Should children with yellow phlegm be treated? What should children with yellow phlegm be treated?

If you cough with yellow sputum, you need to find the cause in time. For example, children with upper airway cough syndrome have thick nasal discharge that flows into the throat. At this time, the cough may not be sputum, but nasal discharge. The treatment is mainly to treat rhinitis; children with bronchitis who cough with yellow sputum need timely treatment. It is very important to draw out the sputum, that is, to perform airway management.

Coughing with yellow phlegm is usually caused by bacterial infection, and you need to take anti-inflammatory drugs. However, if you take anti-inflammatory drugs, it is best to take them under the doctor's orders. Don't take them blindly. When you have a cough, you must pay more attention to rest, drink more water, and eat light, spicy and stimulating foods. Otherwise, eating less will affect your body's recovery. So, does a child's cough with yellow phlegm need to be treated?

When the entire respiratory mucosa from the nasopharynx to the bronchiolar tuberculosis is irritated, coughing can occur. When secretions, exudates, and leaks in the alveoli enter the bronchiolar tuberculosis, coughing can occur, or certain chemical irritations distributed in the C fiber endings of the lungs can also cause coughing. For example, pharyngitis, laryngeal tuberculosis, laryngeal cancer, etc. can all cause dry coughs, and tracheitis, bronchitis, bronchiectasis, bronchial asthma, bronchial tuberculosis, and various physical (including foreign bodies), chemical, and allergic factors that stimulate the trachea and bronchi, as well as lung bacteria, tuberculosis, fungi, viruses, mycoplasma or parasites, and lung tumors can all cause coughs. Respiratory tract infections are the most common causes of coughing and expectoration.

1. Pleural diseases

Pleurisy caused by various reasons (tuberculosis, pneumonia, systemic lupus erythematosus, rheumatoid arthritis, etc.), pleural mesothelioma, spontaneous pneumothorax or pleural effusion or thoracentesis can all cause cough.

2. Cardiovascular disease

When left heart failure caused by mitral stenosis or other reasons causes pulmonary congestion or pulmonary edema, cough may be caused by serous or bloody exudates in the alveoli and bronchi. In addition, cough may also be caused by pulmonary embolism caused by the detachment of thrombi from the right heart or systemic circulation veins.

3. Central nervous system factors

Impulses are sent from the cerebral cortex to the medullary cough center, and people can cause or suppress cough reflexes at will. For example, when the skin is stimulated by cold or the nasal mucosa distributed by the trigeminal nerve and the mucosa in the area innervated by the glossopharyngeal nerve are stimulated, coughing can be reflexively induced. Coughing can also occur in encephalitis and meningitis.

4. Chronic cough caused by other factors

Such as cough after taking angiotensin-converting enzyme inhibitors, cough caused by gastroesophageal reflux disease, habitual and psychological cough, etc.

In general, mild and infrequent coughs can be relieved naturally by expelling sputum or foreign bodies, without the need for antitussive drugs. However, for those severe dry coughs without sputum, or frequent severe coughs with sputum, it not only increases the patient's pain, affects rest and sleep, increases physical exertion, and even promotes the development of the disease and produces other complications. At this time, the disadvantages outweigh the advantages. Therefore, antitussive drugs should be used appropriately to relieve coughs.

However, most cough suppressants only suppress the cough symptom itself and cannot eliminate the real cause of the cough. To treat cough, the most fundamental way is to eliminate the cause and underlying disease that causes the cough.
