Why do children have bronchial asthma? These 3 reasons, you have to find out early
Bronchial asthma is the most common chronic airway disease in childhood. In recent years, the prevalence of childhood asthma in my country is on the rise. Incidence rates have risen, but parents of children with asthma have not raised their awareness of asthma as a result. On the contrary, because of cognitive insufficiency or uneven medical level, the overall control level of childhood asthma is not ideal.
Bronchial asthma is a disease that seriously endangers children's health, and has a great impact on children's learning, life and activities. If not treated properly or in a timely manner, it may develop into adult asthma or protracted and impaired lung function. Some children may lose their physical activity ability as a result, and in severe cases, if treatment is not timely, there may be life-threatening conditions.
For better protection, parents had better learn more about this knowledge and take relevant preventive measures. You can start from the cause first, pay attention to whether the child is at high risk factors, or prevent it in advance.
Why do children have bronchial asthma?
- Genetic factors: Bronchial asthma is a disease with obvious genetic tendency and familial aggregation tendency. There are parents of asthma patients in the immediate family, or the parents themselves have asthma disease. Take more precautions, pay attention to whether the child has the possibility of the disease, and diagnose and treat as soon as possible. However, the increase in the incidence of childhood bronchial asthma is not all genetic factors, and its incidence is also related to environmental factors.
- Allergens: that is, substances that can cause airway allergies, the most common of which are house mites, which are also the greatest harm of indoor allergens and an important pathogenic factor for asthma. However, in the past decade, cigarette smoke caused by smoking has also become an important indoor allergen in children with asthma.
Children with asthma are more likely to develop asthma in a smoking environment. The more common outdoor allergens are pollen and grass powder, as well as strenuous exercise, climate change and a variety of non-specific stimuli. For example, inhaling cold air, distilled water mist, etc.
- Nervous, spiritual and endocrine: The onset of some asthma patients is also related to emotions, and mental factors may also induce asthma. If the fetus is repeatedly infected by respiratory viruses, especially syncytial virus, during pregnancy, it will increase the possibility of allergic reactions and asthma after birth. In addition, if the mother smokes actively or passively during pregnancy, it also affects the lung function of the fetus.
Bronchial asthma in children is generally characterized by recurrent wheezing, coughing, shortness of breath, and chest tightness as the main clinical manifestations. Generally, the attack is more severe at night or in the early morning, and parents of children with bronchial asthma should pay more attention during this time period. Because childhood bronchial asthma is a disease that is more harmful and more dangerous in severe cases, it is recommended that parents of children with high risk factors take preventive measures to reduce accidental hazards.
