Depending on the cause, inguinal hernias are broadly classified as congenital or acquired. The former is caused by changes in the position of the testes during development. The testes are located in the abdominal cavity during fetal life and gradually descend into the scrotum as they grow and develop. Because the right side of the testicle descends later than the left side, this hernia is more likely to occur on the right side. In females, this hernia is almost never present. It is possible that this hernia will disappear on its own with growth, and if surgery is performed in childhood, it usually does not recur because there is nothing inherently wrong with the abdominal wall of the child. Acquired inguinal hernias are a more common type of hernia and are caused by two main factors: weakness of the abdominal wall and increased abdominal pressure. The fundamental reason why inguinal hernias are almost uniquely human is that humans, as an erect animal, have a congenital structural defect in the inguinal region. Because there is no muscle coverage in this region, but only a layer of transversal abdominal fascia against the pressure of the abdominal cavity, which is highest in humans when the viscera are falling in an upright situation, this innate structural deficiency leads to the possibility of hernia in humans. Some people are prone to hernia when they have poorly developed muscles in this region, or poorly positioned muscles, or poorly developed transversus abdominis fascia. Older adults have atrophied abdominal muscles and decreased strength, thus predisposing them to inguinal hernias. Increased abdominal pressure is a direct cause of hernias. Many soccer stars have hernias, such as Carlo, Kaka, Benzema, Rooney, Shepchenko, Drogba, etc. All of them are physically fit and should have no problems with the strength of the abdominal wall, but they all suffer from inguinal hernias because these athletes often play strenuous sports and overexertion often causes a sudden increase in abdominal pressure, resulting in a tear of the transversal abdominal fascia and thus a hernia, making athletes a high-risk group for hernias. In addition to sports, many situations in daily life can lead to an increase in abdominal pressure, such as heavy physical work, getting up and lifting heavy objects, prolonged standing labor or prolonged walking, etc. People with this type of work are also a good candidate for hernia, and many patients suddenly find a lump in the groin area when they are doing physical work. The onset of hernia is also closely related to many other diseases, such as constipation, forceful defecation and urination due to prostatic hypertrophy, chronic cough, asthma, obesity, ascites, etc. These diseases tend to lead to an increase in abdominal pressure, and people with the above-mentioned conditions are also a high incidence group for hernia. In these patients, if the primary disease is not controlled in time, the state of high abdominal pressure cannot be removed and the hernia will not only not get better, but also develop faster and the chance of danger such as ingrowth will be greatly increased.
