Don’t look at the diaphragm as a thin membrane, but the role it plays in the body cannot be ignored. Diaphragmatic hernias in areas like this one are very rare in adults and can be very easily misdiagnosed. Diaphragmatic hernia is the most common type of diaphragmatic disease. Symptoms of diaphragmatic hernia vary in severity and depend mainly on the size of the abdominal organ volume herniated into the chest. In patients with severe symptoms, even the entire stomach may run from the abdominal cavity into the thoracic cavity. At this point, the patient may experience nausea and vomiting. In more serious cases, even the intestines within the lower abdomen will run into the chest cavity, which will not only cause constipation, etc., but even the organs within the chest will be squeezed as a result, causing serious consequences such as chest tightness, shortness of breath, difficulty in breathing, rapid heart rate, etc. In serious cases, it may even cause ischemic necrosis and perforation of the stomach and intestines by compression, which is life-threatening. Once a diaphragmatic hernia is detected, surgical repair is the most fundamental treatment, because the hernia will not go away on its own, but will get bigger and bigger over time, and thus the symptoms will become more and more severe, so timely surgery is necessary once it is detected. So how exactly does diaphragmatic hernia trigger? Director Xu said that diaphragmatic hernia is partly caused by congenital dysplasia of the diaphragm, which is more common in children but rare in adults. Some of them are also caused by acquired abdominal trauma that tears the diaphragm. There is another type of diaphragmatic hernia called esophageal hiatus hernia, which is common in elderly people and is caused by weakness of the diaphragm at the esophageal hiatus.
