What is a Hernia?

A hernia occurs when an organ or fatty tissue squeezes through a weak spot in the surrounding muscle or connective tissue. This can result in a noticeable bulge under the skin, often accompanied by pain or discomfort. Hernias commonly occur in the abdomen, although they can also develop in other areas such as the groin, belly button, or upper thigh. 

In India, hernias are a significant health concern, with thousands of cases reported each year. Although the prevalence of hernias in India varies across different regions and demographics, they remain a considerable burden on the healthcare system, requiring surgical intervention to prevent complications and alleviate symptoms.

According to medical data available on the internet, hernias are more prevalent in men and older adults, although it can affect both genders and can affect people of any age group. 

According to NCBI, India has 1.5–2 million inguinal hernias, which affects 15–20% of the general population. 

What causes Hernia?

Hernias result from a combination of factors contributing to muscle weakness and strain. They can manifest rapidly or gradually over time due to various underlying causes:

• Congenital conditions – Some hernias stem from developmental anomalies in the womb, persisting from birth and predisposing individuals to herniation later in life.
• Age-related factors – Aging can weaken muscles and connective tissues, increasing susceptibility to hernias as the body’s structural integrity diminishes.
• Trauma and surgical intervention – Previous injuries or surgeries can leave muscles weakened or damaged, creating potential sites for hernias to occur.
• Chronic health issues – Chronic health issues like coughing, constipation, or ascites put prolonged pressure on abdominal muscles, exacerbating the likelihood of hernia development.
• Physical exertion  – Activities involving heavy lifting or strenuous exercise can strain muscles, particularly if not performed with the correct techniques, which can increase the risk of hernia.
• Pregnancy – Multiple pregnancies or excessive weight gain during pregnancy can strain abdominal muscles, making pregnant individuals more prone to developing hernias.
• Obesity – Excess body weight places added stress on the muscles and tissues, increasing the likelihood of hernia formation due to the constant strain on the abdominal wall.

Risk Factors of Hernia

Certain factors can increase your likelihood of developing a hernia. These include:

• Premature birth or low birth weight
• Advancing age
• Chronic coughing, often causing repetitive increases in abdominal pressure
• Cystic fibrosis
• Pregnancy
• Chronic constipation
• Overweight or obesity
• Smoking, as it weakens connective tissue
• Personal or family history of hernias

What are the Symptoms of Hernia?

The primary symptom of a hernia is the presence of a noticeable bulge or lump in the affected area. For instance, with an inguinal hernia, you might observe a protrusion on either side of your pubic bone where your groin meets your thigh.

Typically, you may find that the bulge diminishes when lying down but becomes more apparent when standing, bending, or coughing. Discomfort or pain in the vicinity of the bulge is also common.

Some hernia types, like hiatal hernias, can manifest with more specific symptoms such as heartburn, difficulty swallowing, or chest pain.

In many instances, hernias remain asymptomatic. You may only become aware of a hernia during a medical examination for an unrelated issue or a routine physical check-up.

Common Locations for Hernia

Common locations where hernia may occur include:

• Your lower chest through your diaphragm.
• Your groin through your lower abdominal wall.
• Along the front midline of your abdomen.
• Through a former abdominal surgery incision.

Types of Hernia

Here’s a brief explanation of different types of hernia:

1. Inguinal Hernia – Inguinal hernias occur when tissues, usually part of the intestine, protrude through a weak spot in the abdominal wall in the groin area. They often appear as a bulge on either side of the pubic bone and are more common in men. Straining or heavy lifting can worsen the symptoms.
2. Hiatal Hernia – Hiatal hernias develop when a portion of the stomach protrudes through the diaphragm into the chest cavity. This type of hernia can lead to symptoms like heartburn, regurgitation, and difficulty swallowing, as the stomach acid refluxes into the esophagus.
3. Umbilical Hernia – Umbilical hernia involves a protrusion near the nave, occurring when part of the intestine or abdominal lining pushes through the abdominal wall near the belly button. They are commonly seen in infants and usually resolve spontaneously by age 1, but can persist or develop in adults, often due to increased abdominal pressure.
4. Femoral Hernia – femoral hernias appear as bulges in the upper thigh or groin, below the inguinal ligament. They are more common in women and can occur when tissue, usually intestine, protrudes into the femoral canal. Straining, pregnancy, and obesity can increase the risk of developing a femoral hernia.
5. Incisional Hernia – Incisional hernias occur at the site of a previous abdominal surgery incision. They develop when tissue protrudes through weakened or disrupted muscles or scar tissue. Factors such as obesity, poor wound healing, and excessive strain on the surgical site increase the risk of incisional hernias.
6. Ventral Hernia – Ventral hernias occur in the abdominal wall and can develop anywhere between the chest and groin regions. They can result from surgical incisions, congenital defects, or weakened abdominal muscles due to factors like obesity, pregnancy, or heavy lifting. Ventral hernias may appear as bulges or lumps in the abdomen and cause discomfort or pain, particularly when straining or lifting heavy objects.

How is Hernia Treated?

Hernia can sometimes be managed with medications to alleviate symptoms and exercises to strengthen the surrounding muscles. However, it’s crucial to note that the definitive treatment for hernia is typically surgery. Surgery becomes necessary when the hernia enlarges or protrudes, becomes painful, or poses a risk of complications such as obstruction or strangulation of the herniated tissue.

In hernia repair surgery, the protruding tissue is pushed back into place, and the weakened abdominal wall is reinforced. One common technique involves the use of mesh to provide additional support and reduce the risk of recurrence. Hernia mesh is a synthetic material that is placed over the hernia from recurring by providing support to the surrounding tissue. This minimally invasive procedure is often performed laparoscopically or through open surgery, depending on the size and location of the hernia. Post the hernia repair surgery, patients experience improvement in symptoms and can resume their normal activities with minimal downtime.

Can Hernia be Prevented?

While some factors contributing to hernias, such as genetics or congenital conditions, are beyond one’s control, there are steps individuals can take to reduce their risk of developing a hernia and potentially prevent its occurrence:

• Maintain a healthy weight – Obesity and excess body weight can increase pressure on the abdomen, leading to weakened abdominal muscles and a higher risk of hernia formation. By maintaining a healthy weight through proper diet and regular exercise, individuals can reduce the strain on their abdominal wall and decrease their risk of developing a hernia.
• Practice proper lifting techniques – Improper lifting techniques can put excessive strain on the abdominal muscles and increase the risk of hernia formation. When lifting heavy objects, it’s essential to bend the knees, keep the back straight, and lift with the legs rather than the back. 
• Avoid straining during bowel movements – Constipation and straining during bowel movements can increase intra-abdominal pressure, potentially leading to hernia formation. To prevent constipation, individuals should consume a diet rich in fiber, stay hydrated, and engage in regular physical activity. 
• Quit smoking – Smoking can weaken connective tissues and impair the body’s ability to heal, making individuals more susceptible to hernias. Quitting smoking can not only reduce the risk of hernia formation but also improve overall health and well-being.
• Treat chronic coughing – Chronic coughing due to different respiratory conditions can increase pressure in the abdomen and contribute to hernia formation. Treating these underlying medical conditions can help reduce the risk of hernias.
• Seek prompt medical attention – If individuals notice any symptoms indicative of a hernia, it’s essential to seek prompt medical evaluation and treatment. Early detection and intervention can help prevent complications associated with hernias and reduce the need for more extensive surgical repair.

While hernias cannot always be entirely prevented, adopting healthy lifestyle habits and practicing preventive strategies can significantly reduce the risk of hernia formation.
