The presence of a hernia can be determined by clinical symptoms and examination findings. If the patient has an inguinal hernia, it will be manifested as a lump protruding outward from the abdomen, and the size of the lump will become smaller, larger or disappear with the change of body position. If the patient has a brain hernia, there will be severe headache, optic nerve disk edema, nausea and vomiting, and the patient may even have blurred consciousness, respiratory arrest, heart rate slowing down and other symptoms. Diaphragmatic hernia, on the other hand, will have symptoms such as acid reflux and heartburn, and a choking sensation when swallowing. Generally patients can do inguinal CT, ultrasound and other tests to determine whether an inguinal hernia occurs. For patients who suspect brain hernia, they need to do CT and MRI of the brain to determine whether there are localized lesions. In addition, patients undergo chest X-ray, chest and abdominal CT examination can determine whether there is a diaphragmatic hernia. For patients with abdominal masses, if the hernia is considered to be the cause, the patient needs to consult a doctor in time for examination, and the doctor will determine the type of hernia and formulate the corresponding treatment based on the patient’s clinical manifestations and examination results.
