aging.
• Straining while urinating can also increase your risk of a hernia.

Understand that you are at risk of hernias during pregnancy. As the fetus grows in the womb, it creates increasing pressure within the abdomen. The growing belly weight is another contributing factor to the development of hernias.

• Premature infants also face a risk of hernias because their muscles and tissues are not fully developed and firm.
• Congenital genital defects in newborns may also increase the risk of hernias. These defects can include abnormal urethra placement, fluid retention in the testicles, and ambiguous genitalia (having characteristics of both sexes).

Strive to maintain a healthy weight. Obese and overweight individuals are generally at a higher risk of developing a hernia. Just like pregnant women, a larger belly increases the pressure in the abdomen, affecting weak muscles. If you are overweight, it’s best to start planning a weight loss strategy now.

• Be aware that rapid weight loss through extreme dieting can also weaken muscles and lead to hernias. If you lose weight, make sure to do so gradually and healthily.

Consider whether your occupation could be the culprit. You are at a higher risk of a hernia if your job requires prolonged standing and heavy lifting. Certain professions are more prone to hernias, including construction workers, salespeople, carpenters, and more. If you work in such a job, consider discussing with your employer. You might be able to arrange a position that reduces the risk of hernias.

Understand how doctors diagnose a hernia. During a physical exam, the doctor will ask you to stand up. As the doctor examines the swollen area, you will be instructed to cough, tense your muscles, or move as best as you can. The doctor will assess the flexibility and movement at the suspected hernia site. After this evaluation, the doctor will be able to diagnose whether you have a hernia and determine its type.

Recognize the inguinal hernia type. This is the most common type of hernia, occurring when the intestines or bladder push through the lower abdominal wall into the groin and inguinal canal. In men, the inguinal canal contains ligaments attached to the testes, and hernias often occur due to natural weakness within the canal. In women, the inguinal canal contains ligaments that secure the uterus in place. There are two types of inguinal hernias: direct and the more common indirect hernia.

• Direct inguinal hernia: Place your finger on the inguinal canal – the fold along the pelvis where the legs meet. You will feel a bulging mass pushing toward the front of the body; this mass will enlarge when you cough.
• Indirect inguinal hernia: When pressing on the inguinal canal, you will notice a bulge that appears from the outside, pushing inward (from the side toward the center). This mass may also shift toward the scrotum.

Suspect a hiatal hernia in individuals over 50 years old. A hiatal hernia occurs when the upper part of the stomach pushes through a gap in the diaphragm into the chest cavity. However, this type of hernia typically affects individuals over 50. If a child develops a hiatal hernia, it is likely a congenital defect.

• The diaphragm is a thin muscle that facilitates breathing. It is also responsible for separating the organs in the abdomen from those in the chest.
• This type of hernia can cause a burning sensation in the stomach, chest pain, and difficulty swallowing.

Observe for an umbilical hernia in newborns. Although an umbilical hernia can develop later, it is most commonly seen in newborns and infants under 6 months old. This condition occurs when part of the intestines pushes through the abdominal wall around the belly button. The bulge will become more noticeable when the baby cries.

• In an umbilical hernia, you will see a bulge around the belly button area.
• Umbilical hernias often resolve on their own. However, if the bulge persists until the child is 5 to 6 years old, is large, or causes symptoms, surgery may be required.
• Note the size; a small bulge of about 1.25 cm may disappear on its own. A larger bulge will require surgery.

Be cautious with incisional hernias after surgery. Surgical wounds require time to heal and for the surrounding muscles to regain strength. An incisional hernia occurs when the organs push through the surgical incision before it has properly healed. This condition is more common in older adults and those who are overweight.

• Gently but firmly press your fingers near the incision site. You may feel a bulging mass in the area.

Identify femoral hernias in women. Although femoral hernias can affect both sexes, they are more common in women due to their typically wider pelvis. The pelvis contains a canal through which arteries, veins, and nerves pass to the upper thigh. This canal is usually narrow, but it tends to widen during pregnancy or in cases of obesity. When the canal expands, it becomes weaker and more susceptible to hernias.

Notify your doctor immediately if acute pain occurs. When hernia symptoms appear suddenly, the first thing your doctor will do is control your pain. In the case of a strangulated hernia, the doctor may first attempt to push the hernia back into its original position. This can reduce acute inflammation and swelling, and extend the time available for a non-emergency surgery. A strangulated hernia requires urgent surgery to prevent tissue death and the organs from rupturing.

Consider elective surgery. Even if your hernia is not immediately life-threatening, your doctor might suggest surgery before the condition worsens. Studies have shown that early surgery significantly reduces the risk of complications and death.

Understand the potential outcomes. Depending on the type of hernia and the individual patient's condition, the chances of recurrence can vary.

• Inguinal hernia (children): This type of hernia has a low recurrence rate, under 3% after surgical treatment. Sometimes, it resolves on its own in newborns.
• Inguinal hernia (adults): The recurrence rate after surgery can range from 0-10%, depending on the surgeon's experience.
• Incisional hernia: Approximately 3%-5% of patients will experience a recurrence after the first surgery. If the hernia is large, the recurrence rate can rise to 20%-60%.
• Umbilical hernia (children): This type of hernia typically resolves naturally.
• Umbilical hernia (adults): The recurrence rate of an umbilical hernia in adults is higher, typically reaching 11% after surgery.

• Avoid lifting heavy objects, excessive coughing, or bending forward if you suspect you have a hernia.

• Visit a doctor immediately if you think you may have a hernia. This condition can quickly escalate into a serious issue. Symptoms of an incarcerated hernia include nausea, vomiting, or both, fever, rapid heartbeat, sudden onset of severe pain, or redness and dark discoloration in the protrusion area.
• Emergency hernia surgery typically carries a lower survival rate and higher complication risk compared to elective surgery.
