Inguinal hernias can be classified into two main groups in the classification: congenital and acquired. Congenital inguinal hernias are essentially caused by congenital factors, presenting with symptoms after birth or at an early age, or occasionally not until the young adult stage, and are associated with an unclosed sphincter. Therefore, as an individual, congenital factors cannot be overcome and are difficult to prevent at the root. The main thing that can be done is to avoid prematurity. Nowadays, assisted reproduction is becoming more and more developed and twins and multiples are becoming more and more common. Acquired hernia is often the result of a mixture of congenital and acquired factors, mostly in middle and old age, and is largely related to aging and increased abdominal pressure. No one is immune to aging, but many of the factors that cause increased abdominal pressure are potentially preventable. Therefore, the prevention of small bowel gas is mainly aimed at diseases with increased abdominal pressure among the acquired factors, that is, avoiding the causes of long-term increased abdominal pressure. Here are some examples: 1, the old slow patients: as far as possible to control the symptoms, reduce the duration of chronic cough and phlegm; 2, constipation: eat more vegetables and fruits honey to keep the stool open, if necessary, some laxative; 3, prostate enlargement patients: urology timely treatment to improve urinary symptoms; 4, cirrhosis ascites patients: because a large amount of ascites can easily lead to the occurrence of inguinal hernia, so as far as possible to control the amount of ascites; 5, healthy women: avoid oversized fetuses and excessive amniotic fluid during pregnancy, and prevent excessive thinness in older women; 6, old smokers: quit smoking and smoke less because there is clear evidence that the incidence of smoking is higher than that of non-smoking populations. Moderate exercise can maintain a certain level of muscle strength to reduce the incidence. Of course, the incidence of inguinal hernia increases with long life expectancy, especially at advanced age, and with the presence of congenital factors, inguinal hernia cannot be 100% prevented. According to the current medical level of hernia specialists in Shanghai, 99% of inguinal hernia patients can be cured.
