Emotional asthma: Negative emotions such as anxiety, depression and anger can cause the body to release histamine and other substances that can cause metabolic reactions, increase the excitability of the vagus nerve and decrease the responsiveness of the sympathetic nerve, thus causing or aggravating asthma attacks. This is because negative emotions can lead to a decrease in the body’s immune system, thus making it susceptible to viral attack and causing respiratory tract infections, which can trigger asthma. Diagnosis: 1. Recurrent episodes of wheezing, dyspnea, chest tightness or coughing, mostly related to exposure to allergens, viral infections, exercise or certain irritants. 2.Disseminated or diffuse, expiratory phase dominated croup can be heard in both lungs during the attack. 3.The above symptoms may be relieved by treatment or may resolve on their own. 4.Exclude other diseases that can cause wheezing or dyspnea. 5.For those with atypical symptoms (such as no obvious wheezing or signs), at least one of the following tests should be positive: (1) If the basal FEV1 (or PEF) is <80% of normal value, FEV1 (or PEF) increases by more than 15% after inhalation of β2 agonist. (2) PEF variability (measured by peak expiratory flow rate meter, measured once in the morning and once at night) ≥ 20%. (3) Positive bronchial excitation test (or exercise excitation test). (6) Whether the patient has negative emotions such as anxiety, depression and anger present. Exercise asthma: Also known as exercise-induced asthma, it is a special type of manifestation of bronchial asthma. Exercise can be present as an individual trigger velvet as one of multiple triggers in a specific patient with asthma. Exercise croup can occur at any age and is more common in men than in women. Most patients experience chest tightness, shortness of breath, dyspnea, wheezing, and pronounced croup can be heard in the lungs 6-10 minutes after the start of strenuous exercise and 2-10 minutes after the cessation of exercise. Asthma attacks may gradually resolve within 0.5-1 hour; in a few severe cases, they may last for 2-3 hours. In rare patients, the above asthma symptoms may appear 4-13 hours after exercise, which is called "exercise-induced delayed asthma response". Diagnosis: Chest tightness, wheezing, shortness of breath, cough, dyspnea, chest pain, nervousness, stomach discomfort, sore throat, etc. Some patients may not have typical asthma symptoms, such as headache, abdominal pain, muscle cramps, fatigue and unusual sensations during exercise, but bronchospasm may be detected by pulmonary function measurements before and after exercise.
