The child always coughs, has phlegm, colds and respiratory infections

When children always cough, expectorate, catch colds, or have respiratory infections, it may be due to non-pathological reasons, such as allergic factors, etc. It may also be caused by pathological reasons, such as upper airway cough syndrome, chronic pharyngitis, mycoplasma pneumonia, asthma, etc.

1. Non-pathological causes

If a child is allergic to pollen or dust in the air, it may irritate the child's respiratory mucosa, causing the child to have symptoms such as frequent coughing, sputum, and colds. At this time, you should stay away from allergens in time and follow the doctor's advice to use drugs such as loratadine tablets for anti-allergic treatment.

2. Pathological causes

1. Upper airway cough syndrome: refers to a clinical syndrome with cough as the main manifestation caused by factors such as nasal cavity, sinus, and throat diseases, mainly manifested by cough, sputum, cold, respiratory tract infection, etc. If diagnosed, you can follow the doctor's advice to use glucocorticoid drugs such as budesonide inhalation aerosol to control inflammation and relieve symptoms.

2. Chronic pharyngitis: It is a common respiratory disease, which often develops due to repeated attacks of acute pharyngitis that have not been completely cured. It can also be induced by improper diet, excessive smoking and drinking. After the disease occurs, symptoms such as dry throat, sore throat, cough, sputum, hoarseness and colds will occur. For those with bacterial infections, antibiotics such as penicillin V potassium capsules and cefixime dispersible tablets can be taken as prescribed by the doctor for antibacterial treatment; if it is a viral infection, antiviral drugs such as acyclovir tablets and ribavirin granules are needed to improve the condition.

3. Mycoplasma pneumonia: It is usually an inflammatory disease of the lung parenchyma caused by mycoplasma infection. During the onset of the disease, patients usually experience symptoms such as fever, fatigue, headache, loss of appetite, and cough, sputum, and cold. Once diagnosed, it is necessary to use macrolide antibiotics such as azithromycin for injection and roxithromycin capsules in time for treatment under the guidance of a doctor.

4. Asthma: It is a common disease of the respiratory system. When the body is exposed to allergens, it can induce abnormal immune response, which in turn produces a large amount of secretions and adheres to the respiratory mucosa, causing frequent coughing, sputum, colds, etc. Clinically, it can generally be treated with oral montelukast sodium chewable tablets, compound pholcodine oral solution and other drugs to relieve cough and reduce sputum. If necessary, salbutamol aerosol can be used to relax airway smooth muscles and promote the discharge of blocked secretions.

In addition to the above conditions, whooping cough, measles, influenza, Kawasaki disease, hand, foot and mouth disease, etc. may also cause the above conditions. It is recommended that parents take their children to the hospital for treatment in a timely manner, complete relevant examinations to clarify the specific cause of the disease, and then cooperate with the doctor for targeted treatment. In daily life, you should also pay attention to keeping warm to avoid getting cold and causing the original discomfort to worsen.
