Depending upon the causes of asthma, they can be divided into various types
1 Allergic Asthma: The most common type . When there is a history of recurrent runny nose with sneezing or other forms of allergy e.g skin allergy, drug allergy in early age, then allergic asthma can occur. This form gives good response to inhaled corticosteroids
2. Non allergic type: They have asthma like features but differ at cellular levels. They response only temporarily to inhaled corticosteroids
3. Occupational Asthma: Long term i.e over 20 years of exposure to certain organic dusts at work can lead to this type of asthma.
4. Adult onset Asthma: occurs in late age is usually non allergic, and responds to high dose of inhalers containing corticosteroids.
5. Asthma with obesity: some patients with obesity have all respiratory complaints but lesser allergic component.
Respiratory complaints get triggered on exposure to viral infections, smoke, allergens (pollens, drugs, food, animal, insects, fungii), exercise, change in weather, exhaust fumes, or strong smells
Any of these can lead to onset of asthma in predisposed individuals as mentioned in the list above.
