What causes dry cough? Two factors are the main causes

Generally speaking, when we cough, droplets will appear. Even if there are no droplets, something will be coughed out. In clinical practice, there is a symptom called dry cough. Patients with this symptom will not cough out anything no matter how hard they "cough". So, what is dry cough?

Physical factors

The patient's constitution includes subjective conditions such as genetics, immune status, mental and psychological status, endocrine and health status, which are important factors that make the patient susceptible to allergic cough. Environmental factors include various allergens, irritating gases, viral infections, residential areas, living conditions, occupational factors, climate, drugs, exercise (excessive ventilation), food and food additives, eating habits, social factors and even economic conditions, which may be more important causes of the occurrence and development of allergic cough. The increasing trend of the incidence of allergic cough is also related to the susceptibility caused by the patient's allergic constitution and environmental factors.

Disease factors

Chronic dry cough can also be called chronic cough. In clinical practice, cough is usually the only or main symptom for more than 8 weeks, and the chest X-ray is normal, which is called chronic cough of unknown cause, or chronic cough for short. Chronic cough involves many reasons, that is, "Suwen·Kelun" says: "All the five internal organs and six bowels can cause cough, not just the lungs." Although cough is a lesion of the lung system, dysfunction of other internal organs may affect the lungs, causing poor lung qi, and cough due to lung qi rising, so there are ten coughs such as "liver cough" and "stomach cough".
