1. How does an abdominal wall hernia develop? If the patient is a child, the cause of abdominal wall hernia is due to the lack of development during the fetal period, resulting in defects in the development of a part of the abdominal wall, such as incomplete umbilical ring atresia, abdominal white line defect, etc. If the patient with ventral wall hernia is an adolescent, an adult, or an elderly person, it is often due to abdominal wall injury caused by late bad habits, excessive exercise, surgical incisions, trauma, and weak abdominal wall muscles in the elderly are prerequisites for the occurrence of ventral wall hernia. 2.What are the symptoms of abdominal wall hernia? Ventral wall hernia often has a prominent mass protruding from the abdominal wall, which is likely to descend into the scrotum and enlarge it if left untreated for a long time. It appears when the patient stands, exerts himself, coughs, or exercises, and disappears when the patient rests quietly and calmly. When the mass protrudes and we gently push upward with our hands there is a slight feeling of resistance which then disappears quickly, and then a grunting sound is heard at the same time. Patients with abdominal wall hernia often have a feeling of falling and some physical discomfort when the mass is protruding, and when long-term abdominal wall hernia is not treated, patients will successively develop lower abdominal cramps, abdominal pain if hernias are ingrown or strangulated, abdominal distension and other signs and symptoms of intestinal obstruction. 3.What are the dangers of ventral hernia? Ventral wall hernia cannot be treated carelessly, except for individual infants who can heal themselves, most of the patients cannot heal themselves and need to go to regular hospital for treatment as early as possible. Only early treatment can get rid of the damage of hernia, otherwise, its condition will deteriorate as time grows, causing local distension and pain and affecting the quality of life in mild cases; in severe cases, when the small intestine protrudes from the hernia ring and gets stuck and cannot return to the abdominal cavity, it can be accompanied by severe abdominal pain and abdominal distension. If not treated in time, the protruding small intestine will be stuck more and more tightly and eventually necrosis will occur due to ischemia. In some cases, it will be life-threatening. Therefore, it is important to find out early and go to a regular hospital for treatment.
