Causes
Some inguinal hernias have no apparent cause. Others might occur as a result of:
- Increased pressure within the abdomen
- A preexisting weak spot in the abdominal wall
- Straining during bowel movements or urination
- Strenuous activity
- Pregnancy
- Chronic coughing or sneezing
In many people, the abdominal wall weakness that leads to an inguinal hernia occurs prior to birth when a weakness in the abdominal wall muscle doesn’t close properly. Other inguinal hernias develop later in life when muscles weaken or deteriorate due to aging, strenuous physical activity or coughing that accompanies smoking.
Complications
Complications of an inguinal hernia include:
- Pressure on surrounding tissues. Most inguinal hernias enlarge over time if not repaired surgically. In men, large hernias can extend into the scrotum, causing pain and swelling.
- Incarcerated hernia. If the contents of the hernia become trapped in the weak point in the abdominal wall, the contents can obstruct the bowel, leading to severe pain, nausea, vomiting, and the inability to have a bowel movement or pass gas.
- Strangulation. An incarcerated hernia can cut off blood flow to part of your intestine. Strangulation can lead to the death of the affected bowel tissue. A strangulated hernia is life-threatening and requires immediate surgery.
Prevention
You can’t prevent the congenital defect that makes you susceptible to an inguinal hernia. You can, however, reduce strain on your abdominal muscles and tissues. For example:
- Maintain a healthy weight. Talk to your doctor about the best exercise and diet plan for you.
- Emphasize high-fiber foods. Fruits, vegetables and whole grains contain fiber that can help prevent constipation and straining.
- Lift heavy objects carefully or avoid heavy lifting. If you must lift something heavy, always bend from your knees — not your waist.
- Stop smoking. Besides its role in many serious diseases, smoking often causes a chronic cough that can lead to or aggravate an inguinal hernia.
