The severity of asthma varies from person to person. Most patients with asthma are able to control their symptoms well with or without medication.
Sometimes, you may notice the asthmatic symptoms gradually or acutely worsen — this is known as an ‘asthma attack’. In severe cases, asthmatic attacks may require hospitalization, or can even be life threatening (though less common).
What causes Asthma?
Asthma is due to inflammation of the lung bronchi (which are small connection respiratory passage tubes to carry air in and out of the lungs). When a person is having asthma, the bronchi is triggered by environmental factor and becomes sensitized and inflamed.
The airways become narrow, causing the airway muscles to tighten — this results in an increase in mucus production leading to difficulty of breathing and a productive cough.
Common cause/ triggers of Asthma include
- Viral infection
- Airborne triggers such as animal fur, dust mites, pollen, grass
- Inhaled chemicals in surrounding environment
