Coughing loss is hoarseness caused by coughing, and there are two main types of common causes: 1. local pharyngeal problems, violent coughing, or inflammation of the throat can cause edema and paralysis of the vocal cords, which are the main clinical causes of coughing loss; 2. especially for some middle-aged and elderly people, long-term smoking patients should be vigilant, and when coughing loss is longer, such as more than two weeks, you must go to the hospital for relevant examinations . It is possible that malignant tumor disease, such as lung cancer compressing the recurrent laryngeal nerve or lymphatic metastasis caused by lung tumor, may cause pressure on the recurrent laryngeal nerve and lead to coughing loss of voice. Cough loss is characterized by a hoarse voice that is progressively worse, accompanied by coughing or coughing up sputum, or blood in the sputum. The principle of management of cough loss in the throat is to rest the voice, i.e., to give the vocal cords adequate rest. It is also important to avoid eating irritating foods that may aggravate the condition. Therefore, in the case of coughing loss of voice, targeted etiologic treatment should be carried out for two main categories of causes, with emphasis on finding the possible causes.
