You are not alone if you have ever felt breathless while climbing stairs or experienced sudden wheezing without warning. Asthma is a chronic respiratory condition that affects people of all ages. According to a 2023 report by the Indian Council of Medical Research (ICMR), over 350 lakh Indians have asthma, with a rising number of cases seen in urban areas due to pollution and lifestyle factors.
A study published in Dr Batra’s® Coffee Table Book described a patient from Vadodara, Gujarat, who battled recurrent colds, sneezing, and bronchitis for years and was dependent on antihistamines for relief. After undergoing a Pulmonary Function Test and starting personalised homeopathic treatment, the patient remained symptom-free for 11 months and returned to a healthier, worry-free life
This blog will help you understand the root causes of asthma, how to identify its triggers, and how you can manage it better with safe and personalised solutions
What You Should Know About Asthma
What Triggers Asthma?
Asthma is triggered when airways become inflamed or narrowed, making breathing difficult. The most common causes include:
- Exposure to allergens such as pollen, dust mites, or pet dander
- Respiratory infections
- Physical exertion or exercise
- Cold air and sudden weather changes
- Stress or strong emotions
These triggers lead to wheezing, coughing, chest tightness, and shortness of breath. Understanding these causes can help in avoiding asthma attacks.
Top Causes of Asthma
- Genetics : Family history increases your risk.
- Immune System Imbalance : Overreaction to harmless triggers.
- Pollution : Indoor (cooking fumes) and outdoor (vehicle smoke).
- Allergens : Dust mites, pollen, pet dander, mold.
- Respiratory Infections : Colds or bronchitis can trigger symptoms.
- Weather Changes : Especially cold air or sudden shifts.
- Exercise : Physical exertion can narrow airways.
- Stress : Strong emotions may trigger attacks.
- Smoking : Includes passive smoke exposure.
- Obesity : Extra weight can worsen asthma.
- Food Triggers : Sulfites, shellfish, or dairy in sensitive individuals.
Signs and Symptoms of Asthma
Asthma causes airway inflammation and narrowing, leading to breathing difficulties. Symptoms can vary but commonly include:
- Shortness of Breath : Especially during activity or at night.
- Wheezing : Whistling sound while exhaling.
- Chronic Cough : Often worse at night or after exertion.
- Chest Tightness : Pressure or heaviness in the chest.
- Frequent Colds : Colds that worsen or linger.
- Fatigue : Poor sleep due to night-time symptoms.
Can Genetics or Immunity Play a Role?
Yes, asthma often runs in families. Genetics play a major role, with heritability estimated between 50% and 90%. It is also linked to immune system overreactions to harmless triggers. In severe cases, if left unmanaged, asthma can be life-threatening. In 2023, India reported nearly 20,000 asthma-related deaths (WHO).
Dr Batra’s® pro tip:
Genetic factors play a significant role in asthma development, with heritability estimates ranging from 50% to 90%. While genetics contribute substantially to asthma risk, asthma is a complex condition influenced by both genetic and environmental factors, leading to wide variations in prevalence across populations.
Types of Asthma You Should Know
-
Allergic Asthma
Triggered by allergens like pollen, dust mites, mold, or pet dander.
Often linked with other allergic conditions such as eczema or hay fever.
-
Non-Allergic Asthma
Not caused by allergens. Triggers include stress, cold air, exercise, smoke, or infections.
Usually it develops later in life and may be harder to control.
-
Occupational Asthma
Caused by exposure to irritants at the workplace like chemicals, dust, or fumes.
Common in industries like cleaning, painting, baking, and farming.
-
Cough-Variant Asthma (CVA)
A dry, persistent cough is the main (and often only) symptom.
No wheezing or shortness of breath, which makes it harder to diagnose.
-
Aspirin-Induced Asthma (AIA)
Triggered by taking aspirin or other NSAIDs like ibuprofen.
Symptoms may include nasal congestion, sinus issues, and asthma attacks.
