First, will the baby's repeated wheezing become asthma? Infants are generally diagnosed as wheezing, and repeated attacks after 5 years old are diagnosed as asthma. Asthma is a complex disease and a common disease in adolescence. With the increase of age, some children don't get sick after 10. Asthma has certain genetic and environmental factors, and the incidence of allergic constitution is high. However, the baby's illness is caused by a cold, and there may be no allergens, excessive use and other reasons. Therefore, whether it develops into bronchial asthma needs to be observed again. Asthma is an increase in airway reactivity caused by chronic inflammation of airway mucosa, which is characterized by wheezing, shortness of breath, chest tightness and cough. Of course, at present, there is no specific medicine for asthma, but through long-term standardized treatment, asthma can be effectively controlled, which can reduce recurrence or even no attack.
Second, the common disease that causes children to cough repeatedly: upper respiratory tract infection: that is, a cold. Children will have symptoms of repeated cough when they catch a cold, which is easy to cause upper respiratory tract mucosal inflammation. Bronchitis: it is mostly transmitted through upper respiratory tract infection. At first, it was mostly dry cough, and then there was discomfort such as cough and expectoration. In severe cases, hypoxia may occur due to dyspnea. Pneumonia: Children under 2 years old often suffer from bronchopneumonia, which is usually characterized by dry cough, shortness of breath, cyanosis of mouth and lips, and nasal discomfort. Except for newborns, they usually have a fever of 39. Acute laryngitis: When viruses or bacteria pass through the throat, it can also cause throat infection. The most typical symptoms are hoarseness, even no sound, coughing like a dog when inhaling, and wheezing in severe cases.
3. What are the symptoms of childhood asthma? Threatening symptoms such as sneezing, runny nose, itchy nose (allergic rhinitis), itchy throat and cough (allergic cough) are common. There may be irritating cough and white foam sputum. Repeated dyspnea with wheezing, mainly at night. During the attack, both lungs can hear and gasp widely. Severe breathing difficulties will occur when asthma attacks. Advanced patients may have emphysema and pulmonary insufficiency.
