World Asthma Day 2022: Covid Pollution; common asthma triggers | Health

World Asthma Day 2022: Asthma or bronchial asthma is a chronic inflammatory disease of the airways that causes them to narrow and swell, causing periodic bouts of coughing, chest tightness, shortness of breath and of wheezing. There are different types of asthma and therefore the triggers are different, but the classic signs mentioned above remain the same. Common types of asthma are allergic asthma, cough variant asthma, non-allergic asthma, nocturnal asthma, and occupational asthma.

According to experts, smoking and outdoor pollution are the most common triggers of asthma in Delhi NCR. On World Asthma Day (May 3), we spoke to experts about various triggers of the disease.

“The most notable trigger is tobacco smoke which causes irritation of the lower respiratory tract. Second-hand smoke, called smoke created by the smoker and inhaled by a second person, is also a major trigger causing asthma. Inhalation dust mites, a type of microscopic, can hypersensitize the upper and lower respiratory tract. In Delhi NCR, the most common trigger is outdoor pollution,” says Dr. Avi Kumar, Senior Respiratory Consultant, Fortis Escorts Heart Institute Ohla New Delhi.

Sinus infections, allergies, pollen, breathing in certain chemicals, and acid reflux are other common triggers for asthma attacks. Recovering from Covid can also put you at risk.

“The increase in allergies after Covid has been a consistent feature. Patients using medication should intensify their treatment with bronchodilators, antiallergics and inhaled steroids. All known triggers such as smoke, dust, strong odors should be completely avoided. Patients with a preponderance of allergies should be vaccinated annually against the flu. Great care should be taken to identify and neutralize asthma triggers,” says Dr. Kumar.

Dr Nimish Shah, Consultant, Pulmonary and Sleep Medicine – Sir HN Reliance Foundation Hospital Mumbai, says that most asthmatics (almost 70%) are allergic or atopic and most will have coexisting nasal symptoms such as rhinitis ( runny nose/stuffy nose).

Dr. Shah also lists common asthma triggers:

* Weather change

* Exposure to dust, tree or grass pollen

* Exposure to strong odors such as perfumes and odors

* Exposure to occupational smoke or dust

* Exposure to certain classes of drugs, eg. aspirin, NSAIDs (nonsteroidal anti-inflammatory drugs), ibuprofen, diclofenac, blood pressure medications (beta-blockers)

* Stress

* Non-adherence to treatment

* Abuse of alcohol, cigarettes or drugs

* Employment or income issues leading to non-compliance

* Viral infections

* People with exercise-induced asthma will have worse symptoms during exercise.
