Asthma is a chronic respiratory condition that affects millions of individuals worldwide. Characterised by inflammation and narrowing of the airways, asthma can cause a range of symptoms from mild wheezing to severe breathing difficulties. Understanding the different types of asthma is crucial for effective management and treatment.
Different Types of Asthma and How Can They Be Treated
Talking along the lines, the editorial team of Onlymyhealth got in touch with Dr Shani Mann, Respiratory Medicine, Sharda Hospital, to delve into the various types of asthma and how they can be treated. Here is what he shared with us.
1. Atopic Asthma
Atopic asthma, also known as allergic asthma, is the most common type of asthma. It is triggered by exposure to specific allergens such as dust mites, pollen, pet dander, mould spores, and certain foods. Individuals with atopic asthma have an overactive immune system that responds to these allergens by inflaming and constricting the airways. Treatment often involves identifying and avoiding allergens, along with medications like inhaled corticosteroids, bronchodilators, and allergy shots (immunotherapy) to manage symptoms and reduce inflammation.
2. Non-Atopic Asthma
Non-atopic asthma is not primarily caused by allergens but by other factors such as irritants, respiratory infections, exercise, cold air, stress, or certain medications. Unlike atopic asthma, non-atopic asthma does not involve an allergic reaction to specific substances. Treatment may include avoiding triggers, using bronchodilators to alleviate symptoms, and controlling inflammation with corticosteroids.

3. Drug-Induced Asthma
Some medications can trigger asthma symptoms in individuals with or without a history of asthma. Known as drug-induced asthma, these medications may irritate and constrict the airways, leading to symptoms such as coughing, wheezing, chest tightness, and shortness of breath. Treatment involves discontinuing the offending medication and using alternative drugs under medical supervision.
4. Occupational Asthma
Occupational asthma occurs due to exposure to various substances known as respiratory sensitizers in the workplace. These substances can include chemicals, dust, gases, fumes, and biological agents like animal dander proteins or enzymes used in specific industries. Treatment focuses on avoiding exposure to the triggering agents, using respiratory protective equipment, and implementing proper workplace safety measures.
5. Exercise-Induced Asthma
Exercise-induced asthma is triggered by intense or prolonged physical exertion, leading to airway constriction and inflammation. Factors such as dry or cold air, high pollen counts, and exposure to airborne allergens during exercise can exacerbate symptoms. Treatment options include using bronchodilators before exercise, warming up before physical activity, and avoiding exercising in cold or dry environments whenever possible.

In addition to specific treatments for each type of asthma, there are general management strategies that can help individuals control their symptoms and improve their quality of life. These include:
Controller Medications: Long-term control medications such as inhaled corticosteroids, leukotriene modifiers, and long-acting beta-agonists help reduce airway inflammation and prevent asthma symptoms.
Rescue Medications: Quick-relief medications like short-acting beta-agonists provide immediate relief during asthma attacks or flare-ups.
Monitoring and Action Plans: Regular monitoring of symptoms, peak flow measurements, and the development of personalised asthma action plans with healthcare providers help individuals manage their condition effectively.
Lifestyle Modifications: Avoiding triggers, maintaining a healthy weight, staying physically active, and quitting smoking can all contribute to better asthma control.
A Final Word
Understanding the different types of asthma and their respective treatments is essential for effective management of this chronic respiratory condition. By working closely with healthcare providers and implementing appropriate treatment strategies, individuals with asthma can lead active and fulfilling lives while keeping their symptoms under control.
