Inguinal Hernia: Symptoms, Causes & Treatment

An inguinal hernia is the most common type of hernia, occurring when part of the abdominal contents (often part of the intestine or fatty tissue) protrudes through a weak point or opening in the abdominal wall in the inguinal area, the groin region near the lower abdomen. The weak point may be present from birth or develop over time due to repeated pressure on the abdominal wall. Inguinal hernia is many times more common in men than in women due to anatomical differences in this area.

The most prominent sign of an inguinal hernia is the appearance of a bulge or mass in the groin area or scrotum, clearer when standing, coughing, lifting heavy things, or straining, and often disappearing or shrinking when lying down or pressing on it gently. It may be accompanied by a feeling of heaviness, tugging, or mild pain in the area, especially at the end of the day or after exertion. Factors that increase the risk or worsening of a hernia include: lifting weights, chronic cough, chronic constipation and straining during bowel movements, obesity, and pregnancy. Many inguinal hernias cause no severe pain at first.

Although most inguinal hernias are not emergencies in themselves, the most important thing to watch for is the possibility of the hernia becoming incarcerated, meaning part of the intestine gets stuck in the opening and does not return to its place, and this may develop into strangulation where blood flow to the trapped tissue is cut off, an emergency threatening the intestine and requiring immediate surgery. Its warning signs include: a hard, painful bulge that does not go back in, sudden severe pain, nausea and vomiting, and redness of the skin over the hernia. Because a hernia does not heal on its own and only surgical intervention repairs it, the definitive treatment is surgery to return the contents to their place and strengthen the abdominal wall (often with a medical mesh), done laparoscopically or by open surgery. The doctor discusses the timing of surgery according to the hernia's size and symptoms, emphasizing the need for urgent intervention at any sign of incarceration or strangulation.

• A bulge in the groin or scrotum that increases with standing and effort.
• Disappears or shrinks when lying down.
• A feeling of heaviness, tugging, or mild pain especially at the end of the day.
• Warning signs: a hard painful bulge that does not return, severe pain, nausea and vomiting.

• A weak point or opening in the abdominal wall (congenital or acquired).
• Repeated pressure: lifting weights, chronic cough, constipation and straining, obesity, pregnancy.
• More common in men due to anatomy.

• Diagnosis is often clinical from examination (the patient is asked to cough or stand).
• Ultrasound sometimes when the hernia is unclear.
• Urgent evaluation at signs of incarceration or strangulation.

The definitive treatment

• Surgery to return the contents and strengthen the abdominal wall (often with a medical mesh).
• Done laparoscopically or by open surgery.

Timing

• The doctor discusses the timing of surgery according to size and symptoms.
• Urgent intervention at any sign of incarceration or strangulation.

A hernia does not heal on its own. This content is educational and does not replace consulting a surgeon.

• Incarceration of the hernia (tissue stuck and not returning).
• Strangulation of the hernia (cut-off blood flow) — an emergency threatening the intestine.
• Increased hernia size and symptoms over time.

• Maintaining a healthy weight and avoiding lifting weights improperly.
• Treating constipation and chronic cough to reduce pressure on the abdomen.
• Not neglecting a groin bulge and seeing a doctor.
