不同类型的哮喘br是什么onchitis?
Asthmaticbronchitisis the swelling of small airways inside the lung causing cough and breathlessness. Bronchialasthmais separated into allergic and nonallergic (intrinsic) asthma according to its respective triggers.
- Allergic asthma:Symptoms are triggered by anallergic reaction, which means that theairwayof the affected person reacts more intensely than necessary often to a harmless substance. Allergic asthma often initially presents in early childhood and adolescence and is often due to a hereditary predisposition.
- Intrinsic asthma:Initially presents at the age of 30-40 years and is caused by different factors. Triggers may include respiratory tract infections, genetic incompatibility with certain medications, or chemical or toxic substances from the environment (smog, ozone, dust, etc.)
- As with special forms of bronchial asthma, asthma is also prevalent in severelyoverweightwomen. Specific characteristics also are associated with asthma in smokers.
Depending on severity:
- Acute:Usually, it occurs due to a viral infection; rarely, a bacterial infection is involved. It may start as cold. Symptoms may last 1-2 weeks; the condition is temporary. Typically, it does not cause permanent breathing problems in most people. However, people with respiratory diseases, such as asthma, or those with a weakened immune system are at an increased risk of complications.
- Severe:Doctors consider it as severe if a personcoughsand produces mucus for at least 3 months in 1 year for 2 years in a row. Although the severity of symptoms does not always remain constant, the disease does not go away. It may lead to further respiratory problems. The common cause iscigarette smoking. Eventually, it may lead to permanent damage to thelungs.
