Diaphragmatic palsy is a paralytic rise of the diaphragm on one or both sides with impaired movement due to damage to the phrenic nerve and blockage of nerve impulses. It has a wide range of etiologies, most commonly caused by lymph node compression or invasion of the phrenic nerve by lung cancer metastasizing to the mediastinum. Other conditions such as anterior spinal cord horn infection, motor nerve unit disease, herpes zoster, tuberculosis, diphtheria, pericarditis, mediastinitis, pneumonia, lead poisoning, giant aortic aneurysm, deep neck surgery or trauma, excessive neck strain during childbirth, and inadvertent nerve injury during thoracic surgery can also involve the phrenic nerve and cause diaphragmatic paralysis. In some patients, the cause is unknown. Long-term diaphragmatic palsy can produce atrophy of the diaphragm to form a membrane. So what are the dietary contraindications for patients with diaphragmatic palsy? 1, avoid eating spicy and stimulating food; 2, avoid eating too salty, greasy food.
