How do I know if I have bronchial asthma (asthma)? Bronchial asthma is a chronic disease with recurrent attacks that can be easily confused because the symptoms are partially similar to those of chronic bronchitis, emphysema, certain heart diseases and infections, and the treatment is often very different. How can we know if it is asthma? Lu De, Department of Whistling Medicine, Shandong Qianfo Mountain Hospital Whether you have bronchial asthma please check the diagnostic criteria for bronchial asthma (Bronchial Asthma Prevention and Control Guidelines 2008 edition developed by the Chinese Medical Association Whistling Branch): 1. Recurrent episodes of wheezing (often evident during whistling), shortness of breath, chest tightness or coughing are mostly associated with exposure to allergens (i.e. things that cause our allergies), cold air, physical and chemical stimuli, and Viral upper whistle infections, exercise, etc. 2. During an attack, a scattered or diffuse, predominantly whistling phase croup can be heard in both lungs, with a prolonged whistling phase (this is to be determined by a physician’s examination). 3.The above signs and symptoms can be relieved by treatment or by themselves (asthma can be partially relieved by itself). 4.Except wheezing, shortness of breath, chest tightness and cough caused by other diseases (this point is very important, that is, other causes of wheezing must be excluded before asthma can be determined). 5, the clinical manifestations are not typical (such as no obvious wheezing or signs), should have at least one of the following tests positive: (1) positive bronchial excitation test or exercise excitation test; (2) positive bronchial diastolic test FEV1 increase ≥ 12%, and the absolute value of FEV1 increase ≥ 200ml; (3) peak whistle flow (PEF) intra-day (or 2 weeks) variation rate ≥ 20%. A diagnosis of asthma can be made if articles 1 to 4 or 4 or 5 are met. Obviously, these criteria are set for the physician, as a patient, as long as there is “labored wheezing”, “wheezing with movement”, “tightness in the chest” or ” Sometimes these discomforts can be relieved on their own, so you should see a whistle doctor promptly to find out if you have asthma. The doctor will do some tests to establish the diagnosis on a case-by-case basis.
