What causes bronchial asthma?

Bronchial asthma is referred to as asthma. It is a chronic inflammatory disease of the airways. In mild cases, it can cause slight obstruction of breathing in patients. In severe cases, it can lead to irreversible narrowing of the airways. People with this disease People often experience recurring symptoms of wheezing, shortness of breath, chest tightness or coughing. Most patients have attacks or worsening at night or early in the morning. This disease can sometimes be relieved on its own or improved with effective treatment.

The causes of bronchial asthma mainly include the following two points: 1. Genetic factors

The prevalence rate of relatives of patients with bronchial asthma will be higher than that of the general population, and the closer the genetic relationship, the worse the condition. The more severe it is, the higher the prevalence of the disease in relatives. This means that if one or both of your parents are bronchial asthma patients, your chance of suffering from bronchial asthma will be much higher than that of people from other normal families. 2. External environmental factors

In addition to the physical factors affecting many people's bronchial asthma, it is also mainly caused by the stimulation of the body by the external environment. For example, some people are allergic themselves and will have strong allergic reactions to certain things. These allergens often include pollen, dust, fish, shrimp, crab, eggs, milk and other substances. When these allergic people are exposed to these Allergens are likely to induce bronchial asthma.

The environmental factors mentioned here also include changes in weather temperature and movement factors. For example, some people will develop bronchial asthma when the temperature suddenly cools down or when they exercise strenuously.

In general, bronchial asthma is a relatively common disease, and the incidence rate in children is higher than that in young adults, in cities than in rural areas, and the incidence rate in the elderly is also on the increase. Since bronchial asthma has an obvious genetic tendency, this is a fact that we cannot change. However, as long as we try to avoid the environmental factors that cause bronchial asthma and enhance the body's resistance, the disease will be eliminated to a large extent. to achieve more effective relief.
