How is a cough caused, and how is a cough caused?

There are many causes of cough. The common ones are: 1infections (e.g. bronchitis, pneumonia, etc.); 2.

allergic diseases (e.g., asthma, allergic rhinitis); 3. Chronic obstructive pulmonary disease (COPD); 4.bronchiectasis; 5.Nasopharyngeal diseases that cause runny nose to reflux (eg, chronic rhinitis, allergic rhinitis, sinusitis, chronic pharyngitis, chronic nasopharyngitis, etc., collectively referred to as "upper airway cough syndrome").

6.Gastroesophageal reflux disease (reflux esophagitis, GERD). Targeted examinations such as chest X-ray, chest CT, bronchial provocation test, pulmonary function, flexible bronchoscopy, 24-hour esophageal pH test, sinus CT, nasal endoscopy, allergen prick test, etc., are required, and corresponding medications are taken after diagnosis.

It is usually caused by an upper respiratory tract infection.

For example, laryngitis, diseases of the lungs, diseases of the cardiovascular system, diseases of the mediastinum, etc.

Common disorders that cause cough in this paragraph.

1 Upper respiratory tract infection: A cold is caused by the virus entering the human body through the nose and throat, causing inflammation of the mucous membrane of the upper respiratory tract. When a child has a cold, he or she usually has a cough.

2 Bronchitis: Most of them are due to the spread of upper respiratory tract infections, the onset is more acute, at first it is mostly dry cough, followed by cough, phlegm and other discomforts, and in severe cases, hypoxia occurs due to dyspnea, and the lips turn blue and purple. 3 Pneumonia:

Most children under the age of 2 years have bronchopneumonia, which is mostly caused by upper respiratory tract infection or bronchitis. Generally, there will be a dry cough, shortness of breath, cyanosis of the lips, and a flapping of the nasal wings. With the exception of newborns, it is common to have a fever up to 39 .

4 Acute laryngitis: Throat infections can also occur when viruses or bacteria pass through the larynx. In addition to dry cough and throat pain, the most typical symptom of acute laryngitis is hoarseness or even inability to make a sound.

It makes a canine-like coughing sound when inhaling air, and in severe cases, a laryngeal roar occurs.

Cough is generally caused by a cold, will form bronchitis, cough must not smoke again, it is best to take a little anti-inflammatory medicine or go to the hospital to check it, only in this way can you cough.

1. The most common acute cough is the common cold, and others include acute bronchitis, acute sinusitis, allergic rhinitis, acute attack of chronic bronchitis, bronchial asthma, etc.

2. The most common causes of subacute cough are post-infectious cough, bacterial sinusitis, bronchial asthma, etc.

3. There are many causes of chronic cough, which can usually be divided into two categories: one is those with clear lesions on chest X-ray in the initial examination, such as pneumonia, tuberculosis, lung cancer, etc.; The common causes of chronic cough include cough variant asthma, upper respiratory tract syndrome, eosinophilic bronchitis and gastroesophageal reflux cough, which account for 70% to 95% of chronic cough in respiratory medicine outpatient clinics.

Cough is a common respiratory symptom, and the causes of cough are common in inhalation of dust mites, pollen, fungi, animal dander, etc.; Respiratory infections and coughs can be triggered by changes in air temperature, temperature, air pressure, and/or ions in the air, and some coughs after strenuous exercise.

Coughing is a reflex action in which air is quickly expelled from the lungs to clear excess secretions, fluids, or foreign bodies from the respiratory tract, so coughing is an important respiratory defense mechanism.
