Cough is one of the most common symptoms after COVID-19 infection. In view of persistent cough, Fu Guiling, the chief physician of Changping District Integrated Hospital of Traditional Chinese and Western Medicine, reminded that the spleen and kidney might be injured if the cough did not heal for a long time, and should be treated in time to prevent small lesions and serious diseases. Fu Guiling said that cough can be divided into exogenous cough and internal injury cough. Cough caused by COVID-19 infection is exogenous cough. Food therapy is often used for light cough, which is applicable to prevention at ordinary times, during illness and after rehabilitation. Common food therapy prescriptions include: boiled snow pear, steamed Sichuan fritillary pear, stewed snow pear with rock sugar, steamed orange, stewed loquat peel with lily, white radish, tremella fuciformis soup, moistened lung cabbage soup, etc. Fu Guiling reminds that lying flat can easily lead to the accumulation of respiratory secretions, which can aggravate the cough. If the cough is serious, you can raise your head, which is conducive to smooth breathing and expectoration. During coughing, the diet should be light, nutritious and easy to digest. Avoid cold, greasy and spicy food. Avoid salty and sweet food. People with history of cerebrovascular rupture, embolism or hemangioma should avoid coughing forcefully. "Food therapy alone is not enough for those who have severe symptoms and can't recover from a long cough." Fu Guiling said that if the exogenous cough attacks repeatedly, it may turn into a chronic internal injury cough, and a long cough will hurt the spleen and kidney. "We should pay attention to the treatment of cough and not shoulder it hard to prevent small lesions and serious diseases." Traditional Chinese medicine has obvious efficacy in the treatment of cough and asthma. People who still cough after "Yangkang" can go to the relevant department of the hospital nearby to prescribe medicine. (Outlook New Times)
