What is asthma?
Asthma is a chronic respiratory disease that affects the airways in the lungs. People with asthma have airways that are inflamed and sensitive, making them more likely to react to triggers such as allergens, irritants, exercise, or changes in temperature or humidity.
How many type of asthma?
- Allergic asthma.
- Seasonal’ asthma.
- Occupational asthma.
- Non-allergic asthma.
- Exercise-induced’ asthma.
- Difficult asthma.
- Severe asthma.
- Brittle’ asthma.
There are generally two main types of asthma:
- Allergic or extrinsic asthma: This type of asthma is triggered by allergens such as pollen, dust mites, animal dander, and mold. It is the most common type of asthma and is often associated with other allergic conditions such as eczema and hay fever.
- Non-allergic or intrinsic asthma: This type of asthma is not triggered by allergens and is often caused by factors such as exercise, cold air, respiratory infections, stress, and irritants such as smoke and strong odors.
It’s worth noting that some people with asthma may experience a combination of both types, or their asthma may change over time, from one type to the other. Additionally, there are subtypes of asthma based on different criteria, such as severity, age of onset, and underlying inflammation patterns. These subtypes are still being studied, and there is no consensus on their classification at this time
