What Is a Double Hernia? Causes, Symptoms & Treatment

A hernia occurs when an internal organ or fatty tissue pushes through a weak spot in the surrounding muscle or connective tissue, creating a noticeable bulge. This article clarifies what constitutes a “double hernia,” how it is identified, its contributing factors, and available treatment approaches.

Understanding Double Hernias

While a single hernia is common, a “double hernia” refers to the presence of two distinct hernias. This can mean two hernias of the same type occurring bilaterally, such as one on each side of the groin, or two different types of hernias located in separate areas of the body.

The most common type of hernia that appears bilaterally is an inguinal hernia, where tissue protrudes through a weak spot in the abdominal muscles in the groin area. These are frequently observed in men and can occur on both the right and left sides. Other types of hernias that may present bilaterally or concurrently with an inguinal hernia include femoral hernias, which appear in the upper thigh, and umbilical hernias, near the belly button.

Identifying Double Hernias

Recognizing the signs of a double hernia often begins with observing a visible bulge. This lump typically becomes more apparent when standing upright, coughing, straining, or lifting. While some hernias may not cause pain initially, discomfort can develop over time, particularly during activities that increase abdominal pressure. Common symptoms include a burning or aching sensation at the bulge, pressure in the groin, and a heavy or dragging feeling.

A healthcare professional typically diagnoses a double hernia through a physical examination. During this exam, the doctor may ask the patient to stand and cough or strain to make the bulges more prominent. If the hernia is not immediately visible or palpable, imaging tests such as an abdominal ultrasound, CT scan, or MRI may be used to confirm the diagnosis and assess the extent of the condition. These imaging techniques help visualize the herniated tissue and the underlying muscle wall defect.

Factors Contributing to Double Hernias

Hernias, including double hernias, develop when there is a combination of pressure and a pre-existing weakness or opening in the muscle or connective tissue. This weakness can be present from birth due to incomplete closure of the abdominal wall during development. Over time, the muscles and tissues can also weaken due to aging or repetitive stress.

Increased pressure within the abdomen is a significant contributing factor to hernia formation. Activities such as chronic coughing, straining during bowel movements due to constipation, and heavy lifting can exert considerable pressure on the abdominal wall. Other factors like obesity and pregnancy also increase intra-abdominal pressure, raising the risk of developing hernias. Genetic predisposition can also play a role, as some individuals may inherit a weaker abdominal wall structure, making them more susceptible to multiple hernias.

Treatment Options

Surgical repair is the primary and most effective treatment for double hernias, as hernias do not resolve on their own. The main goal of surgery is to push the protruding tissue back into its proper position and reinforce the weakened abdominal wall. There are two common surgical approaches: open repair and laparoscopic (minimally invasive) repair.

Open hernia repair involves a single incision near the hernia site, through which the surgeon repositions the tissue and stitches the weakened area. A synthetic mesh is often sewn into place to strengthen the abdominal wall and reduce recurrence. Laparoscopic repair uses several small incisions, a thin tube with a camera (laparoscope), and specialized instruments. This method often results in less pain and a quicker recovery, and is frequently preferred for bilateral hernias as both sides can be addressed in one procedure. Consulting with a healthcare professional is important to determine the most suitable treatment plan.
