Causes of Asthma
- Genetic factor: A person who comes from a family with chest or skin allergies is more susceptible to asthma than those who come from families without allergies.
- Environmental factor: The patient is exposed to some stimuli and irritants to the respiratory tract
These stimulants are the stimulants that spread in the job or work we do, including wood dust, medicines, pigments, animals, insects and candidiasis. These stimulants produce occupational asthma, which accounts for 15% of asthma.
Other stimulants are pollen, cold, cold air, sports, cigarette smoke, transport smoke, perfume, emotional stimulants and medications such as anti-inflammatory drugs (NSAIDs) and beta-blockers.
Symptoms of Nubia
- Contraction of muscles surrounding the airway (airway)
- Inflammation of lining membrane of airways (airway)
- The mucus secretion is increased in the airway, causing constriction and difficulty in passing through the air. The patient then suffers from regular asthma symptoms and signs.
