Hernia-induced vomiting is a relatively rare condition, and it is recommended that the cause of vomiting be diagnosed at a nearby regular hospital. If a hernia is diagnosed as the cause, surgical treatment is recommended. Various types of hernia that cause vomiting are more serious, such as a refractory hernia or an incarcerated hernia. A refractory hernia is mainly characterized by the inability of the hernia sac to be retracted into the abdominal cavity, when the contents of the hernia become more and more numerous and therefore also compress the abdominal cavity, leading to an increase in intra-abdominal pressure. The contents of the abdominal cavity will protrude more and more outward, and more protrusion of the intestinal canal may lead to vomiting. In an incarcerated hernia, the intestinal canal may be present in the hernia sac and form an obstruction, or multiple intestinal collaterals may be present in the abdominal cavity and in the hernia sac, divided and narrowed by the hernia sac neck. The most typical symptoms of intestinal obstruction are vomiting and pain.
