Why do you sometimes feel short of breath? Sometimes feeling shortness of breath may be caused by asthma. The causes of asthma are as follows:

Asthma is related to polygenic inheritance. The prevalence of asthma in relatives of asthma patients is higher than the prevalence in the population, and the closer the relationship, the higher the prevalence; the more serious the patient's condition, the higher the prevalence of his relatives.

2. Allergens

1. Indoor and outdoor allergens: Dust mites are the most common and most harmful indoor allergens and are an important cause of asthma worldwide. Dust mites exist in secretions such as fur, saliva, urine and feces. Fungi are also one of the allergens present in indoor air, especially in dark, humid and poorly ventilated places. Common outdoor allergens: Pollen and grass powder are the most common outdoor allergens that cause asthma attacks.

2. Occupational allergens: Common allergens include grain powder, flour, wood, feed, tea, coffee beans, silkworms, pigeons, mushrooms, antibiotics (penicillin, cephalosporin), rosin, reactive dyes, persulfates, ethylenediamine, etc.

3. Drugs and food additives: Aspirin, propranolol (Inderal) and some non-corticosteroid anti-inflammatory drugs are the main allergens of drug-induced asthma.

3. Triggering Factors

Common air pollution, smoking, respiratory viral infection, pregnancy, strenuous exercise, climate change; various non-specific stimuli such as inhalation of cold air, distilled water droplets, etc. can induce asthma attacks. In addition, psychological factors can also trigger asthma.

Comprehensive treatment measures for asthma are as follows:

1. Eliminate the causes and predisposing factors.

2. Prevent and treat co-existing diseases, such as allergic rhinitis, reflux esophagitis, etc.
