Hernia: Types, Causes, Symptoms, Diagnosis, And Treatment

A hernia is a condition where an organ or tissue protrudes through a weakness or opening in the surrounding muscle or connective tissue. It often occurs in the abdominal wall, causing a visible bulge that may become more prominent when straining or bearing down. 

The most common signs and symptoms of hernia include pain, discomfort, and mild swelling near the abdomen area or groin. Most hernias are not life-threatening, but if it gets stuck in the hole that’s pushed through and can’t go back, then it may require surgery. So, what exactly is a hernia? And what are its types, causes and symptoms? Let’s find all the answers related to hernia in this blog. 

Understanding Hernia

A hernia occurs when an organ pushes through an abdominal opening in the muscle or tissue. Most hernias occur in the area between the chest and hips, but they can also appear in the upper thigh and nearby groin areas. 

Most hernias involve the bowel or peritoneum (the membrane lining the abdominal cavity) pushing through a gap in the abdominal wall. While some hernias may not cause problems, depending on their location and size, others can lead to discomfort, pain, or potential complications. 

Overview of hernia as per the Scrip study:

Hernia treatment options range from watchful waiting to surgical repair, based on the severity of the condition.

Types of Hernias

Different types of hernias are discussed as follows: 

1. Inguinal Hernia

An inguinal hernia occurs in the lower part of the abdomen (inner groin area) and protrudes into the right or left inguinal canal. If you have a hernia, the inguinal canal is a passageway that runs down the inner thigh, resulting in a protruding bulge. It’s the most common type, affecting over 1.5 to 2 million people in India. It is highly common in males, people ages 75–80, and children ages 0–5.

2. Femoral Hernia

A femoral hernia (or femorocele) is a less common type of hernia that occurs in the femoral canal. It appears as a painful bulge in the upper part of the thigh or outer groin. Femoral hernia affects only 3% of people and is more common in women than in men. 

3. Hiatal Hernia

Hiatal hernia is another common type of hernia that affects more than 1 million people in India. It occurs when the upper part of the stomach bulges into the chest through an opening in the diaphragm. The primary cause of this is acid reflux, which is treatable with some lifestyle changes.

4. Congenital Diaphragmatic Hernia

Congenital diaphragmatic hernia is a rare disorder that arises during fetal development. It happens when abdominal organs move into the thoracic cavity while they are still growing. It is a significant developmental abnormality which impairs the baby's growth. It is frequently classified based on the location of the diaphragm abnormality and may have some link to a genetic condition or mutation.

5. Incisional Hernia

Incisional hernias occur when the abdominal muscles weaken and tissue or organs push through, producing a bulge. It results from a surgical incision or cut in the abdominal wall that fails to heal properly after surgery. Mid-line incisional hernias are more common but can be treatable.

6. Umbilical Hernia

An umbilical hernia is a condition characterized by a tissue bulge or swelling near the belly button (navel). It occurs when a part of the intestine bulges through the opening in the abdominal muscles. They’re usually harmless in children but more serious in adults. It is another common type of hernia that affects over 1 million people in India but can be treatable with proper medical procedures.

Causes and Risk Factors

Some of the most prevalent causes of hernias include:

• A congenital condition (during the baby’s developmental period),
• Aging,
• Failing in post-surgery healing or injury,
• Strenuous workouts or carrying hefty weights,
• Pregnancy,
• Constipation,
• Obesity,
• Enlarged prostate,
• Straining to urinate,
• Abdominal fluid.

Several risk factors can contribute to a hernia, including:

• Premature baby birth,
• Low baby weight,
• Being older,
• Chronic cough or allergies,
• Cystic fibrosis,
• Pregnancy (particularly repetitive),
• Chronic constipation,
• Chronic obesity,
• Smoking and drinking,
• Heredity,
• Poor diet.

Symptoms and Signs

Some hernias may not show any signs or symptoms. However, the most common symptoms of hernias include:

• A bulge or lump in the area near Gorin or abdomen,
• Chest pain,
• Burning sensations,
• Heaviness or discomfort, especially while coughing,
• Tugging feeling around the lump or bulge,
• Vomiting,
• Constipation.

In the case of a hiatus hernia

• Heartburn,
• Acid reflux,
• Pain in the chest or stomach,
• Difficulty swallowing.

In cases of inguinal hernia

• Weakness or pressure in the groin,
• Swelling and pain around the testicles,
• In babies, inguinal hernia is usually soft, smooth, and painless. 

Diagnosis and Evaluation

To diagnose the hernia, the doctor starts with a simple physical exam. The doctor may ask for a cough, strain, or stand while pressing the hernia. If they feel a bulge or lump in the abdominal or groin area, they may take a medical history of the patient. The doctor can further ask for some abdominal imaging tests, such as 

• Ultrasound
• Computed tomography (CT scan)
• Magnetic Resonance Imaging (MRI)
• X-ray
• Endoscopy

Take note that these screening tests are not necessary for everyone.

Treatment Options

Most hernia patients do not require treatment since no symptoms develop. However, femoral hernias can be risky, and the risk is four times higher in females than males. The size and severity of the hernia determine whether surgery is necessary. If the hernia indicates any potential complications, the doctor may advise patients to wait for a while. 

• If they are not showing any symptoms, they will keep it undisturbed until it becomes painful. 
• If a person has any symptoms, their doctor may suggest hernia repair surgery. 

Moreover, the hernia can be controlled by wearing a belt-like device called a truss. It is temporary and applies external compression, pushing the bulging tissues or organs back into the abdomen.

Watchful Waiting

Most hernias require surgical repair, but not necessarily immediately. If you have a small or mild hernia and do not show any symptoms that only come out occasionally, your healthcare provider may take a wait-and-watch approach to see if it worsens. A person can wait for the hernia surgery for months to years, although it depends on the symptoms.

Hernia Repair Surgery

Hernia repair surgery is common and generally a minimally invasive method. In this procedure, the surgeon pushes the herniated tissue back and reinforces the barrier with stitches or mesh. It is a minor procedure often used and results in smaller incisions, less postoperative pain, and faster recovery. Only if a hernia grows larger or causes pain does a surgeon decide to repair it with hernia repair surgery.

There are two main types of hernia repair surgeries: open surgery and laparoscopic surgery.

Open Surgery

Some cases may require open surgery, a traditional method for hernias. Open surgery involves making an incision close to the hernia and then pushing the protruding tissue back into the abdomen. After surgery, surgeons repair the hole in the abdominal wall with stitches.

Laparoscopic Surgery

Laparoscopic surgery simply involves a few minor incisions and causes minimal damage to the surrounding tissue. The surgeon uses a laparoscope (a long, thin tube with a lighted camera) to view the surgical site that goes into one small hole. Moreover, the long, thin surgical tools are used through another small hole to operate a hernia.

Note: 

• Robotic surgery for hernia repair is similar, but the surgeon controls the tools from a computer console.

Post-Treatment Care

After hernia repair surgery, you will have to stay in the hospital for 1-2 days, and then you will be discharged. You need to follow some precautions after surgery:

• Clean the wound regularly.
• Keep the incisions dry and clean.
• A healthy and balanced diet should be rich in fiber. 
• Drink at least eight glasses of water a day.
• Avoid swimming.
• Avoid sexual activities.
• Do not lift heavy weights.
• Avoid strenuous exercise.
• Don’t take a hot bath.
• Avoid smoking and drinking.
