To judge whether asthma comes on or not, we need to combine several aspects. Some people in life have asthma-like symptoms, which may be caused by bronchitis or cough, not asthma. The most direct way to judge asthma is to go to the hospital for examination. Doctors can judge whether the clinical manifestations of comprehensive patients are asthma by bronchial stimulation experiment or bronchiectasis experiment.
Asthma has premonitory symptoms when it occurs, and it is similar to bronchitis or common cold and cough, so it needs to be judged. Frequent sneezing, stuffy nose, itchy eyes, cough symptoms, it is best to see a doctor immediately. This situation may be a precursor of asthma, so patients may have difficulty breathing and white foam sputum. Generally, cough will not cause dyspnea, and it will not get worse at night. The process of asthma-induced cough attack is very fast. Usually, the cough is very serious in a few minutes. It may recur after remission. Some people cough badly at night, which means asthma is very serious. Therefore, it is necessary to understand the symptoms related to asthma and learn to distinguish them from other diseases such as asthma.
Asthma symptoms: After asthma occurs, the patient has a serious cough, sneezing, stuffy nose and itchy eyes. With the development of the disease, severe breathing and dyspnea appeared, and the onset suddenly occurred. Some asthma patients will feel that breathing is not smooth, breathing time is short, exhaling time is long, and breathing process is difficult.
There are many severe coughs and expectorations after asthma, which are mainly caused by bronchial inflammation or bronchospasm. Cough and expectoration decrease in the process of asthma, and respiratory symptoms are the main symptoms. After asthma, bronchospasm slowly disappears, and cough and expectoration symptoms are aggravated after discharge of secretions. In addition, the sputum caused by cold is light yellow, and the sputum of asthma patients is white foam.
