I. What is asthma?
Asthma is a chronic inflammatory disease of the airways. Chronic inflammation develops in the airways with increased reactivity; when exposed to various risk factors, the airways become obstructed and airflow is blocked (caused by bronchoconstriction, mucus plug formation and increased inflammation). Causes recurrent episodes of wheezing, dyspnea, chest tightness and coughing, especially at night and early in the morning.
Second, how to diagnose asthma early?
1. Episodes with croup with expiratory dyspnea are typical symptoms. In severe cases, the patient is forced to sit and breathe and cannot lie down.
2. Nighttime and early morning attacks are common, and patients often wake up because of this and cannot sleep. Dry cough or coughing up a lot of white foamy sputum is a common accompanying symptom.
3. Some patients have cough as the only symptom, and the cough is obvious at night and lasts for a long time, and when anti-inflammatory coughing is ineffective, it should be considered as variant asthma.
4. Many patients may have a history of eczema, allergic rhinitis or other allergic diseases. Many patients have a history of similar disease or other allergies in their family.
5. Asthma is often misdiagnosed as upper sensation and bronchitis and treated inappropriately. If you have a frequent “cold” with chest tightness that lasts more than 10 days, it may be asthma.
6. Asthma related to allergies often develops in specific seasons or environmental conditions. Children with recurrent nocturnal coughing and waking in the early hours of the morning are almost certainly asthmatic. Coughing or wheezing after exercise is often a sign of exercise-related asthma.
7. Recurrent respiratory tract infections with poor antimicrobial therapy and significant effect of short-acting bronchodilators may also be asthma. Suspicious asthma may not be asthma if the response to one or two courses of asthma treatment is poor.
Three, pediatric asthma triggering causes:
1, caused by genetic factors. Boys are generally more common than girls, and asthma occurs more often in people with allergies.
2, indoor factors including mites cause allergy asthma; damp corners, bathrooms, mold in the refrigerator can also cause; cockroaches are also an allergic factor; in addition, pet dander caused by allergies can not be ignored.
3. Asthma caused by the environment. Pollen in the air, especially in the spring after the flowers bloom, the pollen of trees and plants can cause allergies. Be careful of weeds in autumn as well.
4.Infection of the respiratory tract is also a trigger for asthma.
5.Pollution in the air.
6, Allergies in food is also one, but the real allergy caused by a certain kind of food is relatively small, generally do not easily because of asthma avoid eating.
7, smoking and passive smoking, many studies have shown that in the environment, parents smoking and passive smoking have a significant impact on the future children’s asthma.
8, the pollution of the environment caused by renovation, some chemicals can also cause wheezing. Originally, some affected children do not wheeze, and when they encounter such substances, they will suddenly have an asthma attack. Adults must pay attention.
9, some children are more sensitive to warm and hot air, and more sensitive to movement. In the usual recognition of the situation, you can properly prevent in advance, inhalation of some spray and other drugs before exercise.
