Is normal lung function asthma?

The lungs are a very important internal organ in the human body and are closely connected to our respiratory system. When the human body breathes, it mainly inhales oxygen through the nasal cavity, filters it through the respiratory tract and lungs, and then exhales carbon dioxide. This is a complete respiratory circulation system. Asthma is a very common respiratory disease in our lives. Some people ask if they have normal lung function, is there still a possibility of suffering from asthma?

For asthma, respiratory function tests, bronchial dilation tests, bronchial provocation tests, and peak flow rate and its daily variability tests can be considered. It is one of the important bases for evaluating the degree of on-site control and helps to diagnose the disease. You can also consider allergen testing, which can also clarify the situation. Regarding the lung function test you mentioned, it depends on what kind of test it is, because in an asthma test, some indicators may be normal, but that does not mean you do not have asthma.

Normal lung function does not rule out asthma. For some allergic asthma, lung function is normal during the period when there is no attack. Therefore, to confirm whether it is asthma, we must first look at the clinical symptoms, and secondly, look at the results of lung CT, chest X-ray, blood routine, and electrolyte tests to confirm whether it is allergic asthma, cardiac asthma, or bronchial asthma. First, you need to check whether it is allergic asthma. If so, then you need to see what the allergy is. You should avoid contact with certain things at ordinary times. In addition, you need to get a desensitization injection and a human placental tissue fluid injection (this is to enhance immunity). At the same time, you need to have a balanced diet, eat everything, enhance immunity, and exercise moderately at ordinary times. If you have an attack during this period, you need to use a spray to relieve it. The spray is the asthma medicine with the least side effects, but you cannot spray it many times a day, as it will cause dependence.

The symptoms in the chronic persistent stage are more hidden, and parents often do not find that their children have wheezing, but they often cough and produce sputum. At this time, some parents tend to ignore the treatment of asthma, thinking that the child does not have wheezing, and that it will be fine as long as the sputum is coughed out. But this is not the case. Doctors can find out that the child’s lung function is still poor at this time by monitoring FEV1 and peak expiratory flow rate. The results often indicate that the asthma is in an unstable state. At the same time, although the child does not have obvious clinical symptoms such as wheezing and shortness of breath, he still has breath holding and chest tightness at night, and needs to sit up to breathe, and needs bronchodilators to relieve. In this case, it can be clinically judged as the chronic persistent stage of asthma.
