What is dry cough?

Dry cough is a very common phenomenon. There are many types of coughs. Some people will have dry coughs frequently. There are many causes of dry coughs. Some are caused by allergies, and some have a lot to do with one's own physique and environment. Everyone should pay attention to what is causing the dry cough. Sometimes dry cough is caused by allergic bronchitis and should be treated in time.

Have you ever experienced dry cough? Especially some people often have dry cough in their daily lives. When dry cough occurs, everyone should pay more attention. It is also important to understand what dry cough is. Let’s take a look at some of the causes that may cause dry cough.

The causes of allergic cough are complex, but mainly include two aspects, namely the constitution of patients with allergic cough and environmental factors. The patient's physical constitution, including subjective conditions such as "genetic quality", immune status, mental and psychological state, endocrine and health status, is an important factor in the patient's susceptibility to allergic cough. Environmental factors including various allergens, irritating gases, viral infections, residential areas, living conditions, occupational factors, climate, medications, exercise (hyperventilation), food and food additives, eating habits, social factors and even economic conditions may be more important causes of the occurrence and development of allergic cough. The increasing trend in the incidence of allergic cough is also related to the susceptibility caused by the patient's allergic constitution and environmental factors.

Judging from the inconsistency in the onset of allergic cough in monozygotic twins, environmental factors may play an important role in the onset of allergic cough. Contact with allergens in the environment is often a necessary condition for the expression of allergic cough genes in patients, and the concentration of allergens in the environment can often determine the expression level of allergic cough genes. Modern medicine believes that the formation of airway allergic inflammation in patients with allergic cough is the result of the combined action of many factors. Clinical workers should distinguish between primary and secondary factors in order to carry out prevention and treatment work in a targeted manner. In addition, the age at which the patient first comes into contact with the above-mentioned adverse environmental factors, the severity of the adverse environment, the frequency of contact, and the duration of contact are also important factors in determining whether the patient will transform from the pre-allergic cough state to allergic cough disease. They are also key factors in determining the prognosis and outcome of patients with allergic cough disease. In daily life, certain environmental factors that induce allergic coughs, such as dust mites, fungi, pollen and other allergens, viruses and climate change, often persist and are difficult to avoid. In addition, with the improvement of modern living standards, new allergens frequently enter people's lives, people have more opportunities for business trips, travel, and vacations, and their activity areas are constantly expanding, so the scope of contact with allergens is also increasing. Therefore, the prevention and treatment of allergic coughs is often more difficult and difficult to prevent.

At present, most authors believe that the many factors that cause allergic cough should be divided into two categories: pathogenic factors (Trigger) and predisposing factors (Contributor). Pathogenic factors refer to the factors that cause the first attack of allergic cough. They are the "trigger" and main cause of allergic cough, and play an important role in the occurrence and development of allergic cough. Predisposing factors refer to the factors that induce the reactivation of latent allergic cough or acute attack of allergic cough on the basis of allergic cough. They are one of the comprehensive predisposing factors in the process of allergic cough attack, and play an important role in promoting the recurrence and further development of allergic cough. Among the above two categories of factors, some factors such as allergens, irritating gases and harmful gases, occupational factors, viruses, food and drugs have dual effects, which can not only lead to the occurrence of allergic cough, but also play an important role in the development of allergic cough. However, we should make it clear that all environmental factors are not the only factors that determine whether allergic cough occurs. The atopic quality of the allergic cough patient himself is also very important.

As for what is dry cough, through the detailed introduction above, I hope everyone can pay attention to dry cough. If dry cough occurs in normal times, you should be able to find out the cause in time, and then carry out some scientific treatment according to the symptoms. Sometimes dry cough is caused by some tracheal diseases. Everyone should pay attention to their physical fitness in time.
