Symptoms accompanying bronchial asthma are usually paroxysmal – they can occur suddenly, during sleep, due to stress, after intense exercise or as a result of infection or high air pollution. The most common symptoms of asthma include:
- nagging feeling of breathlessness related to bronchospasm
- tightness of the chest,
Importantly, not all asthmatics have all of these symptoms – it happens that the only manifestation of the disease is a cough. Paroxysmal symptoms, such as dyspnea or troublesome cough, usually disappear only after administration of medications. In the absence of appropriate treatment, asthma symptoms worsen with consequent permanent respiratory impairment.
WHAT CAUSES BAND ASTHMA?
There is a fairly large group of factors that can cause asthma and trigger the underlying inflammatory mechanisms and allergic reactions. These factors can be easily divided into:
genetic – some patients are genetically predisposed to bronchial asthma, and they can be activated by the surrounding allergens;
environmental – these are mainly allergens, air pollution, cigarette smoke, dust and mites. This group also includes pollen, pet hair, medicines and some food products. The presence of an allergen that causes or worsens symptoms of bronchial asthma may vary, and attacks may occur at different times and under varying circumstances.
Occasionally, bronchial asthma is associated with or associated with other conditions, such as bronchitis or atopic dermatitis.
