What kind of hernia is dangerous?

Hernias are common medical conditions that affect people of all ages and backgrounds. They occur when an internal organ or tissue pushes through a weakened or damaged muscle or connective tissue. While hernias can be uncomfortable and require medical attention, not all are equally dangerous. In this article, we’ll explore the different types of hernias, when its generally considered the most dangerous, and delve into the available treatment options.


Understanding Hernias:

A hernia occurs when there is a gap or weakness in the muscle or connective tissue that holds internal organs in place. This opening allows organs or tissues to bulge through, often creating a noticeable lump or bulge under the skin. Hernias can occur in various parts of the body, with the most common types being:


Inguinal Hernias:

This is the most common type of hernia and typically affects men. It occurs when a portion of the intestine or fatty tissue protrudes through the abdominal wall or into the groin area.

Umbilical Hernias:

Occurring in the area around the navel (belly button), this type of hernia involves a protrusion of tissue through the abdominal wall. It’s more common in infants but can also affect adults.

Incisional Hernias:

Incisonal hernias develop at the site of a previous surgical incision. It involves tissue pushing through a weakened area in the abdominal wall.

Hiatal Hernias:

This type differs from the others as it involves the stomach pushing up through the diaphragm into the chest cavity. It can lead to acid reflux and other digestive symptoms.

Femoral Hernia:

More common in women, femoral hernias occur when tissue pushes into the femoral canal, a passageway near the groin.

When Is Hernia Dangerous?

The danger associated with hernias primarily depends on the risk of complications. In this regard, strangulated hernias are generally considered the most dangerous. A strangulated hernia occurs when the blood supply to the trapped tissue or organ is cut off. This can lead to tissue damage or even tissue death (necrosis), which is a medical emergency. In such cases, immediate surgical intervention is necessary.

Certain types of hernias are more likely to become strangulated than others due to their location and characteristics. Here are the hernia types that are most commonly associated with the risk of strangulation:

  1. Inguinal Hernias: Inguinal hernias are more likely to become strangulated because of their location near the inguinal canal. Inguinal hernias can trap a loop of the intestine or other tissue, leading to strangulation.
  1. Femoral Hernias: Femoral hernias are at a higher risk of becoming strangulated because of their narrow opening, which can easily trap and compress tissue.

It’s important to note that while these types of hernias are more likely to become strangulated, any hernia can potentially lead to strangulation if the herniated tissue becomes trapped or compromised.

Why Strangulated Hernias Happen:

Strangulated hernias occur when the blood supply to the protruding organ or tissue within the hernia is cut off or significantly reduced. This happens typically as the result of one or more of the following factors:


Strangulated hernias often occur when the herniated organ or tissue becomes trapped within the hernia sac. This can happen when the opening through which the hernia protrudes narrows or tightens, preventing the tissue from returning to its normal position.

Increased Pressure:

Factors that increase abdominal pressure, such as heavy lifting, persistent coughing, or straining during bowel movements, can contribute to the constriction of the hernia’s blood vessels. Increased pressure can also cause the hernia to become incarcerated (trapped) before progressing to strangulation.


In some cases, the tissue or organ within the hernia sac can become inflamed due to irritation or infection. Inflammation can further constrict blood vessels, reducing blood flow to the trapped area and leading to strangulation.

Twisting or Torsion:

Certain types of hernias, such as an incarcerated inguinal hernia or a volvulus (twisting of the intestine), can cause a torsion or twisting of the affected tissue. This twisting can quickly compromise blood flow, leading to strangulation.

Strangulated hernias are considered a medical emergency because the lack of blood supply can cause the trapped tissue or organ to become ischemic (deprived of oxygen and nutrients), leading to tissue damage and, if not promptly treated, tissue death (necrosis). This can result in severe pain, fever, and other symptoms. Left untreated, a strangulated hernia can lead to life-threatening complications, such as gangrene and sepsis.

If you suspect you have a strangulated hernia or experience symptoms such as severe abdominal pain, nausea, vomiting, fever, or a firm, tender lump at the hernia site, seek immediate medical attention. Prompt surgical intervention is required to restore blood flow to the trapped tissue and prevent further complications.

Hernia Treatment Options:

Ignoring hernias can be life-threatening. If left untreated, hernias can lead to severe complications, including:

Strangulation: Hernias can become incarcerated, where the tissue becomes trapped and loses its blood supply, leading to tissue death (necrosis) and infection.

Bowel Obstruction: A hernia can obstruct the bowel, causing severe pain and potentially leading to bowel tissue damage.

Treatment Options

Treatment for hernias typically involves surgical repair. The goal of hernia surgery is to return the displaced tissue or organ to its proper position and strengthen the weakened area of the muscle or tissue. Common hernia repair methods include:

1. Open Surgery: This involves making an incision at the hernia site, pushing the protruding tissue back into place, and repairing the weakened muscle or tissue with sutures or mesh.

2. Laparoscopic Surgery: Also known as minimally invasive surgery, this approach involves smaller incisions and using a camera as well as specialised instruments. It often results in shorter recovery times.

3. Hiatal Hernia Repair: Hiatal hernias are often treated with medication to manage acid reflux. Surgical intervention may be necessary for severe cases.

In conclusion, while all hernias require medical attention, strangulated hernias are generally considered the most dangerous due to the risk of tissue strangulation and necrosis. However, the severity of a hernia also depends on various factors such as the individual’s overall health and the promptness of medical treatment. If you suspect you have a hernia or are experiencing symptoms, it’s essential to consult a doctor who can provide an accurate diagnosis and recommend the most appropriate treatment plan. Early intervention is often key to preventing complications and ensuring a successful recovery.
