What is the cause of a hernia?

Nature/Nurture. Most hernias develop due to a "birth defect" of sorts, where natural holes in the abdominal wall present in fetal life fail to close. This may manifest itself at birth or require years of "exertion" before the hole reaches a size large enough to be evident. Other hernias are strictly "wear-and-tear" phenomena, although it is believed that they occur in-part due to inherently weak tissue.
In kids, ... A hernia is usually a congenital hole in the firm layer of the abdominal wall, a fascial defect. Such herniae commonly occur in the groin, beneath the bellybutton, or in the upper abdominal midline. A hernia in an adult could have a congenital origin and show up later, come from weakening of the fascia over time, or occur from separation of the fascia in an old abdominal surgical scar.

Genetics. A groin hernia is when the natural openings in the abdominal wall (through which pass the spermatic cord on men and the round ligament in women) stretch out, and allow other abdominal contents to herniate through. While it can be brought on by coughing, or other sudden increase in abdominal pressure, it is also due to happen more often in those susceptible based on their genetics. Hope this helps!

Nature/Nurture. Most hernias arise as "birth defects" during fetal development, others due to inherent weakness in the abdominal wall, and yet others due to predisposing factors such as prior abdominal surgery, obesity, smoking, chronic steroid use, heavy lifting. Common locations for hernias include the groin, the belly button, and the upper abdomen. Read more...
Many. While the exact cause for a particular person may be unknown, there are many factors that are associated with hernia disease such as collagen disorders which can be genetically determined, previous surgery, infection, trauma, or congenital (born with it).

Regardless of its origin, these will occur more commonly after heavy lifting, obesity, etc. Read more...
